Best lap timer for 2021

When you love vehicles, odds are good that you simply additionally love going quick. And whereas the informal exhilaration of velocity on a superbly twisting street or the accomplishment of tackling a tricky path are sufficient for many people, the extra pushed really feel the necessity to go quicker. You may make a automobile quicker with extra energy or higher suspension, however the most effective (and least expensive) efficiency improve that you would be able to make is to the part between the seat and the steering wheel: you, the motive force.

Among the best instruments that can assist you grow to be a quicker driver is a exact lap timer. Whereas that may be so simple as setting a stopwatch at the beginning of every session, most devoted racing lap timers use GPS expertise to robotically mark every lap’s starting and finish, separating the time for every and permitting the consumer to see how adjustments to your racing line and braking factors have an effect on your total velocity and RPM. The most effective examples additionally log and save your classes digitally — typically together with car efficiency check knowledge or video — for overview later.

It may be troublesome for a novice to take a look at GPS knowledge and lap instances and know precisely the way to go quicker. Ideally, that is the place an skilled driving coach is available in to assist make heads or tails of the data. Nonetheless, if you cannot discover human assist, a brand new class of digital monitor teaching gadgets might be able to assist. These gadgets use a mix of synthetic intelligence and predictive lap timing to investigate the logged knowledge and make recommendations, typically in actual time on the monitor, to enhance your velocity for every subsequent lap.


The Goal Solo 2 is among the most really helpful lap timers for newbie racer and high-performance driving occasions — each novices getting severe about racing and seasoned lovers — and with good purpose. The Solo 2 options an easy-to-read 3-inch show with colour customizable backlight and huge, legible textual content. The unit is about as plug-and-play as they arrive: Mount it, energy it and head onto any of greater than 2,000 preloaded tracks to have your laps tracked and logged by way of exact GPS/Glonass with 10Hz decision.

Along with robotically monitoring your present lap time quantity, the Goal Solo 2 can show cut up instances and predictive lap instances (I will clarify the distinction in a second). The Solo may also be used for efficiency benchmarks exterior of the circuit for point-to-point races, drag races or simply to get exact 0-to-60 instances. Whenever you’re accomplished driving, logged timing, GPS, accelerometer and gyro knowledge might be recalled both on the machine itself or on a PC by way of Wi-Fi.

At simply $400, the Goal Solo 2 affords primarily every thing you’ll want to rise up and operating with exact timing on and off the monitor and nothing that you do not. Extra skilled drivers with a bit extra to spend also needs to take into account the $700 Goal Solo 2 DL; the costlier mannequin upgrades with ECU connectivity permitting it to additionally show and log knowledge out of your automobile’s onboard sensors and allows helpful options like a programmable shift mild. The modular DL may also be upgraded to log a number of exterior sensors and even hook up with Goal’s Smartycam system. Solo 2 can be utilized in all your efficiency conditions: hill climbs, regularity, velocity races in closed circuits, and level to level races. It supplies highly effective knowledge overview and data all the knowledge you want whereas racing such because the sector instances. You simply want the correct cables to attach the Solo 2 to your automobile.


The candy spot in Racelogic’s Vbox line of racing monitoring programs, the Efficiency Field Contact can be one of many model’s latest fashions. It is priced ($680) slightly below the Goal Solo 2 DL, however with out the flexibility to connect with your automobile’s ECU or exterior sensors, its characteristic set is nearer to that of the Goal Solo 2.

Nonetheless, the PBT is not with out benefits of its personal. The unit is constructed round a full-color 4.3-inch show that’s not solely bigger, however extra customizable than the Goal items’ — not that you need to be spending an excessive amount of time admiring the display whereas tearing across the monitor. Vbox additionally claims that its proprietary Delta-T and Delta-V predictive lap timing algorithms are extra correct, making the PBT doubtlessly a greater studying software.


Goal’s Observe Day equipment bundles the Solo 2 DL with its Smartycam HD 2.1 digicam. The 2 gadgets might be hung out of your windshield on the identical double-bracket suction cup mount, providing you with a easy technique to monitor and file driver and car efficiency knowledge with video. That is along with all the flexibility and upgradability that make the DL mannequin such a incredible selection by itself.

If there’s one weak spot, it is that the SmartyCam is not very cinematic. It solely captures at 720p and 30 frames per second, plus you will have to decide on between a slim (67-degree) or huge (84-degree) subject of view on the time of buy. That is decrease decision, body charge, FOV and total picture high quality than a GoPro, the present gold-standard for motion cameras. So, if visible constancy is paramount, it might be price mating a 5K GoPro Hero 9 with the Solo 2 DL and studying to make use of third-party modifying software program to manually overlay your logged knowledge.

Nonetheless, the Solo 2 DL and Smartycam combo are unmatched of their performance and ease of use. The digicam can robotically overlay any of the myriad of knowledge captured by the Solo 2 DL — like a G-force meter, a dwell monitor map, digital gauges and extra — onto its captured footage, making it straightforward to share your on-track exploits and victories with out having to study to edit video. Plus, it robotically begins recording together with the Solo 2 DL as quickly as you hit the monitor, so you will by no means have to fret about forgetting to hit file — or being unable to achieve due to a restrictive harness.

Here is the catch: We may solely discover the Observe Day Bundle on Goal’s UK-based web site, so if you happen to do not need to pay in kilos and ship internationally, you will have to order the Smartycam and the Solo 2 DL individually on the hyperlinks beneath and join them by yourself.


In regards to the measurement and form of a small radar detector, the Vbox Sport packs in all the high-resolution GPS monitoring and precision lap timing of the Efficiency Field Contact, however with out the touchscreen. In truth, there isn’t any display in any respect! Whereas this will likely seem to be a downgrade, the headless setup has its benefits.

For starters, no display means nothing to distract you whereas ripping it up on the monitor. GPS, gyro, accelerometer and timing knowledge are saved on an SD card for retrieval and evaluation later, so you will not be tempted to look away from the street. The compact measurement additionally permits for extra versatile mounting, you may tuck it into the nook of the windscreen, out of your line of sight. Plus, the whole unit is waterproof and pretty light-weight, which makes it additionally excellent to be used on bikes, boats, ATV and side-by-sides, bicycles, massive R/C craft and planes or just about something you may mount (or zip-tie) the Vbox Sport to.

And if you happen to ever want a display, Bluetooth connectivity means that you would be able to nonetheless view dwell lap instances or overview logged knowledge on a paired smartphone within the Racelogic app or any of the really helpful third-party lap timer apps beneath.


Garmin’s Catalyst can and does perform as a lap timer, displaying your present lap and cut up instances on its 7-inch colour touchscreen and robotically logging your on-course GPS/Glonass place with 10Hz decision and accelerometer knowledge everytime you hit the monitor. It additionally captures video with a 1080p, 30fps digicam. Nonetheless, the Catalyst’s biggest trick takes place after you come back to the pit.

On the finish of every session, the Catalyst makes use of synthetic intelligence and a built-in sensor to investigate the captured knowledge and video, remixing your greatest segments right into a True Optimum Lap — a video illustration of the quickest lap attainable based mostly on the monitor, the car and your talent degree. This, based on Garmin, is best than a cut up time as a result of it not solely tells you the way a lot quicker you are getting, however the way to be quicker by suggesting the place enhancements might be made.

On subsequent classes, Catalyst may even give audio suggestions in actual time that can assist you obtain the True Optimum Lap — hints like apex sooner, brake later or good phase — which might be performed by means of the machine’s inner audio system, the automobile’s stereo system or perhaps a Bluetooth headset or comms system. Heavy-duty mounting bracket securely positions Catalyst contained in the cockpit. Even higher, as you enhance, so does your True Optimum Lap. The Garmin may retailer a number of profiles for various drivers and autos.

So why is not this the most effective total lap timer? Nearly as good because the Catalyst is at teaching novice to intermediate racers, it is lacking a couple of options. For starters, the $1,000 Catalyst would not hook up with the automobile’s ECU just like the Goal Solo 2 DL and may’t log exterior sensors. Plus, it is solely ready for use for circuit racing and HPDEs; point-to-point racing, drag racing and 0-to-60 testing is just not at the moment supported.

Even with these shortcomings, the Garmin Catalyst is — in need of an skilled human coach driving shotgun — one of the best ways to get quicker on the monitor and can develop alongside along with your talent cap.

TrackAddict boasts an in depth characteristic set that may rework the iPhone or different smartphone in your pocket into a powerful racing recorder. The app takes benefit of the telephone’s GPS antenna to file monitor place and show lap time, cut up time, predictive time and extra with an easy-to-use interface. It may well additionally file HD video utilizing the telephone’s digicam and overlay knowledge and graphics for sharing.

Along with lap timing for circuit racing, TrackAddict options modes for point-to-point races — helpful for autocross or rallying — drag racing and even a low-speed 4×4 trails mode that logs pitch and roll data. Plus, it is free with in-app purchases for less than probably the most superior options.

TrackAddict can be in a position to ingest exact GPS knowledge from an exterior receiver — just like the Vbox Sport — for extra exact high-resolution positioning than the telephone’s antenna can supply and may even hook up with Bluetooth adapters to log knowledge out of your automobile’s ECU — equivalent to engine velocity, throttle place and extra.

Harry’s Lap Timer

For a very long time, Harry’s Lap Timer dominated the roost as the go-to smartphone lap-timing software. It is extraordinarily versatile, in a position to log and show a large gamut of racing knowledge, and really simply customizable in how that knowledge is displayed. I personally used variations of Harry’s for a few years earlier than switching to TrackAddict’s extra informal streamlined interface, however with smarter options like laps to pit — which calculates what number of laps you’ve got left earlier than needing to refuel — and higher predictive timing, Harry’s is total the higher app.

It is also the costlier app with three variations to select from. For many, the bottom $9 Rookie app is nice sufficient to get began timing laps, however to match the extent of TrackAddict’s performance (with video recording) requires an improve to the mid-spec Petrolhead product for $20. The flagship Grand Prix model ($28) boasts really distinctive options like the flexibility to check two video laps side-by-side and even distant management a number of GoPro and Sony cameras. Even at its priciest, the associated fee is cheap for what you get, nevertheless it’s exhausting to compete with free.

Most lap timers have to be suction-cupped to the windshield or bolted to the dashboard, however the instrument cluster is probably the most streamlined place to watch your efficiency from the motive force’s seat. Nearly each automobile already has an instrument cluster, however an aftermarket alternative means you are not essentially caught with the factory-installed gauges.

Goal MXG 1.2 Sprint Information logger incorporates a 7-inch TFT show — the most important Goal affords — and is designed to perform as a full-digital racing instrument cluster. Pulling knowledge out of your automobile’s ECU or a number of exterior digital or analog sensors, it may show velocity, a tachometer with shift mild, temps, oil stress and extra. Plus, with its included GPS antenna and inner accelerometer, the MXG can robotically monitor and show lap instances and cut up and predictive instances with all the constancy matching or exceeding the Solo fashions, storing racing knowledge on an SD card for post-race retrieval and evaluation. And just like the Solo 2 DL, the MXG is appropriate with Goal’s Smartycams.

For all however purpose-built race vehicles, a cluster alternative is full overkill and slightly impractical, however the Goal MXG 1.2 is probably the most no-compromise lap timer flex.

What ought to lap timer do?

The plain reply is {that a} lap timer ought to precisely measure, separate and retailer your lap instances when you race round a monitor, nevertheless it’s a skosh extra complicated than that. For starters, you will be too busy driving to manually mark your laps, so lap timer ought to make use of GPS to robotically monitor if you cross the start-finish line.

The most effective lap timers will retailer your laps for evaluation and comparability with future classes and also needs to present some type of efficiency suggestions whereas on the monitor. This may very well be so simple as displaying a cut up time or extra complicated.


The addition of a handlebar mount allows the Goal Solo 2 for use on bikes, as nicely.

What to search for in a GPS lap timer?

The extra correct the machine’s positioning, the extra correct your measured instances will probably be, so a high-quality GPS antenna is paramount. Search for a receiver appropriate with the International Navigation Satellite tv for pc System, which mixes monitoring on each the GPS and GLONASS satellite tv for pc constellations for probably the most exact positioning.

At 80 mph, a automobile travels round 117 ft each second. So, for fast-paced autos on a race monitor, refresh charge (measured in hertz) for positioning knowledge is simply as essential as accuracy. I’ve seen specialty GPS trackers attain as excessive as 16 to 20Hz, however most good lap timers can have a refresh charge of round 10Hz. Extraordinarily low cost timers (or older smartphones) can dip as little as 1 to 6Hz, which causes inconsistent detection of the beginning/end line and inaccurate timing.

Talking of the end line, lap timer constructed for racing purposes ought to have built-in location knowledge for widespread racetracks. That does not imply you will be a map, however having the identical place for the end line (in addition to the identical beginning factors for monitor segments) makes it simpler to check and share your time and efficiency with different drivers.

Although not strictly crucial — as with the screenless Vbox Sport — a big, easy-to-read show may be very good to have. Ideally you will be watching the grid and never the clock as soon as the inexperienced flag drops, however large, legible numbers implies that you will not must squint to look at your cut up. Alongside that very same line, lap timer also needs to be a knowledge logger, because it’s a lot safer and simpler to take a look at lap knowledge from the pits.


Predictive timing helps the motive force enhance with instant suggestions on adjustments to the racing line.

What’s predictive lap timing?

A cut up time is the distinction between your tempo in your present lap and that of your earlier greatest. Race tracks are damaged up into segments and splits are normally calculated on the finish of every one. So if you happen to get to the top of the primary phase a second before final time, your cut up is minus 1 second. Nonetheless, if you happen to lose two ticks on the subsequent phase, its cut up will probably be plus 2 seconds and, on the finish of the lap, your complete cut up will probably be plus 1 second. Cut up timing aids to find the sections of the monitor which might be providing you with probably the most hassle and will help you see how changes have an effect on your total lap time.

Predictive timing — typically referred to as delta timing — takes that idea a step additional, calculating in actual time how your present efficiency stacks up along with your earlier greatest and estimates of how lengthy your present lap will take based mostly on adjustments to your racing line, acceleration and braking. This may be so simple as an LED that turns inexperienced if you’re quicker and purple when slower, or a dwell updating lap time prediction. If, for instance, braking a contact earlier in a particular bend ends in a quicker exit velocity, you might even see your predictive time drop immediately. This makes it simpler to pinpoint small enhancements that may be misplaced ready to finish a lap and even the present phase.

What’s a driving coach?

Skilled drivers are ready to take a look at their lap instances, possibly evaluate notes with different drivers and see the place enhancements might be made. Nonetheless, novice racers may have the assistance of a driving coach to make heads or tails of the info. Whereas there is no such thing as a alternative for an skilled human driving shotgun, digital driving coaches just like the Garmin Catalyst or the Apex Professional Driving Coach might be extraordinarily useful. 

Digital teaching is like predictive lap timing on steroids, going past simply displaying if you’re quicker to telling you how to get quicker. The Catalyst combines GPS, accelerometer and digicam knowledge to trace you. On the finish of your session, the most effective segments of a number of laps are mixed right into a True Optimum Lap — a hypothetical greatest lap based mostly in your efficiency.


Catalyst’s coolest characteristic is its means to generate a “True Optimum Lap” based mostly in your captured knowledge and video.


This, in itself, is not significantly particular — many lap timers can calculate an optimum lap — however the distinction is that the Catalyst takes that knowledge and makes use of it to provide suggestions in your subsequent driving session. The AI will give audio prompts and hints telling the motive force to, for instance, brake later right here, apex sooner there, or keep on the gasoline only a bit longer. The extra laps you full, the higher the recommendations returned by the Catalyst. Moreover, as a result of the optimum lap relies in your greatest segments, the driving coach additionally grows along with your talent cap.

How do you mount a lap timer?

Most standalone racing lap timers will ship with some type of suction-cup mount, however not all the time. Ensure that to examine before you purchase. A suction cup is the best mounting choice, permitting the machine to be connected to the windshield like a GPS navigator or radar detector after which simply eliminated on the finish of your lapping session. Windshield mounting additionally offers a lap timer’s GPS antenna the clearest view of the sky for the most effective satellite tv for pc positioning accuracy.

A safer mounting choice is a bolt-in dashboard bracket. This semipermanent mounting methodology is safer than a suction cup — particularly within the occasion of a collision — and has the additional advantage of retaining your windshield away from obstructions. You’ll have to change or drill into your dashboard to bolt it in, and you may need to be sure that your chosen mounting place would not block the GPS antenna.

For motorbike and powersports purposes, a handlebar mount can be utilized to carry your lap timer securely in place. Goal even affords padded bar mounts for its Solo 2 and Solo 2 DL fashions. Full instrument cluster replacements just like the Goal MXG are probably the most time and labor intensive installations and may solely be tried if you happen to completely know what you are doing.


Windshield or dashboard mounting offers the lap timer the most effective connection to the satellite tv for pc constellations and probably the most correct timing.

Issues to contemplate about lap timer apps

Probably the most cost-effective technique to begin timing your laps at this time is to obtain a lap timer app and easily use the telephone that is already in your pocket. Apps like Harry’s Lap Timer and TrackAddict supply characteristic units that rival the most effective devoted GPS lap timers on this record, however there are a couple of catches.

The efficiency of a lap-timer app is extremely dependent in your telephone, since it is the handset’s GPS and accelerometers doing the heavy lifting. Newer gadgets are normally as much as the duty, however an older telephone might be in charge for an inconsistent and irritating lap-timing expertise. There are some things you are able to do to provide your telephone a leg up.

First, you will have to price range for a dashboard or windshield mount; your pocket or a cup holder will not do. The telephone will want a transparent view of the sky to provide its GPS antenna the most effective shot at correct positioning. Search for a agency, secure mount — not a type of versatile goosenecks — that locks into place and permits the accelerometers to extra exactly measure G-forces, ensures that the handset will not go bouncing across the cabin if you hit a bump and should even allow you to use your telephone’s digicam to file video of your laps. As an additional advantage, you too can use the mount when navigating house on the finish of the day.


A locking mount, like this Ram X-Grip Suction Cup, will maintain your telephone extra securely than a cup holder whereas timing laps and enhance GPS accuracy.

Ram Mounts

A cell phone’s GPS is designed with energy administration and navigation in thoughts, which may imply compromising on refresh charge. Many older telephones can have GPS refresh charges as little as 1 to 6Hz, which is okay for turn-by-turn instructions however is not the most effective for exact, high-speed measurement. That refresh charge could drop even decrease — beneath even 1Hz — to assist save energy when the display is off or the battery is low, even on comparatively new telephones. So, you will need to preserve your telephone plugged in and awake throughout your laps.

In case your telephone’s not reducing it however you do not need to make the leap to a devoted timer, take into account augmenting your machine with an exterior Bluetooth GPS antenna — just like the Vbox Sport or the Garmin GLO 2 — so as to add extra exact, high-refresh positioning. Each Harry’s and TrackAddict help dozens of third-party receivers, however you will need to double-check for compatibility along with your telephone’s OS. You too can add an adapter that connects to your automobile’s diagnostics port to permit the app to seize ECU knowledge, equivalent to engine velocity, throttle place and extra.
