Quick comparison table

1. Home Workout Timer & Tracker

Best for: Interval workouts, gym laps, and repeat timed efforts on iPhone.

If you need a lap timer that handles structured intervals without extra gear, this is the one to try. You can build custom work/rest intervals, save routines, and start a lap session without watching the screen. That makes it useful for running laps, gym circuits, or home workouts where repeat consistency matters more than deep GPS data.

Key features:

• Custom intervals with seconds, reps, or meters.
• Saved training templates for Tabata, HIIT, strength, and core.
• Live distance tracking on running segments when location tracking is on.
• Simple start-and-tap lap flow that stays out of your way.

It's iOS only. Get Home Workout Timer & Tracker or download Home Workout Timer & Tracker on the App Store. It beats a basic phone stopwatch because you're not manually resetting laps or guessing rest times.

2. Harry's LapTimer

Best for: Car enthusiasts who want video overlays and deep sensor data on track days.

Harry's LapTimer suits drivers who want every data point from a track day. It logs GPS, accelerometer, and optional OBD-II info while you drive. The video recording with data overlays is the main draw, so you can watch laps with speed, line, and timing graphics on screen. It supports iOS and Android, but expect a steeper learning curve than a simple stopwatch app. You'll get the most out of it if you read the docs and set up your car, track, and data settings before the session.

3. RaceChrono

Best for: Amateur and professional drivers who want versatile GPS lap timing and analysis.

RaceChrono is one of the most flexible motorsports lap timers you can put on a phone. It handles GPS lap timing, video recording, and data logging in one place. After a session, you can review lap times, sectors, lines, and other telemetry. The free version covers basic timing, and paid tiers unlock deeper analysis and video tools. It works on iOS and Android and pairs with external GPS or OBD-II devices for better accuracy. The interface feels more functional than social, but the data depth is serious.

4. TrackAddict

Best for: Drivers who want telemetry and OBD-II data without a dedicated logger.

TrackAddict turns your phone into a motorsports telemetry and video system. The app records GPS lap timing, OBD-II data, and live telemetry while you drive. That means speed, RPM, throttle, and other channels show up if your car supports OBD-II. It runs on iOS and Android, though an external GPS receiver noticeably improves lap time accuracy over the phone's built-in GPS. There's a lot in the interface, so first-time users may need a few sessions to get comfortable.

5. LapTrophy

Best for: Social track-day drivers who want automatic lap and sector times.

LapTrophy keeps lap and sector timing simple. Drive on a supported track and it automatically starts recording laps and splits. You can compare times with friends and other drivers through the social feature, which makes track days more fun. It works on iOS and Android and feels lighter than full data-logging apps. Setup is straightforward: pick the track, drive, and review times. If you want quick lap times and a leaderboard feel, this sits in a good middle ground.

6. MYLAPS Speedhive

Best for: Racers who need official transponder results at MYLAPS-equipped events.

MYLAPS Speedhive is the app to open when an event uses MYLAPS transponders. You get official race results and personal lap times quickly, without manual timing. Because it ties into formal timing systems, it's widely used in professional and amateur racing around the world. It runs on iOS and Android. The main limitation is dependence on event transponder coverage. This is not a standalone lap timer for practice days or unsupported tracks.

7. SprintTimer - Photo Finish

Best for: Coaches and athletes timing running, cycling, or rowing races.

SprintTimer uses the iPhone camera for race timing and photo finish capture. You film the finish line, and the app timestamps athletes as they cross. That's useful for track and field, cycling, and rowing when you want accurate results without extra hardware. The app is iOS only and really built for straight-line race finishes, not motorsports circuits. For sprint races and training groups, it's a simple way to settle close finishes.

8. Motorlap

Best for: Motorcycle riders and car drivers who want a real-time dashboard.

Motorlap is a GPS lap timer and data logger designed for motorcycles and cars. You get a real-time dashboard during a lap, and the app records telemetry for post-race review. The motorcycle and car views keep the display focused on the data that matters for each vehicle type. It's Android-only, so iPhone users are out of luck. If you ride or drive on GPS-tracked circuits and want lap times plus post-session analysis, this is a solid Android pick.

How we picked these apps

We prioritized clear lap timing, GPS accuracy, and useful post-session data. A lap timer can mean different things, so we covered interval workouts, track days, official race results, and photo finish timing. We avoided apps that require expensive mandatory hardware unless they clearly earned a spot by doing something better than the rest. iOS and Android availability mattered, but we did not rule out strong single-platform apps. Home Workout Timer & Tracker earned the top pick for ease and workout lap timing. Motorsports apps were judged on data depth, telemetry options, and how much they improve phone-only timing.

Frequently asked questions

Do I need extra hardware for GPS lap timers?

No. Most apps work with your phone's built-in GPS. An external GPS receiver or OBD-II adapter can improve accuracy and add data on track, but you don't need one to start.

Are phone GPS lap timers accurate enough for track days?

For casual practice and learning, yes. For official results or tight competitive times, a transponder or dedicated timer is more reliable. An external GPS receiver usually closes some of the gap.

Can any of these apps replace an official transponder?

No. Only MYLAPS Speedhive gives official results, and only when the event runs MYLAPS transponders. Standalone apps are for practice, analysis, or workouts.

Which app is best for interval running or gym laps?

Home Workout Timer & Tracker is the best lap timer for interval running and gym laps because it handles custom work/rest intervals without extra gear.

The verdict

Home Workout Timer & Tracker is the top pick for most lap-timing needs. It's the easiest way to run repeat lap or interval sessions without extra gear. Get Home Workout Timer & Tracker. Motorsports users who need video overlays and telemetry should look at Harry's LapTimer or RaceChrono.
