## What is GPS Race Timer?

Measure acceleration times such as 0–60 mph, 60–120 mph and 1/4 mile directly with your iPhone — accurately and without extra hardware.

The app is designed so it doesn’t need to be operated while driving; you just set everything up beforehand while stationary.
Measurements then start automatically — when the target speed is reached or when a start is detected.
You can save results locally on your iPhone and, if needed, export them or transfer them to other devices.

Preset timers: 60 ft, 1/8 mile, 1/4 mile, 1/2 mile, 1 mile, 0 – 60 mph, 0 – 120 mph, 50 – 75 mph, 60 – 120 mph, 0 – 100 km/h, 0 – 200 km/h, 80 – 120 km/h, 100 – 200 km/h. All timers are, of course, fully adjustable.
The free version measures up to two times per run.

How to use the app:

Check the timer settings on the start screen. If everything looks good, place your iPhone in the car where it has good GPS reception and is held securely, then start the acceleration test.
You can adjust the timer configuration in the Settings screen (just tap the relevant timer). Then return to the race screen and follow the previous instruction.

Optional PRO version (in-app purchase):

1. Up to four timers in parallel (instead of two)
2. Precise determination of elevation differences
3. Simulation of a Sportsman start and reaction-time measurement
4. No ad banners

### 1/5 — sht

*2026-08-05, version 3.6*

it’s not fking work, waste my money for non working app

### 1/5 — App doesn’t work

*2026-07-20, version 3.6*

Mph works fine but doesn’t log 1/4 mile or 60 ft times. Got a green bar every time I use it meaning it has a good signal

### 5/5 — Easy to use!

*2026-06-23, version 3.6*

Update 2026-06-23: I sent the author an email asking if this was strictly GPS or also used the much more accurate accelerometer in my phone. No answer. 🫤 I consider it a fun toy only.

Original: This is a *very* easy to use app!  I’m not sure how accurate it is yet, as I’ve only used it two or three times and don’t have anything else to compare it to (now that LapTimer has been disabled by BMW on my M550i — argh 😠).

### 1/5 — Doesn’t work

*2026-05-16, version 3.5*

Just doesn’t work for me. Displays current and top speed so it registering something but as to getting 0-60 to work absolutely nothing

### 1/5 — Can’t scroll down to reset buttons on IPhone SE

*2026-04-22, version 3.5*

I tried using my app on my iPhone SE, but can’t scroll down to one of the buttons at the bottom

### 3/5 — Review

*2026-02-25, version 3.5*

The app is cool, it tracks speed and 0-60 and so on. I have an actual draggy and it said 3.8 0-60 on my draggy but on the APP it said 4.6 so whatever time you get subtract around 0.8 seconds. I know it’s hard to track a cars speed, especially a slow to quick speed through GPS and satellites so I give it props for giving me a close time but it’s a bit off and that’s fine.

### 1/5 — Nope

*2026-02-21, version 3.5*

Does not want to work for me. The reset button does nothing you have to go in and hit race time all over again leaves your speed settings on screen the 60 foot timer starts while you’re still setting still pretty much aggravating and useless.

### 5/5 — RB Alternative

*2026-02-11, version 3.5*

Perfect for the simple Joe that doesn’t do car reviews or professional 1/4 racing. My way of testing a cars potential and health. A+

### 1/5 — Mr

*2026-01-29, version 3.5*

This app doesn’t work every time I test it gives me different numbers also sometimes it doesn’t Evan register the speed that am going I go up to 70 miles per hour it still thinks am on 50

### 2/5 — Doesn’t work most of the time

*2026-01-18, version 3.5*

There’s a good job at calculating your speed and max feet, but it’s virtually impossible to get the actual timer to start. Most of the time it doesn’t start and you’ve just wasted a 0 to 60 run I’ve only gotten it to actually work a couple of times not even sure how it happened. I also have the latest iPhone 17 Pro
