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

Verdict

The call

The clearest difference is rating: GPS Race Timer at 4.5 against E85 App's 4.0. GPS Race Timer also leads on ratings volume (2.7K vs 33) and iOS requirement (12.2 vs 17.0). E85 App's advantage is update cadence (every 9 days vs every 7 months) and review sentiment (49% vs 35%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

GPS Race Timer holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: GPS Race Timer has 2.7K ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 35% of GPS Race Timer's written reviews are positive against 49% of E85 App's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

GPS Race Timer ships an update every 7 months, E85 App every 9 days. The most recent releases landed on September 20, 2026 and September 18, 2026 respectively.
