GPS Race Timer vs Sheet Watch

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

Sheet Watch keeps one important spreadsheet value visible on your wrist. Choose a cell in the phone app, refresh it when needed, and see the latest value in the companion watch app or as a watch face complication. Add optional min and max bounds to turn numeric values into a gauge, making progress, quotas, balances, and thresholds easier to scan at a glance. Demo Mode lets you explore the full workflow with local sample data before connecting your own account. When you are ready, secure sign-in lets Sheet Watch read the spreadsheet cell you choose. Sheet Watch is designed as a focused utility. It does not include analytics, does not use a backend service, and does not sync your spreadsheet data to cloud services controlled by the app. The latest snapshot is stored locally for display on your paired devices.
