GPS Race Timer vs hash camera

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

Hash Camera helps you create timestamp evidence for important photos. Capture photos with server receipt time, optional blockchain anchor information, photo hash, and QR verification metadata. The app saves a QR-marked copy to your photo library and stores an evidence record on the server for later verification. You can verify evidence by selecting a photo from your library or scanning a QR code. Verification results show whether a Hash Camera evidence record can be found, whether the record is still retained, and what trust level applies. Hash Camera is designed for personal records, secondhand transactions, rental handovers, online acceptance checks, and insurance-related documentation. Important notice: Hash Camera is not a notarization service, forensic analysis service, insurance claim decision service, or marketplace guarantee.
