Race Timer vs EarTimer

MEASURE YOUR ACCELERATION. YOUR WAY. SpeedGate turns your iPhone into a GPS acceleration timer for measuring real-world vehicle performance. Set the speed you want to reach — 0–60 mph, 0–100 km/h, or any custom speed — and SpeedGate automatically detects when you start moving and times your run. No manual stopwatch. No need to tap the screen while launching. Just set your gate, start the test and drive. CUSTOM SPEED GATES Choose your own target speed in mph or km/h. Use one gate for a simple acceleration test, or unlock two gates with SpeedGate Pro to measure two targets during the same run. AUTOMATIC LAUNCH DETECTION SpeedGate detects the beginning of your run automatically. Hands-free audio cues help you focus on driving while the app handles the timing. GPS + MOTION SENSOR FUSION SpeedGate combines GPS and iPhone motion sensor data to create a fused speed and acceleration trace. Sensor calibration helps verify bias, noise and device orientation before measuring performance. ANALYZE YOUR RUNS Review your acceleration results, distance, duration, maximum speed and measurement quality. SpeedGate Pro adds detailed telemetry graphs and aggregate performance charts to help you analyze and compare your runs.

SpeedGate is designed for drivers who want a simple, flexible way to measure and analyze acceleration using the sensors already inside their iPhone. Always drive responsibly and follow local traffic laws. Perform acceleration tests only where it is safe and legal to do so.

Timer alerts, just for your ears. EarTimer is a timer app for iPhone that plays timer sounds through connected Bluetooth earphones. It is designed for situations where you do not want sound to play through your iPhone’s built-in speaker. Made for moments like these • Early starts while your family sleeps • Quick naps beside a sleeping baby • Mornings in hotels and shared rooms • Naps on trains and planes • Quiet breaks in libraries and shared spaces Key Features • Set timers in hours, minutes, and seconds • Two timer sounds • Test external-audio playback before starting; when no external output is connected, the test uses vibration instead • Pause, resume, or cancel a running timer • On supported devices, control the timer from Live Activities on the Lock Screen or Dynamic Island Free with optional ad removal EarTimer is free to download and includes a non-personalized banner ad on the Timer screen. A one-time “Remove Ads” in-app purchase removes the banner. Existing customers who purchased EarTimer before it became free continue to use the app without ads. Earphone-first playback EarTimer plays the selected timer sound only while an external audio output is connected. If your earphones disconnect, the app will not switch the timer sound to the iPhone’s built-in speaker. Important Information For reliable playback through your earphones, do not force-quit EarTimer. Audio may be interrupted by phone calls, Siri, other audio apps, Bluetooth reconnection, device restarts, or iOS system conditions. Requires an iPhone running iOS 26.0 or later.
