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. VEHICLE PROFILES Associate your runs with a vehicle and keep performance results organized. SpeedGate includes one vehicle profile, while Pro lets you create and manage multiple vehicles.

Your saved SpeedGate data remains on your device, with export and backup options when you choose to use them. 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.

A quiet break. A focused study session. A reminder through your headphones. EarTimer helps you keep track of time in libraries, shared workspaces, and other quiet places. Set a countdown and hear the timer through connected wired headphones or Bluetooth earphones, including AirPods. MAKE TIME FOR YOUR NEXT TASK • Take a short break between study or work sessions. • Set aside time to read or focus without watching the clock. • Keep track of a quiet rest in a shared space. SET, START, AND STAY IN CONTROL • Choose hours, minutes, and seconds. • Check the current audio output before you start. • Test playback through your connected headphones. • Pause, resume, or cancel a running timer. • See and control your timer in a Live Activity on the Lock Screen, and in the Dynamic Island on supported iPhones. HOW HEADPHONE PLAYBACK WORKS EarTimer starts timer audio when a supported external audio output is connected. If that output disconnects, the app pauses its audio rather than intentionally routing the timer sound to the iPhone speaker. Without headphones, the system timer may still show an alert and vibrate; the selected timer sound does not start. KEEP THESE LIMITATIONS IN MIND Keep EarTimer running; do not force-quit it before your timer ends. Headphone audio is not guaranteed after force-quitting, an iPhone restart, or termination by iOS. Calls, Siri, other audio apps, Bluetooth reconnection, and system conditions can interrupt playback. Reopen EarTimer with headphones connected to prepare playback again. Check your audio output and volume before use. Do not rely on EarTimer as your only alarm for an important wake-up or deadline. FREE WITH OPTIONAL AD REMOVAL The free app can show a non-personalized banner ad on the Timer screen. A one-time Remove Ads in-app purchase removes the banner. Customers who purchased EarTimer before it became free retain their ad-free experience. Purchases can be restored in Settings. Advertising and privacy choices are explained in the app's privacy policy. Requires an iPhone with iOS 26.0 or later. Headphone audio requires a compatible connected output; Live Activity availability depends on the device and system settings.
