Smart Pools vs EarTimer

The smart swimming pool app can obtain the water wave status and water temperature of the swimming pool in real time through sensors. When a person falls into the water and the water wave amplitude is large, an alarm will be triggered to monitor the water temperature in real time.

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.
