"Re: Watch" is a stopwatch application specialized for recording time. Major features You can record the lap time, the number of laps, and the split time, and display the time as well as the time. You can resume the recording once it has ended. The stop time can be displayed. The number of laps and lap time will be announced by voice. It is not necessary to keep the app running while measuring. Even if it is terminated, even if the power of the terminal is turned off, the application is restarted and the time measurement continues. When you turn on the recording of location information, it records the time and approximate location of all operations, so it is also possible to keep a record of when and where you were. The recorded locations can be checked by switching to the map display. A history of measurement results remains (sign-in required) While measuring, you can log laps, pause, resume, and stop right from the Lock Screen without unlocking your device (requires iOS 17 or later). ※ When location recording is turned on, the app captures your location only at the moment you perform an action such as Start, Lap, or Stop. It no longer tracks your location continuously in the background.
