This is the best app for people who need to measure multiple times at the same time, such as managers of club activities!
It also has a timer function that can be used for various purposes such as training time management, studying, cooking, and so on.
The timer also runs in the background, so you can measure your time while doing other tasks.

As a runner myself, I've always wanted to have an app like this. This is an app from the perspective of runners and managers.

Stopwatch
- Split time, lap time
- Up to 8 stopwatches (up to 17 depending on the device) work simultaneously
- Save both lap and split times
- Allows you to look back at saved data on a calendar
- This is useful for sports practice and competitions, such as track and field events. In addition, it is also useful when you want to measure multiple times in various aspects of your daily life.

Time measurement linked to video (paid service)
- Slow playback, fast forwarding, and playback position of the video can be freely selected.
- The playback position of the video is linked to the time on the stopwatch (if the video is playing slowly, the stopwatch will also play slowly).
- Accurate measurement of goal time for short distances
- Measurement of lap times of multiple runners (video can be stopped and lap times can be pressed simultaneously)
The measured times can be copied and pasted into Excel or Google spreadsheets for sharing and analysis.

Timer
- Timer can repeat up to 99 times
- Intervals can also be set
- Up to 5 different intervals can be set.
- Sound can be set to on or off (vibrate can also be set)
- Works in the background too
- Also suitable for Tabata and Tabata style training
