Stopwatch is a free and easy-to-use time measuring tool developed by K. Welsing for Android devices. It requires only one permission to write results on the SD card, making it a safe and secure tool for all users.

In addition to measuring total time and lap time, Stopwatch offers a range of additional functions to enhance the user experience. Users can save times and create a list of previously stopped times with individual names. There is also a CSV export function available for the list of all results, which can be saved to Google Drive and opened on Windows.

The stopwatch can be paused, and users can send the results via email. The app is small and can be moved to the SD card, and font sizes are configurable. The scale can be suppressed, and it supports the holo theme of Android 4.x. The app is also suitable for tablets and all sports such as jogging, sprinting, racing, running, and all other actions for which time needs to be measured. It is free without ads, and users can send bug reports and suggestions via email.

Please use this app only when the circumstances are safe for you and others. Use at your own risk.
