MXTimer is a simple but effective chronometer with two counting modes: forward (stopwatch) - with the ability to time laps and calculate lap deltas in real time (in-place, real-time, best-lap deltas) and backwards (countdown), with the ability to loop and vibrate to alert you to expired time cycles. Time functions are unobtrusive (using minimal device functionality) to avoid unnecessary access permissions on your device. For this reason, the app uses vibration and not sounds. Using sounds requires permissions related to privacy and file access so we designed MXTimer to alert you using vibration instead, which can be turned off. The application also allows you to lock it in the foreground; this way your timers keep working preventing the screen from locking but not using background power or extra battery. You also control whether you want the app to keep your screen on or not. MXTimer can share time data with your other applications and social networking sites if you desire. You may copy data to the clipboard, email it, tweet it or save it. You may also choose from a variety of built-in themes and colors, font sizes and other options. Overall, the app requires permission to vibrate, save time data to your local device and an internet connection if you wish to share the data online. This is all the application does - no access to your private information, phone or contacts or other sensitive information is needed at all. MXTimer is free and contains no advertisements.
