直線距離計測 is a useful Android app developed by ishi-daishi. It falls under the category of Utilities & Tools and offers a simple and convenient way to measure distances. Whether you need to track a specific distance for an event or want to register your location for certain rewards, this app has got you covered.

The app features a single screen interface where you can input the desired distance to measure. It continuously displays the straight-line distance from the starting point and vibrates when you reach the specified distance. You can then reset the distance and start measuring again from that point.

In addition to the basic functionality, the app also offers optional features like playing a beep sound, turning off the backlight, and keeping the screen on. However, please note that these optional features may not work on all devices.

The app has been tested on the Xperia (SO-01B v2.1) and MEDIAS WP (N-06C v2.3) devices. While the basic functionality works on both devices, the optional features are still being optimized for the MEDIAS WP device.

The developer plans to further improve the app by expanding the compatibility of the optional features to more devices and making it work in the background as a service. As this is the developer's first Android app, they appreciate your understanding and support.
