BIWA-TEKUビワテク is a free Android app developed by HIGASHIOMI CITY that offers a mobile stamp rally for different cities and towns. The app allows users to participate in virtual walking rallies and earn milestone points by walking a certain number of steps. It also provides various health consultations and examinations to help users achieve their health goals and earn health points.

The app accumulates points that users can use to participate in the annual lottery for prizes provided by the cities and towns. The milestone points are placed at regular distances towards the goal, encouraging users to walk more and achieve their health goals.

BIWA-TEKUビワテク uses the GPS function to track the user's steps and calculate the acquisition and consumption of calories. However, the app warns that the continued use of GPS running in the background may decrease the device's battery life.

It is important to note that the app is not involved in any way with Google, and the QR Code used in the app is a registered trademark of DENSO WAVE INCORPORATED.

Overall, BIWA-TEKUビワテク is a unique and engaging app that encourages users to stay active and achieve their health goals through virtual walking rallies and health consultations.
