This app automatically counts the number of times the user pushes up. Launch this app and push it up and put your smartphone under your head. And push-ups will start counting on their own. At this point, the sensor that measures the number of times is located near the illumination sensor of the smartphone, so you should put your head close to it. There are infinite mode and set mode. You can use infinite mode when you want to continue exercising without any restrictions. Set mode can be used when you want to exercise by specifying the set number of times.
