Read full description

It is a simple muscle training timer application that can perform timer and recording at the same time. You can start the timer as soon as you set the number of sets, training time, and break time. After the timer expires, it is automatically recorded on the calendar. If you save in the timer list in advance such as daily training, muscle training, stretching, you can always start the timer with one tap. It is automatically saved in the calendar so you can review the training content and number of times later. Because it supports the background, you can use it while listening to videos and music, and you will be notified by notification. [App Features] When using the timer, you will be notified by notification even if you do not open the app. If you write down and save the number of reps in the timer list, you can use it as a simple muscle training record. You can review past timer records on the calendar. You can use it while listening to music. If you like the app, I would be grateful if you could review it. Developers have read your reviews and are motivated!

About

Windpuls

Read full description

Wind is no longer an unpredictable disruptive factor - with Windpuls it becomes a measurable influencing factor. We are revolutionizing the world of wind measurement to help athletes, developers and the energy industry get the most out of the wind. The app connects to the Windpuls Sensor and allows for precise recordings: - We measure in three dimensions how the wind flows towards the sensor on a moving object. - We measure how fast the sensor moves along a route. - We determine the inclination of the sensor, as this is required for converting the inflow conditions into wind. - We record the real wind at every measuring point regardless of your own position and movement. - We can assign a position on the map to the sensor. - Measuring the sensor rotation allows us to determine accurate wind and weather data in any situation.
