R vs HIIT Timer / Interval Timer

R-Timer is a timer that plays the sound of a gong - designed for sports matches such as boxing. The sound of a gong is played at the beginning and end of a round. You can also make some wooden clappers make a sound just before the end of a round. New functionality has been added for providing notifications while the app or OS is in suspend mode. Enable the notification functionality to receive notifications through messages and gong sounds. The notification functionality settings can be found under the settings screen. Notification Functionality in Suspend Mode - The volume of the notifications is determined by the OS settings. - Putting the app in suspend mode and active mode repeatedly will make the end time slip. - Notification sounds may not be played successfully on low specification devices. - The number of configurable notifications is determined by the OS. Setting too many notifications will cause the notification functionality to stop working. - The app may behave differently between running in normal mode and in notification mode. - To stop notifications, please stop the app or open the app's settings screen. Functionality - Notifies you of the beginning and end of a round by playing the sound of a gong. - Find out the end time by looking at the settings screen - Added at the start of the round the voice, such as "Round One" (up to 1-30 round) - Add a voice such as "box" or "Fight" at the start of the round - Can give a signal just before the end of a round by playing some wooden clappers. - Can configure a different sound for the end of the last round. - As you might not be able to tap on the screen, you can start, pause, and restart the app by shaking the device. - Pause and restart the timer while it is running. - Configure it only once and next time you will be able to use it straight away. - Configurable volume Note: the volume in the app is determined by the volume set on your device, so if the volume is too low, please increase the volume on your device. Specifications Setting the Number of Rounds : 1 - ２00 Time per round : 0[sec] - 100[min]59[sec] Preparation time : 0[sec] - 1000[sec] Signal before end of round : None - Time per round Resting time : 0[sec] - 1000[sec] Time display : 24[hour] or AM/PM Signal Start of round : Gong, Chinese gong, Bell End of round : Gong, Chinese gong, Bell End of last round : Gong, Chinese gong, Bell Signal before end of round : Wooden clappers, Chinese gong, Bell Note: the volume in the app is determined by the volume set on your device, so if the volume is too low, please increase the volume on your device.

The high-intensity exercise should be done at near maximum intensity. The medium exercise should be about 50% intensity. The number of repetitions and length of each depends on the exercise, but maybe as little as three repetitions with just 20 seconds of intense exercise. The specific exercises performed during the high-intensity portions vary. Most of the research on HIIT has been done using a cycling ergometer, but other exercises like a rowing ergometer, running, stair climbing and uphill walking can also be effective. There is no specific formula for HIIT. Depending on one's level of cardiovascular development, the moderate-level intensity can be as slow as walking. A common formula involves a 2:1 ratio of work to recovery periods, for example, 30–40 seconds of hard sprinting alternated with 15–20 seconds of jogging or walking, repeated to failure. The entire HIIT session may last between four and thirty minutes, meaning that it is considered to be an excellent way to maximize a workout limited by time constraints. Use of a clock or timer is recommended to keep accurate times, the number of rounds, and intensity. Quoted from: https://en.wikipedia.org/wiki/High-intensity_interval_training
