How to use

This application is an application that counts the rhythm of "2-1-2-1" when performing convict condtioning.

In "Reps", enter the number of exercises (reps) to be performed in one set. In "Counts per a reps", enter how many seconds you want to exercise each time. In Prisoner training, the basic interval is "2-1-2-1" = "6 seconds", which repeats the bottom position in 2 seconds, the wait for 1 second, the start position in 2 seconds, and the wait for 1 second.

After inputting, click / tap the character "start" to start counting from "5 seconds later" at the specified rhythm. Take the start position within 5 seconds.


For example, if you enter "60" in "Counts per a reps", an alarm will sound every 60 seconds. I think that it can be used when you want to manage the elapsed time in events such as hanging.
