It is a simple list type counter.
It is a specification that you can add or subtract as much as you like by putting a number in the set value.
If you set the initial value, it will be reset to the initial value when the counter is reset.
You can freely customize it by adding a label, changing the background color, changing the font size, and so on.
By registering multiple counters as a group and switching the group freely, you can use them properly according to the purpose.

It's a simple but functional and convenient app.
