About the Count Expiration Date

The plus and minus buttons are available as long as they are within the Count Expiration Date.

The count expiration date is extended by watching the ad.

Ads can be viewed up to 10 times a day.

It is also possible to eliminate this expiration date with in-app purchases and allow unlimited counting. In-app purchases can be made from the setting screen that opens with the black setting button at the bottom left of the main screen (startup screen).

How to use GP Counter


Count at multiple counters

To count at multiple counters at the same time, count on the main screen (startup screen).

The plus button on the right side of the counter is for counting up, and the minus button is for counting down.

Lock counters that will not be used for the time being so that they will not be counted incorrectly. You can switch between locking and unlocking by tapping the lock button between the plus and minus buttons.

If you want to concentrate on one counter, tap the magnify button on the upper left of that counter.
