FAQ
How do I change the design?
Swipe left or right on the calculator to switch to the next design. You can also choose from the list in Settings (the gear button) → Design.
Can I remove the ads?
Purchase "Remove Ads" (a one-time in-app purchase) in Settings and ads will no longer be shown.
What happens to "Remove Ads" when I change phones?
Tap "Restore purchases" in Settings using the same Apple Account or Google Account you used to buy it. You can keep using it without paying again. It cannot be transferred between iPhone and Android.
I can't hear any sound
Check that BGM and sound effects are turned on in Settings. On iPhone, no sound plays while the Ring/Silent switch is set to silent. The app plays over your music without stopping it.
Is my calculation history saved?
