Common questions

Does it work offline?
Core calculations work on your device. Ads and downloadable fonts need a connection.

Where is history stored?
On your device. Android may back it up according to your backup settings. You can delete entries or clear history in the app.

Why is a result approximate?
Calculations use floating-point precision. Numerical calculus and fraction approximation have precision limits. Check the angle mode when using trigonometry.
