Percemo answers everyday percentage questions: a discount in a shop, VAT on an invoice, a margin or a tip. You type the numbers on its own keypad and see the answer while you type. It works offline and without an account, and your calculations are stored on your phone, not on our server.

Questions and answers

Are my calculations sent anywhere?

No. Percemo calculates on your phone and sends no calculations to us. They are stored on your phone and, if Android backup is on, in your own Google backup.

Does Percemo show ads?

The free version shows a banner at the end of the start screen and of the history and, after every second finished calculation, a full-screen ad when you leave the calculator. If you want, you can watch a short video for 30 minutes without ads. Pro removes all ads.

What does Pro cost?

Pro is a one-time purchase through Google Play, not a subscription. It removes all ads and adds extras such as the history export and presets. Google Play shows you the price before you buy.
