So you know what it costs while you are still in the store, not just at the checkout. Decimals work too (0.5 for half a pound, for example), and you never have to save anything, that happens on its own.
Mitrechner Plus
With Plus you set a budget and see right under the total how much is left. You can write your lists at home, so at the store you only add the prices. Finished trips go into your history with their date, and statistics show what you spend each month and what you buy most often. You buy Plus once, there is no subscription.
In your language
Mitrechner is available in English, German, Spanish and French. The currency goes by your country, so for example dollars, euros or pesos.
You don’t need an account, and there are no ads. What you enter stays on your phone.
