Free calculator: scientific, fuel, currency and receipt OCR

Free calculator: scientific, fuel, currency and OCR

Aksiyon Calculator brings basic arithmetic, a scientific calculator, fuel cost calculation, a currency converter, a unit converter and receipt OCR together in one app. It is free on the App Store and Google Play as an iPhone calculator and an Android calculator. Students, couriers, taxi drivers and office workers share the same pocket tool.

The home screen is enough for simple math. Brackets, percentages, degrees/radians and long results live in scientific mode. History stays on your device and can be cleared without an account.

Scientific calculator

Sine, cosine, tangent, logarithms, exponents and square roots for the field and the classroom. The theme studio raises contrast; work in dark or light mode. The tablet scientific layout offers wider key spacing.

Fuel cost calculation

Enter kilometers, L/100 km consumption and the price per liter. The fuel calculator returns the total cost and the approximate liters needed. Intercity trips, delivery routes, taxi and courier teams use the same screen.

Fuel cost and everyday tools

Fuel, percentage and discount tools

Currency and unit converter

Check USD, EUR and other rates from inside the app with the currency converter. The unit converter handles length, weight, volume and temperature for kitchen or construction math on your phone. Without a live rate, you can continue with the last known value.

Receipt OCR

Read the amount from a photo of a receipt or price tag. No more typing numbers by hand in the checkout line or while archiving at home. The result can be saved to your calculation history.

Themes, keys and tablets

Key combinations, appearance and the iPad / Android tablet layout are shown in the store screenshots. iPhone and Android are the same Aksiyon Soft product; updates arrive through the App Store and Google Play.
