❓ FAQ

How do I switch between modes?
Tap the mode button (≡) on the display to pick from Basic, Scientific, Converter, Graphing, or History. The interface adapts to each mode.
How does the unit converter work?
Switch to Converter mode, pick a category (Length, Weight, Temperature, Volume, Area, Speed, Time, Storage, Energy, Pressure, Fuel, Angle, or Currency), choose units, and enter a value.
Are currency rates live?
Yes — fetched from open.er-api.com when you use the Currency converter. Fails gracefully to 1:1 rates if offline.
Does the app collect data?
No. All calculations stay on your device. No analytics, tracking, or data collection of any kind.
Is there a dark mode?
Yes. Tap the sun/moon icon in the top-right corner of the display to toggle between light and dark themes.
