The app operates on a freemium model. Users can try the first calculator in each category for free. A one-time purchase unlocks all 35+ calculators, providing lifetime access and including future calculator updates without any subscriptions.
The description does not specify exact compatibility details for operating systems (iOS/Android) or device models. However, it explicitly states that the app is 100% offline, meaning no internet connection is required for its functionality.
