Full description
An offline scientific and engineering calculator for exploring mathematics on Android.
Use the free calculator for algebraic or RPN input, number bases, constants, unit conversions, memory and local history.
The Pro toolkit plots two functions with pan, zoom and point inspection. Find approximate roots, intersections and extrema; solve scalar equations and nonlinear systems with up to three unknowns.
Work with matrices up to 8 by 8, vectors and complex expressions. Explore descriptive statistics, linear regression, numerical derivatives and adaptive numerical integration.
No advertisements or subscription. The basic calculator is free; Pro is designed as a permanent, one-time unlock. Version 0.1.0 is in testing, and commercial purchasing is not available yet.
Data safety worksheet
Review the exact uploaded artifact, provider behavior and active build variants. The development configuration is not a completed Google Play Data safety declaration.
Calculations, expressions, history and Pro workspace data are processed and saved on the device. No developer-operated account or calculation server is required.
Google Play Billing is integrated for a planned one-time purchase. Google handles the payment flow; the app verifies and caches purchase information for access restoration. The developer does not receive payment-card details. Production purchase configuration is not active in version 0.1.0. No advertising SDK, UMP integration or advertising identifiers are included. Calculations do not require media, microphone or location permission.
Media
Capture at least two authentic screenshots from the final app. Do not use simulated screens, synthetic medical fixtures or old-brand captures. Screenshot language must reflect the actual app; English captions do not imply an English-only interface.
Remaining release checks
