SciCalc: Scientific Calculator

Real expression parsing, scientific functions, a scrolling tape, and a dedicated landscape layout. No ads, no accounts, no data collection

SciCalc is a clean, fast scientific calculator built for everyday math, science, and engineering work, with the parser-level correctness you'd expect from a real calculator, not a glorified display.

KEY FEATURES

• Full expression evaluation: type the whole problem and press = once. Operator precedence, parentheses, unary minus, and implicit multiplication all just work (so "5sin(30) + pi squared" does what you expect).
• Scientific functions: sin, cos, tan and their inverses (via the 2nd key), natural log, log base 10, log base 2, square root, cube root, x to a power, x squared, reciprocal, factorial, exponential, hyperbolic functions, absolute value.
• Constants: pi, e, tau.
• Degree / Radian toggle for trigonometry.
• Memory: M+, M-, MR, MC with an on-screen memory indicator.
• Scrolling tape: every past calculation sits above the entry line. Tap any past row to reuse its expression or its result.
• Persistent history: your tape survives relaunches. A dedicated History sheet lets you reuse or clear past results.
• Ans variable: the last result is always one tap away.
• Editable expression with a blinking caret, arrow keys, and atom-aware backspace (one tap removes "sin(" or "Ans" as a whole unit, not character by character).
• Landscape mode: a wide 9x5 keypad puts every function on one page, no tab switching.
• iPad support, portrait and landscape.
• Dark UI tuned for long sessions, with haptic feedback on every key.

WHAT YOU WON'T FIND

• No ads, ever.
• No accounts, no sign-in.
• No data collection. No analytics, no trackers, no network requests: your math stays on your device.

Designed for students, engineers, scientists, finance pros, and anyone who's ever wished their calculator could handle a whole expression at once.
