SciCalc

Scientific Calculator for iPhone & iPad. Version 1.0.1

About

SciCalc is a clean, fast scientific calculator with real expression parsing, a scrolling tape of past calculations, persistent history, memory, degree/radian trig, and a dedicated landscape keypad. No ads, no accounts, no data collection.

Getting started

Type a whole expression and press =. Operator precedence and parentheses are handled correctly. Try 5sin(30) + π².
2nd key reveals inverse trig (sin⁻¹, etc.), 10ˣ, eˣ, x!, τ, and cube root.
Ans inserts the last result. After pressing =, an operator (+, ×, etc.) continues from Ans automatically.
Tap any past calculation on the tape to insert its expression, its result, or copy the result to the clipboard.
Rotate to landscape for a wide 9×5 keypad that puts every function on one page.
DEG / RAD button at the top-left toggles angle mode.

FAQ

Why does -2² equal 4 instead of -4?

Unary minus binds tighter than the power operator in SciCalc, matching the iOS built-in Calculator. If you want -(2²) = -4, type -(2^2) or 0 - 2^2.

Does 3.5! work?

Yes. Non-integer factorials use the gamma function: 3.5! ≈ 11.6317.

Is my history backed up?

Your history is stored locally on your device using iOS UserDefaults. It survives relaunches and updates, but is not synced across devices. iCloud sync may be added in a future version.

Where is my data sent?

Nowhere. SciCalc makes no network requests. See the Privacy Policy for full details.
