Prism Tape Calculator is a calculator with a paper tape. Every line you enter is printed above the keys, the answer updates as you type, and you can tap any earlier result to use it again — with no ads, no tracking and no subscription. THE TAPE • Every calculation you commit is printed to the tape, newest at the bottom, like an adding machine. • The last few lines stay visible above the display, so you always have context. • Tap any line to drop its result into what you are typing now. • Open the full tape to scroll back through everything, swipe to delete a line, or clear it all. • The tape is stored on your device and is there when you come back. SEE THE WHOLE EXPRESSION • The full expression stays on screen — 1,250 × (1 + 8.25%) — not one number at a time. • The result previews live under it before you press equals, so typos are caught before they cost you. • Backspace removes one key at a time (a whole function like sin( in one go). • Press an operator after equals to keep going from the last answer; ans is always a key away. MATH YOU CAN TRUST • Decimal arithmetic: 0.1 + 0.2 = 0.3, exactly. Money math without floating-point surprises. • Percent that behaves the way people mean it: 200 + 15% = 230, 50 − 10% = 45, 20 × 5% = 1. • Thousands separators, sensible rounding, and scientific notation only when a number really needs it. • Clear error messages instead of a mystery “Error”: divide by zero, unbalanced parentheses, invalid input. SCIENTIFIC WHEN YOU NEED IT • Tap sci (or rotate to landscape) for parentheses, powers, roots, sin, cos, tan, ln, log, factorial, π and e. • Degrees or radians. Implicit multiplication works: 2π and 3(4 + 1) mean what you expect. DESIGNED FOR THE PHONE IN YOUR HAND • Big rounded keys sized to your screen, haptic feedback, light and dark mode. • The whole app is a few megabytes and opens instantly. Works completely offline. • VoiceOver reads the expression and every tape line. Supports Dynamic Type. PRIVATE BY DESIGN • No ads. Ever. • No account, nothing to sign in to. • No analytics, no advertising SDKs, no third-party code. • Nothing leaves your device.
