Everything in one app
One calculator. Every calculation.
Stop switching between apps. CueCalc adapts to whatever math you're doing right now.
Standard Calculator
True decimal precision — no floating-point errors, ever. Handles massive integers without overflow.
Scientific Calculator
Trigonometry, logarithms, powers, roots, constants and full memory functions, all one tap away.
Unit Converter
10+ categories including length, mass, and currency with live market exchange rates.
Fractions
Real vertical fraction notation with one-tap simplification and mixed-number display.
Graph Plotter PRO
Plot multiple equations at once on an interactive canvas you can pinch, zoom, and pan.
AR Math Solver PRO BETA
Point your camera at any written equation and tap to capture. Solved entirely on-device — nothing is ever uploaded.
The signature feature
Cues Studio: build your own calculator
A Cue is a reusable formula template. Write an expression once using named variables like gross or vat_rate, and CueCalc automatically builds the input fields — for taxes, engineering, tips, business, or group trips.
- Derived variables computed automatically from other inputs
- Currency & percentage input types with live formatting
- Share Cues via AirDrop — recipients get their own linked history
- Color-coded interpretation bands on every result
Built for speed
Your favorite Cues, one tap away
A frosted pull-tab lives right on the edge of the display. Pull it out and your pinned Cues spring into view — tap one and it runs instantly, no trip through the library, no matter which calculator mode you're in.
- Pin any Cue from its library card in one tap — no drag-and-drop fuss
- Tap a slot to run that Cue immediately — the bar collapses right after
- Free keeps 3 fixed slots; Pro unlocks 6 in two columns, plus "Always Show" to skip the pull gesture entirely
- Your slots are remembered — close the app and they're exactly where you left them
- On iPad, it becomes a vertically-centered rail instead of a pull-tab
