About this app

Cheat Calculator looks and works like a normal calculator… until you decide what the answer should be.

Set a fixed result, or nudge the real answer up or down by a percentage or an amount. Your friend types any calculation, presses =, and sees your number. The formula stays on screen, so it looks completely real.

Tricks built in:
• Change after =: type a new number within 3 seconds after = and it quietly replaces the result
• Quick +1 / −1 on the result, with the formula still shown
• Edit any formula or result in the history with a long press
• Pressing = again keeps the previous formula on screen

Also a real everyday calculator: scientific mode, unit converter (length, area, temperature, volume, mass, data, speed, time) and a tip calculator with bill splitting.

20 languages. Light, dark or device theme. No ads. Works offline.

Free: every feature. A modified result shows a small bouncing red “!” that reveals the true result when tapped. Premium removes that mark: US$4.99 once, or US$0.99 per month. The mark can be turned back on anytime.

For fun and pranks only. Never use it to deceive anyone in an exam, a transaction or any situation where an accurate result matters.
A normal-looking calculator that shows the answer you choose. Perfect prank!
