Magic Calculator: Mentalism

18 calculator themes plus a builder for your own, six worked routines, and a force nobody catches. No ad ever interrupts a performance.

Magic Calculator turns your iPhone into a calculator that shows the number you choose — while working perfectly for every other sum anyone tries.

Pick a theme, set your force, and hand it over. There is nothing to notice.

18 THEMES, OR DESIGN YOUR OWN 18 calculator themes — dark and light, soft squares and ruled grids, warm minimal and neon. Or open the builder and choose every colour, key shape and layout yourself, or shuffle for a design nobody has seen.

A REAL CALCULATOR Every sum is genuinely correct. Correct operator precedence, percentages that behave the way people expect, parentheses, square root, powers and factorial. Hand it to anyone to check — it survives inspection, which is the whole point.

THE FORCE

• Fire once on the next equals, then disarm automatically
• Let them verify two or three honest sums first, then force
• Queue several numbers for a multi-phase routine
• Match decimal places so your number never looks out of place
• Only fire when the digit count is believable

SECRET TRIGGERS Arm the force without anyone seeing: a tap in a dead corner, a short rhythm of taps, a swipe across the display, one sharp shake, a hold on the decimal point, or a timer that arms itself with no touch at all.

PANIC RESET Hold the display for a second and everything clears and disarms instantly. For the moment a spectator takes the phone out of your hands.

THE PEEK Quietly remembers the last number a spectator typed, so you can reveal it ten minutes later as an afterthought.

ROUTINES INCLUDED Six worked routines with full setup and performance notes, from a beginner opener to a hands-off effect where you never touch the phone.

BUILT FOR PERFORMING Stage Mode blocks every ad for thirty minutes so nothing can interrupt you. No ad ever appears during a routine.

Free to download. Coins come free every day and from optional short videos. Coin packs and a one-time Pro upgrade (every theme, 50,000 coins, no ads) are optional.

Magic Calculator is a prop for magicians and mentalists. It is also a genuinely good calculator.
