About this app

Have you ever wanted to predict the future, read someone's mind, or pull off the perfect magic trick using just your phone?

Calculatrix is the ultimate magician’s utility tool, perfectly disguised as a sleek, fully functional everyday calculator. To anyone else, it’s just a normal app. They can add, subtract, multiply, and even use advanced scientific functions. The math will always be 100% correct. But you hold the secret to an impossible illusion.

THE EFFECT:
You hand your phone to a spectator and ask them to type in random numbers. They can multiply their birth year, divide by a random digit, add their favorite number... the math is totally real and the answers are random. But when the time is right, their final calculation will equal exactly the number you predicted before the trick even began!

ENDLESS POSSIBILITIES:
Force any custom number: Predict a PIN code, a serial number, a lottery ticket, or a special date.

Dynamic Time Force: Automatically force the current real-time clock (e.g., 10:42) without having to set it beforehand!

Dynamic Date Force: Automatically force today's exact date.

Mentalism & Stage Magic: Perfect for close-up street magic, party tricks, or stage predictions.

A FLAWLESS DISGUISE:
Calculatrix is designed to withstand the closest scrutiny.

Features a working, beautifully designed scientific calculator popup (ƒx) so it holds up even for complex math.

Native app feel: Supports swipe-to-delete, haptic feedback, and even native long-press "Copy" functionality.

Completely clean ending: The app leaves no trace of the trick once the magic happens.

HOW TO GET STARTED (READ THIS!):
