MyCal: Editable Calculator

MyCal is an editable scientific calculator with a built-in equation solver and step-by-step working shown. Unlike a regular calculator app, every line stays editable — change a number and every result that depended on it updates instantly. Perfect for math homework, algebra, physics, budgets, and anything where you redo the same calculation over and over.

🔢 EDITABLE LINES — THE FEATURE OTHER CALCULATORS DON'T HAVE

Type a calculation. Change any earlier number. Every result that depended on it updates live. No more restarting from scratch when you mistype one digit. This is the calculator with history that actually lets you edit history.

🔗 LINE REFERENCES (#1, #2, #3)

Use #1, #2, #3 to plug an earlier result into a later expression. Your math reads like a story, not a stream of disconnected entries.

📐 EQUATION SOLVER WITH STEP-BY-STEP WORKING

Write equations with x, y, and z — MyCal solves them and shows the work. Linear systems get full row operations laid out like a textbook would write them. Tap "See how this was solved" for the textbook walkthrough. Perfect for algebra homework and "two equations, two unknowns" problems.

📊 FULL SCIENTIFIC KEYPAD

sin, cos, tan, arcsin, arccos, arctan, log, ln, square roots, powers, factorials, π, e. Everything a scientific calculator has, plus all the things a normal scientific calculator doesn't: editable lines, equation solving, saved sheets. Switch between Basic, Scientific, and Variables modes with one tap.

💾 SAVE AND REVISIT YOUR MATH

Save any calculation to History. Come back days later, tap to load, keep editing where you left off. The calculator with notes you actually wanted.

📤 SHARE AS IMAGE

Export a beautifully formatted card of your calculation and share it anywhere — Messages, Mail, social, anywhere you can paste an image.

🎨 18+ STUNNING THEMES

Aurora, Cosmos, Sakura, Cyberpunk, Onyx Gold, Lava, Glacier, Vaporwave, Mint, Sunset, Forest, Cherry, Lavender, Neon, Ocean, Midnight, Paper, Mono. Or use your own photo as a custom background. A scientific calculator that finally looks how you want it to.

🎯 ANYONE who's ever typed the same calculation three times because of one typo.

— WHY MYCAL IS DIFFERENT —

Most calculator apps make you redo everything when you change a number. MyCal doesn't. Most scientific calculators don't solve equations. MyCal does. Most equation solvers don't show the work. MyCal walks you through it. And none of the others let you save the whole calculation sheet and edit it later.
