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 any number and every result that depended on it updates instantly. Perfect for math homework, algebra, physics, budgets, and repeated calculations.

🔢 EDITABLE LINES — THE FEATURE OTHER CALCULATORS DON'T HAVE
Type a calculation, then go back and change any earlier number. Every result that depended on it recalculates live. No more starting over when you mistype one digit — it's the calculator with history that actually lets you edit history, a multi-line calculator that works the way you think.

🔗 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 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 full 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 what a normal one doesn't: editable lines, equation solving, and 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, and keep editing where you left off. The calculator with notes you always wanted.

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

🎨 18+ STUNNING THEMES
Aurora, Cosmos, Sakura, Cyberpunk, Neon, Ocean, Midnight, and more — or use your own photo as a custom background.
