Canvas Calculator

CalcCanvas is a basic and scientific calculator that looks the way you want it to — not the way the manufacturer decided. Every calculator does the math the same way. CalcCanvas is the one you can actually make yours. WHAT IT DOES • Basic arithmetic and a full scientific mode (sin/cos/tan and inverses, log, ln, powers, roots, factorial, π, e, and more) • Degree/radian toggle • Calculation history • Handles edge cases gracefully — division by zero, malformed input, huge factorials — nothing crashes, it just tells you MAKE IT YOURS • Set any photo from your gallery as the calculator's background, with adjustable blur • Or pick from built-in gradient presets • Choose button shape: round, square, squircle, or pill • Recolor number, operator, scientific, and equals buttons independently • Adjust button opacity for a glass effect • Pick your font and size • Save your look, or jump between built-in presets (Dark Pro, Neon, Minimal, Ocean) PRIVATE BY DESIGN CalcCanvas does exactly one thing and asks for exactly one permission. There's no account, no ads, no analytics, and no network access at all — everything runs and stays on your device. Your calculations are yours; we never see them. Whether you want a calculator that matches your wallpaper or one built for late-night studying, CalcCanvas adapts to you.
