From a quick percentage to a compound-interest growth chart, Calculator Suite gives you 25+ specialized tools — beautifully designed, fully offline, and free of clutter.
Organized so you can find the right calculator in two taps. Search every tool from the home screen, pin your favorites, and recents appear automatically.
Basic with proper operator precedence, plus a scientific mode (sin, cos, tan, log, ln, powers, parentheses, π and e).
Six dedicated tools: X% of Y, X is what % of Y, increase / decrease, sequential discounts, ratio to %, fraction to %.
Tip, discount, discount stacking, tax, simple and compound interest with growth chart, loan with full amortization.
Unit (length / weight / temperature / volume / area), cooking, currency (offline-cached), and number base (dec / bin / hex).
Split-bill, BMI, body composition (BMR / TDEE / ideal weight), GPA, age, date difference, fuel efficiency.
Salary breakdown (gross to net, hourly, daily, weekly, monthly, annual) and subscription cost per day / week / month / year.
Every tool is independently designed — not just a skin over a generic engine.
Calculator Suite is built around the way you actually use a calculator — fast input, sensible defaults, save what matters, forget the rest.
Type what you need from the home screen — "loan", "BMI", "discount" — and jump straight in.
Pin your most-used calculators as a top row. Recents appear automatically below.
Tap any history row to jump back into its source. Save and name calculations like "My car loan".
Send any result through the Android share sheet — Slack, WhatsApp, email, anywhere.
Your last calculation, glanceable on the home screen. No need to open the app.
Switch theme from the toolbar. Tuned for phones and tablets with Material 3.
Calculator Suite works entirely offline. Your calculations never leave your device — including the currency rate you enter, your saved loans, and your salary breakdowns.
History, saved calculations and preferences are stored locally and never uploaded.
No tracking SDKs, no usage telemetry. We can't see how you use the app — that's the point.
Free, no ads, no in-app purchases. Funded by the studio as a utility for everyone.
