OmniCalc All-in-One Calculator

OmniCalc brings 200 calculators into one app for everyday math, study, money and measurements. Use a scientific calculator, unit converter, loan calculator and practical tools for work and home. Formula calculations work offline. Currency updates use the internet; cached or manual rates remain available offline. Scientific math and graphs Edit expressions, calculate fractions, matrices and complex numbers, or explore derivatives, integrals, bracketed roots and linear regression. Plot up to three functions with value tables. Use Cartesian, polar and parametric curves or rotatable 3D surfaces, with pan, zoom, trace values and approximate intersections. Advanced Math Workbench Simplify, expand and factor expressions, calculate symbolic derivatives and integrals, and find candidate equation solutions. Keep fractions and large integers exact where supported. Choose 15–100 digit arithmetic and rounding modes. Follow worked linear/quadratic solutions and polynomial differentiation or integration. Domain checks still matter; numerical answers are approximations, not certified error bounds. Explore continuous audio graph traces, Nemeth Braille transcription and graph image export. Use persistent RPN stacks with undo and redo, nine scientific memory registers and 355 CODATA constants with units and uncertainties. Read printed text from a selected image or download the optional Google handwriting model, then correct the expression. Complex fractions and exponents may be misread. Recognition runs on-device after its model is available; Google SDK diagnostics may use the internet. Money and shopping Calculate EMI and mortgage payments, compare loans and prepayments, and read amortization schedules. Estimate compound interest, SIP growth, investment returns and savings after tax. Compare unit prices, calculate discounts, sales tax, GST or VAT, and split bills with tips that can exclude tax. Units and everyday tools Convert measurements, currencies, combined feet/inches and DMS angles. Compare regional cooking volumes and defined land units, convert ingredient quantities with your own density, or consult a clearly identified shoe-size chart. Calculate dates, time zones, GPA, attendance, fuel costs, recipes and construction quantities. Health tools include BMI, BMR and cycle-date estimates; cycle dates are not for contraception. Keep useful results Use the home-screen widget, favorites, annotated history, copy/share and CSV/PDF export. Choose light or dark themes and phone, tablet or landscape layouts. On Android 8+, save password-encrypted library backups locally or through a file provider such as Google Drive. Workbench has a separate readable JSON export. There is no automatic cloud sync. Inputs and history stay on your device unless you export or share them. Ads and an optional one-time ad-removal purchase are included. Analytics and ad privacy controls are in Settings. Financial, health, tax and construction results are general estimates, not professional advice. Verify important results. Some interface translations use Google Translate via ML Kit.
