NOVA: Scientific calculator

Meet NOVA - the offline calculator you can make your own. Turn a formula into a reusable calculator and share it with someone else. NOVA combines a focused full-height calculator with everyday and scientific math, measurement conversion, date and finance tools, plus a no-code two-input calculator creator. SCIENTIFIC CALCULATOR • Full-height calculator without persistent title and bottom navigation. Tap ƒx for scientific keys. • Trigonometry, logarithms, square roots, powers, factorials and percentage expressions. • DEG/RAD modes, cursor-aware expression editing, decimal results and intermediate evaluation steps in an optional panel. • Share your calculation as text or as a designed image. UNIT CONVERTER • 20 categories covering 106 named units, including length, mass, speed, temperature, area, volume, energy, power, data and more. • Fast source/destination switching, precise decimal handling, and separate temperature-difference conversions. DATE & FINANCE TOOLS • Calendar differences, date shifts and weekday counting. • Compound-growth estimates, fixed-rate loan payments, gross margin and percentage change. MAKE YOUR OWN CALCULATOR • Start blank or from an example. Follow Name, Inputs, Formula and Preview. • Enter two numeric inputs, preview the result, then save and reuse it. Duplicate an existing calculator to customize it. • Share templates as importable files or share results as PNG images. • Explore built-in templates, including discounts, rectangle area, trip fuel and 3D-print material cost. PRIVATE BY DESIGN • No account required. No ads. No app-operated cloud service. • Works without internet access; formulas and custom templates stay on your device until you choose to share them. • A built-in Help guide explains the included functions and limitations. NOVA's formula solver searches for an approximate numerical root in a user-selected interval. Results of scientific functions, financial projections and certain unit conversions can be approximate. The app is a general-purpose calculator, not professional financial or medical advice.
