NovaCalc – Smart Calculator

One free app for every calculation — loans, BMI, tips, currency and more. Each result comes with a clear, plain-English explanation. Works offline. No ads, ever.

NovaCalc is an all-in-one calculator that actually explains its answers. Instead of just showing a number, it tells you what the number means in plain English — with charts and shareable reports. Everything works offline, for free, with no ads and no account.

SEVEN TOOLKITS IN ONE APP

• Finance — loan & mortgage payments, compound interest, savings goals, ROI, income tax, break-even
• Health — BMI, body fat, daily calories, water intake, due date, ovulation
• Construction — paint, tiles, flooring, wallpaper, concrete estimates
• Converters — units and live currency exchange
• Everyday — tips, discounts, percentages
• Date & Time — age, date differences
• Vehicle — fuel cost and fuel economy Plus a fast basic & scientific calculator with history.

UNDERSTAND EVERY RESULT Each calculator gives you more than a figure: a clear explanation of what it means, growth and breakdown charts, and a detailed report (like a year-by-year loan amortization schedule) you can export to PDF and share.

PRIVATE BY DESIGN NovaCalc runs on your device. There are no accounts, no ads, and no tracking. It works fully offline. Currency rates are the only thing fetched from the internet, and only when you open the converter.

OPTIONAL AI EXPLANATIONS — YOUR CHOICE Want a friendlier, AI-written take on your numbers? Turn on on-device AI (Apple Intelligence, where available) for fully private explanations — or bring your own API key from OpenAI, Anthropic, Google, and others. It's off by default; the app is fully useful without it.
