Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Instant result previews, a handy Copy button and M memory. Plot two functions and explore values, roots and intersections.
Keep scientific calculation clear and close at hand. Eqnora puts large keys, DEG/RAD, results and recent calculations on one screen. Unit conversion, number bases, decimal-to-fraction conversion, coordinates and scientific constants are free.
An optional, one-time Lifetime Pro purchase unlocks equations, matrices, numerical calculus, two-function graphs, statistics and electrical tools, and removes ads. The free calculator remains available without a purchase. You can also choose to watch one rewarded ad to get a free 1-hour Pro pass. It activates when the reward is granted, with all Pro features and no ads. No payment or automatic subscription. Calculation history stays on your device.
Pro: Save formulas by name, with their variable values. Vary one input and compare up to 101 results.
