Oalculator

Oalculator is a retro-style calculator, with a typewriter on iPhone Duo. Round keys and a seven-segment display, with memory keys, percent, percent change and square root. It follows your light or dark setting. MADE FOR IPHONE DUO • On the inner display, a typewriter prints each sum on a sheet of paper. • Tear the sheet off when you're done. It goes into an archive you can flip through. • Every sheet has a line for you on its back. Turn it over to read it. • Keep the ones that matter. Save or share either side as an image. The typewriter needs the inner display of iPhone Duo; other iPhones don't have it. PRIVACY Everything stays on your device. No account, no servers, no analytics, no ads.
