About 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.
