OffOf — Simple Percentage Calculator App
Offof is a really simple percentage calculator app for iPhone. It has a really straightforward UI and is reall simple to use. If you’ve ever gotten confused trying to calculate the percentage of any given number, this is the app you’ve always wished you had.
Offof lets you quickly calculate the percentage value either Off (subtracted) an entered value or the percentage value Of an entered value. The former is really helpful when you’re out shopping and come across a sale at any store. 30% off on your favorite boots that cost $500? Just whip out Offoff, enter 30% at the top and the amount as 500 — the app will tell you exactly how much you need to pay. Toggle the switch from OFF to OF and you now have the amount you’ve actually saved from this sale. It really doesn’t get simpler than this. I wish there was a quick ‘Clear All’ button in the app though.
OffOf is available Free on the App Store
