Was great, now it’s decent when it works

When I first started using the app it was great. Now after recently updating to iOS 12, it is super buggy. It freezes and force closes all the time. Hopefully this will be fixed soon

Great and useful

This is great. It could be even better if it automatically showed the final price (calculated discount minus original price) as well so I don't have to do any math at all. Also taping into a field should auto clear it and let me type a new number instead of having to backspace the old number.

Simple and Practical

Love this app. It focuses on one thing and does it well. Very handy for figuring out percents and prices on the fly. Only wish would be that tapping the previous amount or percent would clear the field so you don’t have to manually backspace each one for new entries.
