Love it but needs updating – Ez Shopping Calculator Review

I've had this app for a long time, its the best shopping calculator I could find. It's the only one where you can turn tax on and off, which is what I need in my state where food is not taxed. But it needs to be updated for iOS 10. Tax no longer works. Please update soon, because now I have to use two calculators, one for taxable items and one for the rest. It's annoying.
