### 2/5 — Used to be free, now a subscription?

*2026-08-24, version 9.27.0*

I’ve used this for years, thinking it was Apple’s calculator. Odd they never made one before iOS 18 for the iPad. I can deal with ads on the free version. Now I get notices I need to sign up for a subscription? No thank you. I understand wanting to make a buck or two, but it’s a calculator.  Ads it is.

### 1/5 — Waste of time

*2026-08-17, version 9.27.0*

This app is trash… I’m tired of dealing with apps that basically force you to pay for a subscription for no ads. I couldn’t even use the calculator because anytime I tried to press a number their subscription screen would pop up. I chose no time after time and still could not get rid of the screen basically telling me that in order to use the app, I have to purchase a subscription. The app is being deleted. It is unusable and a waste of time to even download

### 1/5 — Why not?

*2026-08-16, version 9.27.0*

Why isnt there a cash option to auto put the decimal point???

### 5/5 — Calculator

*2026-08-14, version 9.27.0*
