Charged me again

I bought the app. Then they decided to change it and made me pay for it again or it would be work and now I got the new iPhone pro max and the current version ( I paid twice for ) won’t even work and I can’t use it AGAIN. Do better for frig sake. Stop making the ppl who pay you do without quality service and pay you again. It should just work. It should just cost one time only. I’ll find another calculator app to use!!!

Sounds stopped working after last update.

No sounds, no haptic feedback on iPhone 6s when using the calculator.
