App Doesn’t work

I paid and the app still doesn’t work.

Premium Modules Don’t Work

Had this app for year and development length calculator worked great. Then, I couldn’t access it and could buy another. After buying new phone, I was able to purchase premium app again. But after purchasing, it still doesn’t work

Useless App because you can’t sign in

The app requires separate account from the web version and if you try to create a sign in at the app then none of the buttons work and you can’t make an account. Giving up after trying so many times.

Sign-in

Why would this app start with a sign-in screen? The information it provides to the user does not depend on who that user is. Are they trying to track me? I just choose “guest,” but that is still an extra click before I see what I came for.

Also, the text of that sign-in page overflows to both the left and right sides of my small screen, so you can tell they just tested the app on more capable hardware. Other than those complaints, it performs as advertised.
