USELESS

Need to pay before you use.

The text is cropped and I cannot read it properly. Please fix this

I cant read the courses and i cant also zoom out

Good app; needs update to accommodate newer phone screens

I can’t hit back or contents buttons on iPhone 13 because it appears app is designed for older notchless screens

annoying pop up

I love the app, but every time i click anything a pop up tells me to buy the plus version. I am not going to do that.
