Ratings and reviews

Undoubtly Geogebra doesn't need further presentations, and this is probably the best CAS you can install on a mobile (if you need do more serious things, turn on computer and, Geogebra is not renamed as a CAS for professional mathematicians) , HOWEVER, I dislike so much that is almost disappeared the possibility to save offline the own works. Come on guys, this is a mobile app, it is not used for making reasoned works to share online, I use it while playing at racing games XD

Frustrating. I try to save what I have without signing up. Doesn't work. I try making an account with my Google account. Account seems to be made. I go back to the app, it tells me to sign in. I try signing in with Google, it tells me I need to sign up. Wth. Everything else works great, but considering how much time it takes to input things, being able to save formulas is a must.

The backspace button deletes everything before the cursor unless tapped again. It's like an on-off toggle instead of just a one character backspace. It makes it super frustrating to correct a mistake, because if you don't time it right, you delete way more than you expected. (Emailed details, it's great otherwise!)
