Ratings and reviews

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!)

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.

This is the best algebra solver on the play store! No ads, and works offline! I wish i could turn off the grid entirely, it eats up a lot of screen realty. I don't care about graphing, just solving equations. A dark theme would be nice.
