Horrible App

If I could I would rate this a 0 star. I paid $4.99 for this app and when I went to type a problem in it said I needed a premium subscription. I am already paying for the app and now I need to pay more? How does that add up? *no pun intended* If you are looking at purchasing this app, DONT. Waist of money and doesnt do well at solving problems. Take my advice and find a better math solver.
