Great app, but developers are greedy f*cks.

The app itself is great and shows step by step how to solve, however the fact that it only allows you to solve 4 problems before asking to pay $3.99 for "premium" is exactly why it doesnt deserve a good rating. If you want a GOOD and COMPLETELY FREE math solver app, this isnt it.
