Too many annoyances.

There are many issues with this app:

1. It has been unresponsive to me for months. It keeps showing that I have to wait numerous hours until I can use it again.
2. The few minutes that I once got every 9 or so hours were never enough.
3. The cost to buy a few minutes is ridiculously high... Im not sure why you would bother.
4. You could spend more time watching ads than learning.
