Good but function problems
First, the good points:
1) Free.
2) All of the tefilos are clear and easy to scroll.
3) lots of options of nusach.
4) Easy to use.
Now, for the most glaring aspect missing:
There is no way to increase the font size, and the current size is pretty small. I am not that old and I found it straining my eyes.
