There's a glitch in the Android version where it won't show a detail. (letter or number)
I recommend this app to each of my algebra students to begin to do mental algebra. Great app. Well designed!
Probably the best all-around math app we have. Installed everything from the developer.
Excellent Let's you think through your algebra problems explicitly with instant feedback.
This app sucks There is not much you can do. Not worth paying for this app.
Ready for release!
