Comments on Mental Abacus Book 3 for Android

★★★★★ A Google user · Nov 15, 2019
Such an expensive app but this is the best of its field. Costed me over 50 bucks to complete entire course (3 levels and 3 training modules) I love to hands motion part, it shows how our hand should move the beard that lots of other apps doesn't have and confused me.
