Doesn't work like an abacus!! – Early Learning Abacus Review
This app counts every bead as one! It makes no use of place value, which is the purpose of using an abacus! If I move one bead on the bottom row and one bead on the second bottom row, that should represent eleven. Instead, this app calls it two. No use if you actually want an abacus, unless you ignore the counter at the top.
