# NUMS vs CodeAB

The clearest difference is review sentiment: CodeAB at 100% against NUMS's 55%. CodeAB also leads on rating (5.0 vs 4.1) and ads (none vs shown). NUMS's advantage is in-app purchases (none vs 1) and ratings volume (15 vs 3). On price and device support there is nothing between them.
