# E/M Coder vs CredBook

The clearest difference is rating: CredBook at 5.0 against E/M Coder's 4.0. CredBook also leads on update cadence (every 2 days vs every 2 weeks). E/M Coder's advantage is in-app purchases (none vs 2) and ratings volume (8 vs 1). On price, ads and device support there is nothing between them.
