Verdict

The call

ICD 9 and ICD 10 Coding Guide both sit at 4.3 stars, but that hides the real split: 93% of ICD 9's written reviews are positive against 17% of ICD 10 Coding Guide's. ICD 9 also leads on in-app purchases (none vs 1) and update cadence (every 5 weeks vs every 11 months). ICD 10 Coding Guide's advantage is ratings volume (167 vs 22). On price, rating, ads and device support there is nothing between them.
