Verdict

The call

ICD9 On the Go and CPT QuickRef both sit at 4.4 stars, but that hides the real split: 92% of ICD9 On the Go's written reviews are positive against 11% of CPT QuickRef's. ICD9 On the Go also leads on iOS requirement (9.0 vs 15.1). CPT QuickRef's advantage is update cadence (every 6 weeks vs every 11 months) and chart position (#197 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.
