# ICD9 On the Go vs CPT QuickRef

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.

Both are free to download. ICD9 On the Go sells 1 one-off in-app purchase and CPT QuickRef sells 12 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.4 for ICD9 On the Go against 4.3 for CPT QuickRef. That said, the two scores are not equally well evidenced: CPT QuickRef has 366 ratings behind it against 42, so its average is the more settled of the two.
