# CPT QuickRef vs CDI+

The clearest difference is review sentiment: CDI+ at 100% against CPT QuickRef's 11%. CDI+ also leads on rating (5.0 vs 4.3) and in-app purchases (none vs 12). CPT QuickRef's advantage is ratings volume (365 vs 1) and update cadence (every 6 weeks vs every 4 months). On price, ads and device support there is nothing between them.

Both are free to download. CPT QuickRef sells 12 one-off in-app purchases. CDI+ asks for nothing beyond the download.

CDI+ holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: CPT QuickRef has 365 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 11% of CPT QuickRef's written reviews are positive against 100% of CDI+'s.

CPT QuickRef ships an update every 6 weeks, CDI+ every 4 months. The most recent releases landed on October 7, 2026 and September 30, 2026 respectively.
