Verdict

The call

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.
