Verdict

The call

The clearest difference is in-app purchases: iContacts at none against Customer Database's 8. iContacts also leads on ratings volume (289 vs 47) and review sentiment (67% vs 58%). Customer Database's advantage is ads (none vs shown) and iOS requirement (13.0 vs 17.0). On price, rating, update cadence and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Customer Database holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: iContacts has 289 ratings behind it against 47, so its average is the more settled of the two. Written reviews complicate that: 67% of iContacts's written reviews are positive against 58% of Customer Database's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iContacts ships an update every 4 weeks, Customer Database every 3 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
