Verdict
The clearest difference is in-app purchases: Keep Contacts at none against A2Z Groups's 5. Keep Contacts also leads on rating (5.0 vs 4.6). A2Z Groups's advantage is review sentiment (82% vs 50%) and ratings volume (3.9K vs 1). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. A2Z Groups sells 4 in-app purchases, starting at $0.99 per year. Keep Contacts asks for nothing beyond the download.
Keep Contacts holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: A2Z Groups has 3.9K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Keep Contacts's written reviews are positive against 82% of A2Z Groups's, so the app with the better star average is not the one people write more warmly about.
Keep Contacts ships an update every 6 weeks, A2Z Groups every 3 weeks. The most recent releases landed on September 20, 2026 and September 24, 2026 respectively.
