# Contacts Sync vs Easy Caller ID

The clearest difference is in-app purchases: Easy Caller ID at none against Contacts Sync's 7. Contacts Sync's advantage is update cadence (every 5 days vs every 2 months) and rating (4.6 vs 4.3). On price, ads and device support there is nothing between them.

Both are free to download. Contacts Sync sells 7 in-app purchases, starting at $1.99 per 7 days. Easy Caller ID asks for nothing beyond the download.

Contacts Sync holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Contacts Sync has 15K ratings behind it against 2.7K, so its average is the more settled of the two. Written reviews point the same way: 80% of Contacts Sync's written reviews are positive against 69% of Easy Caller ID's.

Contacts Sync ships an update every 5 days, Easy Caller ID every 2 months. The most recent releases landed on November 10, 2026 and November 7, 2026 respectively.
