# iPacemaker Device vs CareLink SmartSync™ US

The clearest difference is rating: iPacemaker Device at 4.7 against CareLink SmartSync™ US's 3.8. iPacemaker Device also leads on update cadence (every 4 days vs every 4 months) and ratings volume (365 vs 16). CareLink SmartSync™ US's advantage is in-app purchases (none vs 7) and review sentiment (50% vs 28%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. iPacemaker Device sells 7 in-app purchases, starting at $9.99 per month. CareLink SmartSync™ US asks for nothing beyond the download.

iPacemaker Device holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: iPacemaker Device has 365 ratings behind it against 16, so its average is the more settled of the two. Written reviews complicate that: 28% of iPacemaker Device's written reviews are positive against 50% of CareLink SmartSync™ US's, so the app with the better star average is not the one people write more warmly about.

iPacemaker Device ships an update every 4 days, CareLink SmartSync™ US every 4 months. The most recent releases landed on October 10, 2026 and October 6, 2026 respectively.
