# Carbonite Mobile vs Sync

The clearest difference is rating: Carbonite Mobile at 4.4 against Sync's 4.1. Sync's advantage is review sentiment (50% vs 37%) and update cadence (monthly vs every 3 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Carbonite Mobile holds the better App Store score, 4.4 against 4.1. Both are backed by a comparable volume of ratings — 1.1K and 805 respectively. Written reviews complicate that: 37% of Carbonite Mobile's written reviews are positive against 50% of Sync's, so the app with the better star average is not the one people write more warmly about.

Carbonite Mobile ships an update every 3 months, Sync monthly. The most recent releases landed on September 18, 2026 and September 22, 2026 respectively.
