# Sync vs Combinations

The clearest difference is price: Combinations at Free against Sync's $0.99. Combinations also leads on update cadence (every 2 months vs every 40 months) and iOS requirement (8.0 vs 12.0). Sync's advantage is in-app purchases (none vs 1) and rating (4.8 vs 4.6). On review sentiment, ratings volume, ads and device support there is nothing between them.

Combinations is free to download; Sync costs $0.99 up front. Combinations sells 1 one-off in-app purchase. Sync asks for nothing beyond the download.

Sync holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 33 and 39 respectively. Written reviews complicate that: 97% of Sync's written reviews are positive against 98% of Combinations's, so the app with the better star average is not the one people write more warmly about.

Sync ships an update every 40 months, Combinations every 2 months. The most recent releases landed on September 10, 2026 and September 19, 2026 respectively.
