# Strongbox vs Synctrain

The clearest difference is in-app purchases: Synctrain at none against Strongbox's 15. Synctrain also leads on rating (4.9 vs 4.7). Strongbox's advantage is ratings volume (4.1K vs 123) and update cadence (fortnightly vs every 6 weeks). On price, review sentiment and ads there is nothing between them.

Both are free to download. Strongbox sells 14 in-app purchases, starting at $2.99 per month. Synctrain asks for nothing beyond the download.

Synctrain holds the better App Store score, 4.9 against 4.7. That said, the two scores are not equally well evidenced: Strongbox has 4.1K ratings behind it against 123, so its average is the more settled of the two. Written reviews point the same way: 84% of Strongbox's written reviews are positive against 89% of Synctrain's.

Strongbox ships an update fortnightly, Synctrain every 6 weeks. The most recent releases landed on October 17, 2026 and October 15, 2026 respectively.
