# Sincey vs MyBox

The clearest difference is in-app purchases: Sincey at none against MyBox's 1. Sincey also leads on rating (5.0 vs 4.7) and update cadence (every 4 days vs every 9 days). MyBox's advantage is ratings volume (6 vs 1) and iOS requirement (18.0 vs 26.0). On price, ads and device support there is nothing between them.

Both are free to download. MyBox sells 1 one-off in-app purchase. Sincey asks for nothing beyond the download.

Sincey holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: MyBox has 6 ratings behind it against 1, so its average is the more settled of the two.

Sincey ships an update every 4 days, MyBox every 9 days. The most recent releases landed on September 28, 2026 and October 12, 2026 respectively.
