# vitaLib vs Sina

The clearest difference is in-app purchases: vitaLib at none against Sina's 1. vitaLib also leads on iOS requirement (13.0 vs 15.6). Sina's advantage is update cadence (every 3 weeks vs every 10 months) and ratings volume (134 vs 2). On price, rating, ads and device support there is nothing between them.

Both are free to download. Sina sells 1 in-app purchase, starting at $9.99 per month. vitaLib asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.5 for vitaLib against 4.5 for Sina. That said, the two scores are not equally well evidenced: Sina has 134 ratings behind it against 2, so its average is the more settled of the two.

vitaLib ships an update every 10 months, Sina every 3 weeks. The most recent releases landed on November 4, 2026 and October 30, 2026 respectively.
