# Sina vs GlowAlign

The clearest difference is in-app purchases: GlowAlign at none against Sina's 1. GlowAlign also leads on rating (5.0 vs 4.5) and update cadence (every 2 days vs every 3 weeks). Sina's advantage is ratings volume (134 vs 1). On price, 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. GlowAlign asks for nothing beyond the download.

GlowAlign holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Sina has 134 ratings behind it against 1, so its average is the more settled of the two.

Sina ships an update every 3 weeks, GlowAlign every 2 days. The most recent releases landed on October 25, 2026 and October 12, 2026 respectively.
