# Glow Glow vs O

The clearest difference is in-app purchases: Glow Glow at none against O's 1. Glow Glow also leads on ads (none vs shown) and review sentiment (95% vs 72%). O's advantage is ratings volume (191 vs 16). On price, update cadence, device support and iOS requirement there is nothing between them.

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

Glow Glow holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: O has 191 ratings behind it against 16, so its average is the more settled of the two.
