# H2O vs Gains Chat

The clearest difference is in-app purchases: Gains Chat at none against H2O's 6. Gains Chat also leads on rating (5.0 vs 4.5) and iOS requirement (15.1 vs 26.0). H2O's advantage is ratings volume (175 vs 6). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. H2O sells 4 in-app purchases, starting at $1.99 per month. Gains Chat asks for nothing beyond the download.

Gains Chat holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: H2O has 175 ratings behind it against 6, so its average is the more settled of the two.
