# Mattermost vs GAM

The clearest difference is review sentiment: GAM at 75% against Mattermost's 38%. GAM also leads on rating (5.0 vs 4.8) and iOS requirement (15.1 vs 18.0). Mattermost's advantage is update cadence (every 9 days vs every 4 months) and ratings volume (5.7K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

GAM holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Mattermost has 5.7K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 38% of Mattermost's written reviews are positive against 75% of GAM's.

Mattermost ships an update every 9 days, GAM every 4 months. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
