Verdict

The call

The clearest difference is rating: Mattermost at 4.8 against NanoWatch's 3.3. Mattermost also leads on update cadence (every 8 days vs every 2 months) and ratings volume (5.6K vs 18). NanoWatch's advantage is review sentiment (50% vs 38%) and iOS requirement (9.0 vs 16.0). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Mattermost holds the better App Store score, 4.8 against 3.3. That said, the two scores are not equally well evidenced: Mattermost has 5.6K ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 38% of Mattermost's written reviews are positive against 50% of NanoWatch's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Mattermost ships an update every 8 days, NanoWatch every 2 months. The most recent releases landed on September 25, 2026 and June 1, 2026 respectively.
