# ntfy vs Comet

The clearest difference is in-app purchases: ntfy at none against Comet's 3. ntfy also leads on review sentiment (79% vs 65%) and iOS requirement (15.0 vs 18.0). Comet's advantage is ratings volume (7.8K vs 474) and update cadence (weekly vs fortnightly). On price, rating, ads and device support there is nothing between them.

Both are free to download. Comet sells 3 in-app purchases, starting at $20.00 per month. ntfy asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.8 for ntfy against 4.7 for Comet. That said, the two scores are not equally well evidenced: Comet has 7.8K ratings behind it against 474, so its average is the more settled of the two. Written reviews are what separate them: 79% of ntfy's written reviews are positive against 65% of Comet's.

ntfy ships an update fortnightly, Comet weekly. Both last shipped on October 25, 2026.
