Verdict

The call

The clearest difference is price: ntfy at Free against Odysseus's $2.99. ntfy also leads on review sentiment (79% vs 50%) and ratings volume (483 vs 1). Odysseus's advantage is rating (5.0 vs 4.7) and update cadence (every 6 days vs fortnightly). On ads, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Odysseus holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: ntfy has 483 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 79% of ntfy's written reviews are positive against 50% of Odysseus's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ntfy ships an update fortnightly, Odysseus every 6 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
