Verdict

The call

The clearest difference is price: Comet at Free against Odysseus's $2.99. Comet also leads on ratings volume (7.8K vs 1) and review sentiment (65% vs 50%). Odysseus's advantage is in-app purchases (none vs 3) and rating (5.0 vs 4.7). On update cadence, ads, device support and iOS requirement 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: Comet has 7.8K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 65% of Comet'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

Comet ships an update every 8 days, Odysseus weekly. Both last shipped on November 10, 2026.
