# Liquid Apollo vs Odysseus

The clearest difference is price: Liquid Apollo at Free against Odysseus's $2.99. Liquid Apollo also leads on ratings volume (664 vs 1) and review sentiment (68% vs 50%). Odysseus's advantage is rating (5.0 vs 4.5) and chart position (#94 vs unranked). On update cadence, ads, in-app purchases and device support there is nothing between them.

Liquid Apollo is free to download; Odysseus costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Odysseus holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Liquid Apollo has 664 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 68% of Liquid Apollo'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.

Liquid Apollo ships an update every 10 days, Odysseus every 6 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
