# Liquid Apollo vs Comet

The clearest difference is in-app purchases: Liquid Apollo at none against Comet's 3. Comet's advantage is rating (4.8 vs 4.5) and ratings volume (7.8K vs 653). On price, review sentiment, update cadence and ads there is nothing between them.

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

Comet holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Comet has 7.8K ratings behind it against 653, so its average is the more settled of the two. Written reviews complicate that: 68% of Liquid Apollo's written reviews are positive against 65% of Comet'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, Comet weekly. The most recent releases landed on October 18, 2026 and October 20, 2026 respectively.
