# Comet vs Euvola

The clearest difference is rating: Comet at 4.7 against Euvola's 4.0. Comet also leads on ratings volume (7.8K vs 3). Euvola's advantage is in-app purchases (none vs 3) and review sentiment (86% vs 65%). On price, update cadence, 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. Euvola asks for nothing beyond the download.

Comet holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Comet has 7.8K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 65% of Comet's written reviews are positive against 86% of Euvola's, so the app with the better star average is not the one people write more warmly about.

Comet ships an update every 8 days, Euvola weekly. The most recent releases landed on November 11, 2026 and October 30, 2026 respectively.
