# Drawing Studio vs Comet

The clearest difference is rating: Comet at 4.7 against Drawing Studio's 3.5. Comet also leads on ratings volume (7.8K vs 2). Drawing Studio's advantage is in-app purchases (none vs 3) and review sentiment (100% 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. Drawing Studio asks for nothing beyond the download.

Comet holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Comet has 7.8K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Drawing Studio'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.

Drawing Studio ships an update every 9 days, Comet every 8 days. The most recent releases landed on October 30, 2026 and November 9, 2026 respectively.
