# Doodle Devil™ Alchemy vs Gravblock

The clearest difference is price: Doodle Devil™ Alchemy at Free against Gravblock's $0.99. Doodle Devil™ Alchemy also leads on ratings volume (90 vs 6). Gravblock's advantage is rating (4.2 vs 2.8) and ads (none vs shown). On review sentiment, update cadence, in-app purchases and device support there is nothing between them.

Doodle Devil™ Alchemy is free to download; Gravblock costs $0.99 up front. Doodle Devil™ Alchemy sells 10 one-off in-app purchases and Gravblock sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Gravblock holds the better App Store score, 4.2 against 2.8. That said, the two scores are not equally well evidenced: Doodle Devil™ Alchemy has 90 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 40% of Doodle Devil™ Alchemy's written reviews are positive against 33% of Gravblock's, so the app with the better star average is not the one people write more warmly about.

Doodle Devil™ Alchemy ships an update every 3 months, Gravblock every 6 months. The most recent releases landed on August 15, 2026 and June 7, 2026 respectively.
