Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
