# Doodle Devil™ Alchemy vs Zendoku

The clearest difference is price: Doodle Devil™ Alchemy at Free against Zendoku's $0.99. Doodle Devil™ Alchemy also leads on ratings volume (90 vs 2). Zendoku's advantage is rating (4.0 vs 2.8) and in-app purchases (none vs 10). On review sentiment, update cadence, device support and iOS requirement there is nothing between them.

Doodle Devil™ Alchemy is free to download; Zendoku costs $0.99 up front. Doodle Devil™ Alchemy sells 10 one-off in-app purchases. Zendoku asks for nothing beyond the download.

Zendoku holds the better App Store score, 4.0 against 2.8. That said, the two scores are not equally well evidenced: Doodle Devil™ Alchemy has 90 ratings behind it against 2, 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 Zendoku's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on October 21, 2026 and October 1, 2026 respectively.
