# Turtle Universe vs KingDrawHD

The clearest difference is rating: Turtle Universe at 4.6 against KingDrawHD's 4.1. Turtle Universe also leads on in-app purchases (none vs 9) and device support (3 vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. KingDrawHD sells 8 in-app purchases, starting at $1.99 per month. Turtle Universe asks for nothing beyond the download.

Turtle Universe holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 52 and 14 respectively. Written reviews complicate that: 67% of Turtle Universe's written reviews are positive against 73% of KingDrawHD's, so the app with the better star average is not the one people write more warmly about.

Turtle Universe ships an update every 6 weeks, KingDrawHD monthly. Both last shipped on October 24, 2026.
