# Orbit vs Block Stack

The clearest difference is in-app purchases: Block Stack at none against Orbit's 7. Block Stack also leads on update cadence (every 10 days vs every 2 months) and rating (5.0 vs 4.8). Orbit's advantage is ratings volume (7.6K vs 3) and device support (3 vs 1). On price, review sentiment, ads and iOS requirement there is nothing between them.

Both are free to download. Orbit sells 7 one-off in-app purchases. Block Stack asks for nothing beyond the download.

Block Stack holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Orbit has 7.6K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 94% of Orbit's written reviews are positive against 100% of Block Stack's.

Orbit ships an update every 2 months, Block Stack every 10 days. The most recent releases landed on October 1, 2026 and September 12, 2026 respectively.
