# Blue Block vs Flow Free

The clearest difference is rating: Flow Free at 4.8 against Blue Block's 4.1. Flow Free also leads on ratings volume (10K vs 47) and device support (3 vs 1). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Blue Block sells 2 one-off in-app purchases and Flow Free sells 11 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Flow Free holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Flow Free has 10K ratings behind it against 47, so its average is the more settled of the two. Written reviews point the same way: 80% of Blue Block's written reviews are positive against 84% of Flow Free's.

Both ship on a similar rhythm, roughly every 5 months. The most recent releases landed on September 23, 2026 and October 15, 2026 respectively.
