# Blue Block vs Slidey®

The clearest difference is rating: Slidey® at 4.7 against Blue Block's 4.1. Slidey® also leads on ads (none vs shown) and ratings volume (1.7K vs 48). Blue Block's advantage is review sentiment (80% vs 57%). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

Both are free to download. Blue Block sells 2 one-off in-app purchases and Slidey® sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Slidey® holds the better App Store score, 4.7 against 4.1. That said, the two scores are not equally well evidenced: Slidey® has 1.7K ratings behind it against 48, so its average is the more settled of the two. Written reviews complicate that: 80% of Blue Block's written reviews are positive against 57% of Slidey®'s, so the app with the better star average is not the one people write more warmly about.

Blue Block ships an update every 5 months, Slidey® every 2 months. The most recent releases landed on October 23, 2026 and October 29, 2026 respectively.
