# Cylinder vs Flatify

The clearest difference is rating: Cylinder at 2.1 against Flatify's 1.0. Cylinder also leads on in-app purchases (none vs 3) and ratings volume (12 vs 1). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Flatify sells 3 in-app purchases, starting at $8.99 per month. Cylinder asks for nothing beyond the download.

Cylinder holds the better App Store score, 2.1 against 1.0. That said, the two scores are not equally well evidenced: Cylinder has 12 ratings behind it against 1, so its average is the more settled of the two.
