# Clicka! vs Ouroboros

The clearest difference is in-app purchases: Ouroboros at none against Clicka!'s 2. Clicka!'s advantage is ads (none vs shown) and update cadence (every 8 days vs every 5 months). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. Clicka! sells 2 one-off in-app purchases. Ouroboros asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for Clicka! against 4.6 for Ouroboros. That said, the two scores are not equally well evidenced: Clicka! has 2.9K ratings behind it against 10, so its average is the more settled of the two. Written reviews are what separate them: 95% of Clicka!'s written reviews are positive against 85% of Ouroboros's.

Clicka! ships an update every 8 days, Ouroboros every 5 months. Both last shipped on October 21, 2026.
