# Clicka! vs Under Up

The clearest difference is ads: Clicka! at none against Under Up's shown. Clicka! also leads on monetization model (free vs free with in-app purchases) and ratings volume (2.9K vs 1). Under Up's advantage is rating (5.0 vs 4.7) and update cadence (every 3 days vs every 8 days). On price, review sentiment, in-app purchases and device support there is nothing between them.

Both are free to download. Clicka! sells 2 one-off in-app purchases and Under Up sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Under Up holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Clicka! has 2.9K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 95% of Clicka!'s written reviews are positive against 100% of Under Up's.

Clicka! ships an update every 8 days, Under Up every 3 days. The most recent releases landed on October 21, 2026 and October 2, 2026 respectively.
