# Dyslock vs Under Up

The clearest difference is update cadence: Under Up at every 3 days against Dyslock's every 5 weeks. Under Up also leads on iOS requirement (13.0 vs 15.0). Dyslock's advantage is ratings volume (72 vs 3). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Dyslock sells 3 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 4.8. That said, the two scores are not equally well evidenced: Dyslock has 72 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Dyslock ships an update every 5 weeks, Under Up every 3 days. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
