# Knock Out vs Gloop Jelly

The clearest difference is review sentiment: Gloop Jelly at 100% against Knock Out's 50%. Gloop Jelly also leads on rating (5.0 vs 4.8) and monetization model (ad-supported vs free with in-app purchases). Knock Out's advantage is ads (none vs shown) and ratings volume (38K vs 1). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Knock Out sells 10 one-off in-app purchases and Gloop Jelly sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Gloop Jelly holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Knock Out has 38K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 50% of Knock Out's written reviews are positive against 100% of Gloop Jelly's.

Knock Out ships an update every 4 days, Gloop Jelly every 3 weeks. The most recent releases landed on November 11, 2026 and October 31, 2026 respectively.
