# OpenCat vs Cumbersome

The clearest difference is monetization model: Cumbersome at free against OpenCat's free with in-app purchases. Cumbersome also leads on review sentiment (88% vs 65%) and rating (4.9 vs 4.6). OpenCat's advantage is ratings volume (851 vs 97). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. OpenCat sells 4 in-app purchases, starting at $3.99 per month and Cumbersome sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

Cumbersome holds the better App Store score, 4.9 against 4.6. That said, the two scores are not equally well evidenced: OpenCat has 851 ratings behind it against 97, so its average is the more settled of the two. Written reviews point the same way: 65% of OpenCat's written reviews are positive against 88% of Cumbersome's.

OpenCat ships an update weekly, Cumbersome every 3 days. Both last shipped on October 25, 2026.
