# Cumbersome vs opchat

The clearest difference is rating: Cumbersome at 4.9 against opchat's 4.0. Cumbersome also leads on ratings volume (102 vs 2) and update cadence (every 4 days vs every 2 weeks). opchat's advantage is review sentiment (100% vs 89%). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Cumbersome holds the better App Store score, 4.9 against 4.0. That said, the two scores are not equally well evidenced: Cumbersome has 102 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 89% of Cumbersome's written reviews are positive against 100% of opchat's, so the app with the better star average is not the one people write more warmly about.

Cumbersome ships an update every 4 days, opchat every 2 weeks. Both last shipped on November 9, 2026.
