# Deck vs Mopiq

The clearest difference is rating: Mopiq at 4.7 against Deck's 4.0. Mopiq also leads on update cadence (weekly vs every 3 months) and ratings volume (1.4K vs 4). Deck's advantage is review sentiment (100% vs 69%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Deck sells 3 in-app purchases, starting at $1.99 per 3 months and Mopiq sells 10 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Mopiq holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Mopiq has 1.4K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 100% of Deck's written reviews are positive against 69% of Mopiq's, so the app with the better star average is not the one people write more warmly about.

Deck ships an update every 3 months, Mopiq weekly. The most recent releases landed on October 9, 2026 and October 25, 2026 respectively.
