Verdict
The clearest difference is rating: MarinDeck at 3.7 against Rium's 2.9. MarinDeck also leads on in-app purchases (none vs 10). Rium's advantage is review sentiment (67% vs 44%) and update cadence (every 9 days vs every 3 weeks). On price, ratings volume, ads and device support there is nothing between them.

Both are free to download. Rium sells 10 one-off in-app purchases. MarinDeck asks for nothing beyond the download.
MarinDeck holds the better App Store score, 3.7 against 2.9. Both are backed by a comparable volume of ratings — 10 and 8 respectively. Written reviews complicate that: 44% of MarinDeck's written reviews are positive against 67% of Rium's, so the app with the better star average is not the one people write more warmly about.
MarinDeck ships an update every 3 weeks, Rium every 9 days. The most recent releases landed on October 15, 2026 and October 14, 2026 respectively.
