# RMU Mobile vs RedShelf

The clearest difference is review sentiment: RMU Mobile at 57% against RedShelf's 3%. RedShelf's advantage is rating (4.5 vs 2.3) and ratings volume (7.1K vs 4). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

RedShelf holds the better App Store score, 4.5 against 2.3. That said, the two scores are not equally well evidenced: RedShelf has 7.1K ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 57% of RMU Mobile's written reviews are positive against 3% of RedShelf's, so the app with the better star average is not the one people write more warmly about.

RMU Mobile ships an update every 5 months, RedShelf every 5 weeks. The most recent releases landed on October 9, 2026 and October 16, 2026 respectively.
