# RPM vs Discogs

The clearest difference is in-app purchases: Discogs at none against RPM's 1. Discogs also leads on ads (none vs shown) and rating (4.8 vs 4.4). RPM's advantage is review sentiment (51% vs 40%) and iOS requirement (13.1 vs 17.0). On price, monetization model and device support there is nothing between them.

Both are free to download. RPM sells 1 one-off in-app purchase. Discogs asks for nothing beyond the download.

Discogs holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Discogs has 67K ratings behind it against 1.7K, so its average is the more settled of the two. Written reviews complicate that: 51% of RPM's written reviews are positive against 40% of Discogs's, so the app with the better star average is not the one people write more warmly about.

RPM ships an update every 2 months, Discogs every 3 weeks. The most recent releases landed on November 1, 2026 and November 5, 2026 respectively.
