# Naim Catalog vs Elecat Group

The clearest difference is rating: Naim Catalog at 5.0 against Elecat Group's 4.5. Naim Catalog also leads on in-app purchases (none vs 2) and update cadence (every 3 weeks vs every 2 months). Elecat Group's advantage is review sentiment (100% vs 83%) and ratings volume (10 vs 2). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Elecat Group sells 2 in-app purchases, starting at $99.99 per month. Naim Catalog asks for nothing beyond the download.

Naim Catalog holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Elecat Group has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 83% of Naim Catalog's written reviews are positive against 100% of Elecat Group's, so the app with the better star average is not the one people write more warmly about.

Naim Catalog ships an update every 3 weeks, Elecat Group every 2 months. The most recent releases landed on October 9, 2026 and October 24, 2026 respectively.
