# Mobileraker vs Spool

The clearest difference is ads: Spool at none against Mobileraker's shown. Spool also leads on review sentiment (100% vs 81%) and update cadence (every 2 weeks vs every 5 weeks). Mobileraker's advantage is ratings volume (904 vs 5) and iOS requirement (15.6 vs 26.1). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mobileraker sells 10 in-app purchases, starting at $1.99 per month and Spool sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for Mobileraker against 5.0 for Spool. That said, the two scores are not equally well evidenced: Mobileraker has 904 ratings behind it against 5, so its average is the more settled of the two. Written reviews are what separate them: 81% of Mobileraker's written reviews are positive against 100% of Spool's.

Mobileraker ships an update every 5 weeks, Spool every 2 weeks. The most recent releases landed on October 18, 2026 and October 10, 2026 respectively.
