# Mobileraker vs Polar Cloud

The clearest difference is rating: Mobileraker at 4.9 against Polar Cloud's 3.0. Mobileraker also leads on ratings volume (908 vs 2). Polar Cloud's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Mobileraker sells 10 in-app purchases, starting at $1.99 per month and Polar Cloud sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Mobileraker holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: Mobileraker has 908 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 81% of Mobileraker's written reviews are positive against 100% of Polar Cloud's, so the app with the better star average is not the one people write more warmly about.

Mobileraker ships an update every 5 weeks, Polar Cloud every 2 months. The most recent releases landed on November 7, 2026 and October 31, 2026 respectively.
