# AX vs Mobile Master

The clearest difference is rating: Mobile Master at 4.5 against AX's 3.2. Mobile Master also leads on update cadence (every 6 days vs every 7 months) and ratings volume (1.2K vs 17). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. AX sells 3 one-off in-app purchases and Mobile Master sells 3 in-app purchases, starting at $0.49 per month. Whichever you choose, the download price is not the number that matters.

Mobile Master holds the better App Store score, 4.5 against 3.2. That said, the two scores are not equally well evidenced: Mobile Master has 1.2K ratings behind it against 17, so its average is the more settled of the two. Written reviews point the same way: 55% of AX's written reviews are positive against 72% of Mobile Master's.

AX ships an update every 7 months, Mobile Master every 6 days. The most recent releases landed on August 25, 2026 and September 24, 2026 respectively.
