# Mobile Master vs Test Pro

The clearest difference is review sentiment: Mobile Master at 72% against Test Pro's 13%. Mobile Master also leads on rating (4.5 vs 3.6) and monetization model (free with in-app purchases vs subscription). Test Pro's advantage is ads (none vs shown) and iOS requirement (10.0 vs 17.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Mobile Master sells 3 in-app purchases, starting at $0.49 per month and Test Pro sells 6 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Mobile Master holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Mobile Master has 1.2K ratings behind it against 70, so its average is the more settled of the two. Written reviews point the same way: 72% of Mobile Master's written reviews are positive against 13% of Test Pro's.

Mobile Master ships an update every 6 days, Test Pro every 4 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
