# Mobile Master vs Raybench

The clearest difference is rating: Mobile Master at 4.5 against Raybench's 2.5. Mobile Master also leads on ratings volume (1.2K vs 4) and review sentiment (72% vs 53%). Raybench's advantage is ads (none vs shown) and update cadence (every 3 days vs every 6 days). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. Mobile Master sells 3 in-app purchases, starting at $0.49 per month and Raybench sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Mobile Master holds the better App Store score, 4.5 against 2.5. That said, the two scores are not equally well evidenced: Mobile Master has 1.2K ratings behind it against 4, 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 53% of Raybench's.

Mobile Master ships an update every 6 days, Raybench every 3 days. The most recent releases landed on October 8, 2026 and September 27, 2026 respectively.
