# Mobile Master vs CPU Info

The clearest difference is rating: Mobile Master at 4.5 against CPU Info's 2.5. Mobile Master also leads on update cadence (every 6 days vs every 3 months) and ratings volume (1.2K vs 2). CPU Info's advantage is in-app purchases (none vs 3) and ads (none vs shown). On price 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. CPU Info asks for nothing beyond the download.

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 2, so its average is the more settled of the two.
