Verdict
The clearest difference is update cadence: CPU at fortnightly against DevInfo X's every 2 months. CPU also leads on ratings volume (116 vs 16). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. CPU sells 1 one-off in-app purchase and DevInfo X sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for CPU against 4.6 for DevInfo X. That said, the two scores are not equally well evidenced: CPU has 116 ratings behind it against 16, so its average is the more settled of the two.
CPU ships an update fortnightly, DevInfo X every 2 months. The most recent releases landed on November 7, 2026 and October 31, 2026 respectively.
