Verdict
The clearest difference is review sentiment: Phone Temperature Checker at 100% against CPU's 61%. Phone Temperature Checker also leads on ads (none vs shown) and rating (5.0 vs 4.7). CPU's advantage is ratings volume (116 vs 6) and device support (3 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Phone Temperature Checker holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: CPU has 116 ratings behind it against 6, so its average is the more settled of the two.
