Verdict
The clearest difference is rating: Rheem at 4.6 against CoChecker's 2.7. Rheem also leads on ratings volume (1.8K vs 3). CoChecker's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 16.0). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Rheem holds the better App Store score, 4.6 against 2.7. That said, the two scores are not equally well evidenced: Rheem has 1.8K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of CoChecker's written reviews are positive against 43% of Rheem's, so the app with the better star average is not the one people write more warmly about.
CoChecker ships an update every 3 weeks, Rheem monthly. The most recent releases landed on October 22, 2026 and October 23, 2026 respectively.
