Verdict
The clearest difference is monetization model: Bluetooth DMM at free against Thermal P2's paid. Bluetooth DMM also leads on rating (2.5 vs 2.0) and iOS requirement (9.0 vs 11.0). Thermal P2's advantage is ratings volume (29 vs 4) and review sentiment (11% vs 0%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Bluetooth DMM holds the better App Store score, 2.5 against 2.0. That said, the two scores are not equally well evidenced: Thermal P2 has 29 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 0% of Bluetooth DMM's written reviews are positive against 11% of Thermal P2's, so the app with the better star average is not the one people write more warmly about.
Bluetooth DMM ships an update every 2 weeks, Thermal P2 fortnightly. The most recent releases landed on October 12, 2026 and October 24, 2026 respectively.
