Verdict

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Flo by Moen™ holds the better App Store score, 4.0 against 1.7. That said, the two scores are not equally well evidenced: Flo by Moen™ has 1.9K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 44% of ThermoLinx's written reviews are positive against 35% of Flo by Moen™'s, so the app with the better star average is not the one people write more warmly about.
ThermoLinx ships an update every 6 weeks, Flo by Moen™ every 2 months. Both last shipped on October 24, 2026.
