# ThermoLinx vs Flo by Moen™

The clearest difference is rating: Flo by Moen™ at 4.0 against ThermoLinx's 1.7. Flo by Moen™ also leads on ratings volume (1.9K vs 7). ThermoLinx's advantage is review sentiment (44% vs 35%) and iOS requirement (10.3 vs 15.0). 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.

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.
