Written reviews complicate that: 0% of Lennox Smart Tech's written reviews are positive against 67% of iFLO PRO's, so the app with the better star average is not the one people write more warmly about.
Lennox Smart Tech ships an update every 2 months, iFLO PRO every 4 months. The most recent releases landed on August 15, 2026 and September 18, 2026 respectively.
