Verdict
The clearest difference is rating: Lennox Smart Tech at 4.5 against Della+'s 3.6. Lennox Smart Tech also leads on update cadence (every 2 months vs every 3 months). Della+'s advantage is ratings volume (423 vs 60) and review sentiment (9% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Lennox Smart Tech holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: Della+ has 423 ratings behind it against 60, so its average is the more settled of the two. Written reviews complicate that: 9% of Della+'s written reviews are positive against 0% of Lennox Smart Tech's, so the app with the better star average is not the one people write more warmly about.
Della+ ships an update every 3 months, Lennox Smart Tech every 2 months. The most recent releases landed on September 19, 2026 and August 15, 2026 respectively.
