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.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Lennox Smart Tech holds the better App Store score, 4.5 against 3.6.

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.
