# LeanMD vs A3 Smart Home

The clearest difference is review sentiment: LeanMD at 67% against A3 Smart Home's 29%. LeanMD also leads on update cadence (every 3 weeks vs every 2 months) and iOS requirement (15.1 vs 17.0). A3 Smart Home's advantage is rating (4.6 vs 4.2) and ratings volume (1.8K vs 11). 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.

A3 Smart Home holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: A3 Smart Home has 1.8K ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 67% of LeanMD's written reviews are positive against 29% of A3 Smart Home's, so the app with the better star average is not the one people write more warmly about.

LeanMD ships an update every 3 weeks, A3 Smart Home every 2 months. The most recent releases landed on October 22, 2026 and October 25, 2026 respectively.
