# UD Mobile vs openHAB

The clearest difference is rating: openHAB at 5.0 against UD Mobile's 4.1. UD Mobile's advantage is review sentiment (50% vs 33%) and update cadence (weekly vs every 3 weeks). 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.

openHAB holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: UD Mobile has 37 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 50% of UD Mobile's written reviews are positive against 33% of openHAB's, so the app with the better star average is not the one people write more warmly about.

UD Mobile ships an update weekly, openHAB every 3 weeks. The most recent releases landed on October 29, 2026 and October 23, 2026 respectively.
