The official companion application for openHAB - an open source home automation system. The open Home Automation Bus (openHAB) project aims at providing a universal integration platform for connecting home automation technologies into a single intelligent system. With more than 3000 things that openHAB can connect to, there’s virtually nothing that can’t be integrated. Its advanced rules based architecture allows complete automation using several popular scripting languages (Java Script, Ruby, Python, Java, RDSL, and more ) as well as visual rule designers using either drag and drop interfaces or simple “If / Then” forms. The new openHAB UI allows users to easily build beautiful interfaces customized to their needs. openHAB is designed to be absolutely vendor-neutral as well as hardware/protocol-agnostic. Key Features: * Integrates seamlessly with your own openHAB UI (Main UI or sitemaps) * Control everything on your openHAB server directly or remotely through the free openHAB Cloud service (https://myopenhab.org) * Enhanced push notifications with media from openHAB Cloud and the openHAB cloud binding * Apple Watch companion app * Natively supports both iPhone and iPad Make openHAB the central integration and control point of your Smart Home.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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 27, 2026 and October 23, 2026 respectively.
