The W-BACnet app has arrived! Upgrade firmware for LumenRadio W-BACnet devices by connecting to and upgrading the LumenRadio Gateway in the network through the app. In the Network map you will find a system overview where you can see signal strength, edit names of wireless nodes as well as seeing the health of the RS485 bus including which BACnet MS/TP address that is connected to that wireless node. You can also connect to any node in the network and change their name (up to 20 characters). The W-BACnet app requires W-BACnet firmware 3.1.1 and above, which can be downloaded from the LumenRadio support webpage. Note that you need to install FW 3.1.1 or above on the gateway from the nRF connect app to enable the functionality. It is also required to have at least 3.0.0 or above on all nodes in the network. You will need to update all nodes individually if they are on version 2.2.3. This will be the last time this is required. All future updates can be done by either this app or from the nRF connect app.
KeyShelf

KeyShelf is a private inventory for every physical key you own. Photograph both sides, write down what it opens, tag it, and never stand in front of a lock guessing again. Add a key in seconds: front and back photos, a color and head-shape quick-pick for keys without photos yet, the place its lock lives, and what exactly it opens. From there the shelf does what a junk drawer never will: instant search that ignores accents and looks through names, descriptions, places, tags, and even the people holding copies. Keys get copied, and copies wander. KeyShelf tracks every copy: who has it, since when, a note, and a lent-out flag that stays on the key until the copy comes home. The People screen flips the question around and shows every holder and exactly which of your keys they carry. WHAT YOU GET - Key inventory: front and back photos for every key, in a clean shelf grid - What it opens: a plain-words description plus a structured place (home, cottage, office, mailbox, padlock, vehicle, and more) - Tags and instant smart search: accent-insensitive, across names, descriptions, places, tags, and copy holders - Copy tracking: every copy with its holder, note, hand-over date, and a lent-out flag - People: everyone who holds a copy, and which keys they have - Private Face ID lock: optional, with your device passcode as fallback - Printable key registry PDF: a clean table grouped by place, photo thumbnails optional, with copy holders and lent flags - Syncs across iPhone, iPad, and Mac with iCloud FREE AND LIFETIME Free covers a full shelf of 12 keys with photos, search, tags, copy tracking, and the Face ID lock. Lifetime is a single purchase that unlocks unlimited keys and the printable registry PDF, forever. No subscription. PRIVATE BY DESIGN No account of ours and no tracking. Your keys live on your device and in your private iCloud, which we cannot read. An optional Face ID lock keeps the shelf closed to anyone but you, and Settings has a Delete All My Data control that erases everything from your device and your iCloud. PRICING KeyShelf Pro is a one time Lifetime purchase of $12.99 USD. Payment is charged to your Apple Account at confirmation of purchase.

Verdict
The clearest difference is update cadence: KeyShelf at every 9 days against W's every 3 months. W's advantage is iOS requirement (15 vs 18.0). On price, ads, in-app purchases and device support there is nothing between them.
