VM208

The DIN rail WLAN Relay Card (VM208) by Velleman for Makers combines the strength of four robust relays that you can control by installing and using this app. In other words: this you will be able to remotely control any appliance in your electrical cabinet from anywhere in the world*! For your convenience, we also added both wired (RJ45 socket) and wireless connections (SMA plug) to the relay card. There is one digital input that lets you monitor the state of any device and there are two additional transistor outputs that allow you to control 6 devices in total. In case you need even more outputs, an additional module (VM208EX) can add another 8 relays. To top things off, we designed a compact DIN rail case that perfectly fits this versatile relay card. Once you’ve installed your relay card and connected it to your preferred appliance(s), you can install the app and scan your network to connect your app to your relay card. Tip: multiple relay cards, even the DIN-RAIL Extension Relay Card (VM208EX), can be connected to your app. To make a successful connection, you will simply need to select your relay card on the list and enter your credentials. After that, you will get an overview of all your relays or channels and you will be able to give them individual names. Each channel can now be controlled: you can turn it on or off, install a timer or pulse, schedule, and even send out an email notifications at specific events.

Verdict
The clearest difference is iOS requirement: VM208 at 8.0 against nRF Connect for Mobile's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Bugs and requests
nRF Connect for Mobile
Reported bugs
4 issues- Can't read data from Bluetooth device
- Tries to ask for Bluetooth connection when Bluetooth is off. Asks to connect to devices when Bluetooth is off. Who knows what this app is doing in the background without permission?! What ever it is , it ain't good
- Tapping "tabs" doesn't work (nothing changes in the UI). To get some response from tapping UI controls typically requires (a) launching nRF Connect, (b) switching to another app, (c) switching back to nRF Connect. I've tried uninstalling and re-downloading. Same result. This used to be the bee's knees of BLE tools but it's only worth 1 star at the moment (v2.7.11).
- Cant go past the initial announcement. The app is unresponsive to the taps.
