Abandoned Product
The app is currently useless, since you can’t perform the first step in the process: updating the firmware. It looks like they declared an early “end of life” on the Wio Link; I was unable to find any information on this product more recent than 2019.
Terrible
Just don’t even waste your time
Garbage
They haven't updated the app in a year. Google login crashes the app. FB login fails. You can register for an account, but when you try to log in, the connection fails. I would give 0 stars if I could.
Lame!
Won’t connect to iPhone. Waste of money
Server errors
What's the whole point of this when you can't even connect it to the app. Good concept but poor execution. I am returning the product. No customer support.
