You still need to in to the companion app because the device needs the online backend for computing the render.

But on iOS you can log in with apple. And there is no need to pair with google calendar if you use the image url feature:

Batteries drive up the cost for certification and shipping. I think a battery works better together with a bigger, more expensive display, where these costs are less of a concern and which you cannot place on a stand.

(Even though you can definitely hang my display up on the wall and if you don’t have a socket nearby, you can plug it into a battery pack)

Sorry if that’s a lot of text but I think about this stuff every day :D

Hard decisions!
