Only thing it could realistically do is keep an already hot drink hot - which by itself isn't bad if it didn't advertise itself as being able to make a not hot drink become hot.
It is designed and advertised to keep a hot drink hot, which as you say, it does well!
They don't advertise it as a heater, and explicitly say that it won't work.

Maybe they could be more clear to avoid misunderstanding. But it works great it keeping a cup of coffee warm, and I've never even installed the app.
