I bought one of these years ago, and took a look at it. The app let's you remote control the stick and pick recipes that will autoset the temps. That's about it. The stick has buttons on it, and it's not like you can have it add the food to the water bath remotely. It'd pretty easy to knock in the temp at the heater while you're there

Sous vide is a "set and forget" cooking method like a crockpot. You can walk away and leave the thing running long past the minimum time and have no issues because the whole point is it takes food to an exact temp and no further. So even any alerting "temp reached" it may do now isn't really useful.

This feels like a "pick the carcass" attempt to make some money at all. I expect the company is probably in a bad state if this is the game they are playing.
