If anybody from the company is reading this, why an app? This seems like a new trend in cooking equipment and I fucking hate it. I don't want to have to flip between a half dozen apps just to make dinner. How hard is it really to put a small display and a handful of buttons on the appliance in question and make it usable without having to use my phone? Maybe I'm just strange but as much as I love the idea and really want one, the lack of a UI on the device itself is currently holding me back from ordering one. Call it the "Old Luddite retro model" and charge me $50 bucks extra if you have to, but give me an interface right on the device and I'll give you my credit card details.
There's only one version, and it has both an app and a an onboard UI based on a knob-button with an embedded dot matrix display. We're very conscious of the tradeoff between onboard and app controls.
The knob lets you have full manual control of temperature, but is not a good way to share recipes or learn how to cook something you don't do every day. So you want to make a quick panini or egg, the knob is great. On the other hand, we don't want to be like your microwave, with tons of features hidden behind scrolling text prompts and a keypad.
On the other hand, an app interface lets you have a different UI for each food type, so you can ask for a medium rare steak or light brown caramelized onions.
Once you've used the app to set things up, you'll be hands-on in the kitchen, so the next few steps can be controlled from the knob or the app.
