Do I need to use the app with Cinder?

No! Cinder Grill works without the app — just set the temperature manually by turning the dial and waiting until Cinder beeps to let you know your food is ready. Use the dial for temperatures above 200 degrees F and use the Cinder Grill app for temperatures below 200 degrees F.

Cinder app provides a better set-it-and-forget process: Select the food you're cooking from a list, choose your desired doneness (e.g. rare, medium, well done), and Cinder will not only estimate how long cooking will take (P.S. Cinder is faster than sous-vide), but it'll notify you when your food has reached temperature.

That's all there is to it. We've kept the app dead simple. It gets out of your way.

The Cinder App is currently available for iPad and iPhone here, and Android here.
