So you’ve overcooked a fancy grass-fed steak. You’ve heard that by cooking food sous vide — that is, inside a plastic bag submerged in a precisely regulated water bath — your beef, fish, pork, or what have you comes out at the ideal temperature each and every time, without fail.
But which circulator to choose? Currently, the two kings of sous vide cookery are Anova’s Precision Cooker and Breville’s Joule. Read on to explore how these devices stack up across four key categories: design, apps, performance, and setup.

Overall Design
The principal design difference between these two machines is that the Anova features a built-in display and controls, while the Joule — which users operate entirely through a companion app — brandishes a single button. Without onboard controls and the innards that come with them, the Joule is considerably lighter and smaller than the Anova device.
Another major difference lies in the way these two circulators attach to pots and other cooking vessels. The Anova utilizes a height-adjustable clamp (basically a swanky vise), while the Joule offers three options for securing the device: a standard clip that fits most thin-walled pots, a larger clamp for coolers and the like and a strong magnetic base that makes setup ridiculously straightforward, provided you’re using a pot made of metal.
