Get access to the best sous vide recipes and control Joule, the world’s smallest, most powerful sous vide tool, with the Joule App. From raw to ready, the app coaches you through the whole process, so cooking sous vide is simple. Just pick what you want to cook, and we’ll walk you through the rest.

The Joule App includes groundbreaking features like Visual Doneness, precise temperature control from anywhere, and a robust collection of recipes and cooking guides created by the ChefSteps team. Joule and its app were built and designed from scratch to work together, and we’re just as dedicated to the quality of our products as we are to the food we make with them. You can read more about Joule and the Joule App in publications like CNET, Wired, Lifehacker, Food & Wine, and Network World.

You tell us what you’re cooking, we tell you when it’s ready. Making a two-inch steak? Great. Just tap the Start button, and Joule will set a timer for perfect doneness. Get notified when your steak is ready—and we’ll also tell you how much longer it can stay in the water without overcooking.


• Exclusive access to our cooking guides: The app comes with step-by-step guides for everything from perfect fried chicken, to succulent salmon, to the best steak you’ve ever had in your life, helping you unlock the power of sous vide. What’s even better? We’ll keep adding new guides (and updating old ones) all the time.

• Visual Doneness: Choose exactly how you want your food to look when it’s done, then press go, and Joule does the rest. No more filtering through online forums to get the information you need. Visual Doneness takes the guesswork out of sous vide.

• Step-by-step instructions, so you can learn as you go: Every cooking guide comes loaded with quick videos that’ll teach you new techniques and help you get the best results.

• Notifications that let you know when your water is hot and your food is done, no matter where you are. Not ready to eat? We’ll tell you how much longer your food can stay in without overcooking.

• Bluetooth and Wifi control, so you can cook from anywhere.

Chefs have been cooking sous vide for decades to get perfect proteins and amazing new textures. But, it’s not fancy or complicated—Joule heats water to a very specific temperature, so you can cook food gently, with super-human precision. The water never gets hotter than you want the food to be, so it won’t overcook.

Absolutely! You can still use our sous vide guides and Visual Doneness in the Joule App to figure out your favorite times and temperatures, then manually set your other tool and make amazing meals at home.

What’s New

Version 2.73.9

We've removed some code that was no longer needed. Then we fixed a couple of bugs that subsequently scurried out. These were very mean bugs that made a lot of people blue, and if that was you, we hope this update comes to your rescue and returns things to normal PDQ.

Additionally, the Troubleshooting view, an essential part of the crew, wanted to join the party so it had a few bugs expunged, too.

Happy cooking, Joule friends!

Good, with great potential.

I have been having a lot of fun with my Joule sous vide! The machine is very easy to use, and very efficient. The app has a really great design, and has amazingly good potential - but is extremely buggy. I would love the notifications functions to work, but the app crashes every time I agree to receive notifications. Being that timing is crucial to using this machine, and the app being central to using this device, having a only partially functioning app with key features not working is a large handicap to the function of this device. If the app worked well, this easily would be a five star review for both the app and the device. I am hoping to be able to revise my review to reflect that when the app receives updates.

Love this machine!

I’m not really sure why so many people have not given this the joule a better rating. I am a Chef in the food industry and I love my joule...or joules! I have 3 of them now and looking at a 4th one. I have tried competitors, but always go back to the joule. I also have had a couple of my kitchen staff buy ones for themselves. They are precise, work awesome and have not had any issues I can’t fix with the simple troubleshooting techniques. I use the recipes as well as the manual cooking option. The updates, I feel, have been great, and the chefsteps crew seems to be continuously trying to improve the whole experience. I love the tech side of the joule(though a manual control, or even better, a control from the cloud on a desktop would be nice), and multiple users being able to control the same joule at once, is awesome!
The only reason I don’t give this a 5 star, is because I want and NEED a way to add and save my own “recipes”/cooking data. I cook some of the same things over and over, and I have tweaked the app recipes to what works for me. If chefsteps could have a section that saves personal recipes in the app so that I could quickly go back to them, that would make this machine perfect!
Thanks for the awesome joule and keep it up!

Unnecessarily dumbed down

Not only is the ersatz ‘chipper’ tone annoying, it gets in the way of efficiently using the device. It would be nice if there were a toggle to turn off the cute.

More crucially, there still isn’t implementation of basic functionality that was teased a year ago, eg using the top button to start again the same temp as last used. And obvious capabilities such as a workable log (which would have to allow you to assign titles to your cooks) or a more full featured custom cook creation option would at least partly justify the necessity of using a smart device to operate the sous vide. I have created my own time and temp profiles for everything I cook ... which I have to log separately and track changes for... and share with the 4 other families I have bought sous vide for (not all joules, because my in laws can’t handle a device without built-in controls). You would think the social sharing potential alone would motivate these wannabe hipsters to build in the ability to set custom cooks... but instead they pour development energy into another cutesy notification that makes me never want to tap on the app ever again.
Enough with the style over substance.
