Lower-cost units are now available in the form of a "stick" which has a clip to attach it to the side of the cooking vessel. Sous vide sticks provide a heating element, controller, and motorized impeller. The higher-cost units provide a more precise degree of control over the water temperature. Devices are becoming more user-friendly, with apps affiliated with most of the devices, including brands such as Nomiku, Anova Culinary, and Joule. Apps guide people through the cooking process, with some units having voice-control integration and Wi-Fi interfaces to control the device remotely.
