Is the Anova Precision Cooker 3.0 worth it over the cheaper Nano?

The 3.0 adds a touchscreen, Wi-Fi and low-water shutoff over the Nano, and its 1100 watts heat a large pot faster. If you only cook for one or two and use the app anyway, the Nano covers the basics.

Do I need the app to use it?

No. You can set temperature and time on the two-line touchscreen and start cooking without a phone. The app adds recipes, remote monitoring and notifications.

What size container do I need?

The unit is 12.8 inches tall, so use a pot or container deep enough to hold it with water above the minimum line. A 12-quart pot handles most family-size cooks.

Can it cook from frozen?

Yes. Add roughly 50 percent to the cooking time for frozen meat, and use the app's guide for specific cuts. The low-water sensors protect the heater during longer cooks.

What comes in the box?

The cooker, a detachable clamp and a container are included. You supply the water and the pot or container you clamp it to.

How is it different from the Precision Cooker Pro?

The Pro has a higher flow rate for faster water circulation, a longer warranty and more cooking modes. The 3.0 matches it on wattage and accuracy for everyday cooks.
