Looking for App Beta Testers

My sous vide app is ready for testing. iOS only.

This is an app for advance sous-vide cooks who aren't looking for someone else's recipes. There are no food pictures. It's not tied to a brand of circulator.

You decide your target core temperature, tell the app the important details. It will calculate cooking time. If you wish, it will calculate surface and core pasteurization times as well.

Unlike the published tables, this app uses thermal properties and pasteurization properties researched for each specific food type.

Even PolyScience's built-in app uses the same values for everything. In real life, proteins vary in heat diffusivity by more than 30%. Pasteurization times for the same bacteria in different proteins vary by more than 500%.

Think of it as a modern replacement for the much-loved, now discontinued, Sous Vide Dash and Sous Vide Toolbox apps.

If you'd like to be a tester, send me a note at info @ under-belly.org.

I'll send you an invitation link. It will download the Test Flight app onto your phone, which installs beta releases. When the final release is ready, you won't need Test Flight anymore. 

 Here's the help / instructions page. In progress.
