Thank you Jeff!

Awesome app and love the chef! So excited to be among the first to use it! I loved his online calculator which saved my life and made dosing super easy! I love what they did here but it needs some work on interface and what everything does.

The button image for the per serving is a bit confusing. It looks like a piece of bread lol
