First Proof

App Store

First Proof is a tool that I wanted for my personal baking and recipe development. It facilitates volume to weight conversions (e.g. cups to grams) for many ingredients and allows you to save your own. It also allows you to store, convert, scale, and annotate recipes during the development process. More functionality coming soon.
