Totally unclear why I'd take a recipe I already have, and go to this app to convert it...to what, exactly?

Also, phones and kitchens do not mix well. You are fighting a battle trying to get people to adopt electronic devices in an environment full of water, heat, food, etc.

Question. Are you referring to converting a hardcopy of a recipe you already have?

Personally, I like taking a snapshot(s) of a recipe from cookbooks I own. That way I can bring my phone into the kitchen and leave the recipe book out of the splash zone.

I'm pretty sure people these days frequent their phone to obtain/cook with a recipe they got from the internet. Not everyone does, but I'd wager it's pretty common.
