Great app for on the fly cooking. Read the book to get the most from the app. I weigh the eggs in a bowl as well as the liquid, like milk or cream. When using the volumne setting, I place the eggs in a measuring cup to prepare the dish. Weighing is more accurate for large portions. Volume is easier for home cooks fixing dinner. It's a handy tool to have.

Seems to be comprehensive. But it really needs pizza dough in the app.

Highly recommend you read the book Ratio to understand how great this app is. Knowing basic ratios allows you to cook on the fly, to tweak dishes and make them your own. Example: rice. Liquid to dry rice 2:1. I’ll make a chicken &sausage jambalaya with two cups of rice. I’ll need 3.5 cups liquid plus the .5 cup liquid the onions, bells and celery will throw off. I’ll sauté up a pound each chicken and sausage, sweat the vegs and the stock, and the rice. Ka-BOOM!

This an excellent cheat sheet. Works very well.

Nice app that has the book published ratios. Very convenient

Five dollars? You could fit the information this app contains on a double sided, letter sized sheet of paper with 12 point type. I like the concept and it has its uses. But for $5 I'd like to see how these ratios adapt to different dietary requirements, or something a little more encyclopedic in its scope. For one thing, it's extremely French classical in its viewpoint. Wish I'd read the reviews prior to purchasing.

Complete waste of money. Don't bother with this app.

I have this book and I thought there'd be a little more to the app, little skimpy for the price.

Too expensive for what you get in this app. I expected more from the brand.

But overall it's too limited for the price. I used it for a couple months and then deleted it from my iphone.
