Ratio Smart Phone App: Video Demo

Published: Mar 10, 2010 · Modified: Mar 10, 2010 by Michael Ruhlman · 59 Comments

At last, we've put together this basic video demonstration of Ratio: The Smart Phone Application (built by Will Turnage, designed by Leah McCombe) so that people can see what it does and how it works. I love the application because it's truly useful.  If I'm making hamburgers or meatloaf, it will give me the amount of seasoning I need depending on how much meat I have.  If I only want a few cookies, not two dozen, it will create the recipe for me.  If I find I only have one egg, but still want to make a blueberry muffin, it calculates the amount based on one egg.  If I want to whip up a last minute caramel sauce it tells me how.  If I want to know even the basic proportions of a stock, it's there for me.  It's also a great ounces-to-grams converter.

This application will be of special value to anyone who works in a kitchen and to any and all culinary students.  And you chefs, authors, and bloggers who develop your own recipes, this application provides the trunk from which a thousand variations branch off.   I hope you'll have a look!

This is version 1.0.1, with all bugs taken care of.  Will and Leah are working on the Droid version now!

Here are some comments and reviews about the application:

Russ Parsons, in the LATimes Blog: "Michael Ruhlman wrote a really good book earlier this year called Ratio. Now he's gone out and turned it into an even better iPhone application. ... And though [his] approach may seem a little mechanistic in a cookbook (what if you happen to want a cookie with a different texture than the one chosen?), it's sheer genius in an app, where the expectations are different. Think of 'Ratio, the App' as a combination culinary pocket calculator and aide-memoir."

Chicagoist: "This application is so good it almost makes us regret buying the book first. ... At $4.99, it's a steal."

From the Village Voice Blog: "While Ruhlman's app enters an already crowded market for cooking-related iPhone applications, with its gee-whiz calculations, it has the potential to be one of the most useful. The home cooking world may finally have its own version of Turing Bombe, complete with pretty colors and custard icons."

    Would be rediculously excited if there was a version for my windows mobile device... almost tempted to buy an iTouch so I could get this... but I suppose that's a little over the top.

    I'll buy the Android version when it comes out just to support the blog. Thanks, Michael.

    If I do that, can you give me back full articles in the RSS feed? 🙁

    I have a review of the Ratio app coming up in the next week or so. I want MORE! More international foods; more ratios, sourdough, for instance; more customization; just MORE! I do love this app and it's one of the few I use in the kitchen, leading me to wonder if it's time I sous vide my iPhone.

    I'm still a Luddite when it comes to mobile devices, but this is definitely a cool app. I love the book because it makes scaling down for 1-2 people very easy. My high-tech purchase was a digital kitchen scale so I could use the ratios (and also to try out some of the recipes in Under Pressure).

    A note about the reviews: it seems that Russ Parsons didn't actually read Ratios, or he would have realized that there were several cookie ratios depending on the texture/style you're going for.

    I'm another who doesn't usually pay for apps but I'll definitely buy the android version when it comes out. I love ratios, my wife wanted chocolate souffle the other night and thanks to Ratio I knew exactly what to do with the leftover egg yolks, we had a nice vanilla custard sauce to pour over the souffles

    New Feature Request: Boy would I love a simple guide to the recommended internal temperatures of meat, fish, poultry. Would be a great little "cheat sheet" addition to the app. Not sure it fits within the "Ratio" app, but a little "cheat sheet" section would be wonderful.

    Excellent demo. I work in the software industry (in marketing) and we do demos all the time. A good one is clear, succinct and leads to a compelling event. So I'm sure your sales will increase as a result. I have purchased Ratio and must say it is one of the best apps on my iPhone. What a great tool. Thanks!

      The app doesn't work on the iTouch (at least not when I tried to install it a couple months ago). You'll get a message saying it only runs on the iPhone software.

    Michael - GREAT demo video. Simple, clear, to the point! You sell the benefits via your person use of the app rather than just the features. Successful direct response selling 101. Happiness, efficiency, family and all in your kitchen. Wonderful. Best of luck with many more app sales. All you need now is the "envy" related to not having the app. Cheers - Bill

    Michael would it be too much to ask for you to port that cellphone application to a simple Excel worksheet...??? Not that this crowd..is into Excel... but I don't have a high power cell phone right now...
    I ask because maybe... you can push a switch or something and make it happen...and hey if I am interested in that... maybe others are..Too!

    I bought the app a couple of months back, and I love it maybe more than the book... because it is always with me. My friends and family are always shocked when I know how to do something fancy when I am at their houses (they just think I'm playing with the phone, Bwah-hah-ha), and for that reason alone it was worth it.

    Ruhls,

    This is absolutely astounding.

    I do not have an iphone and if I did, I would not have time to answer it.

    However,

    I am reading "The Reach of a Chef" right now (in fact, devouring it) and what you have done here has exceeded everything I think the Food Network and Vegas set out to do.

    I think the Food Network, unless re-thought, will be regarded in history the same way CNBC is for Stock advice. That, would be bad.

    Vegas - it is what it is.

    This, my friend, is one for the history books.

    You actually have come up with something useful that ALL cooks can use. and with great results.

    Congratulations!!!!!!

    I am so proud of you!!!!!!!!!!!!!!!!!!!

    Hello Michael

    I haven't wanted and searched for something like this for a long time. Was eager to get started with it and just finished the download to my ipod touch. I think I will buy the book as well. It will be so helpful in the development of recipes. It will be especially helpful when trying to recreate my mother's recipes, especially when she says add as much flour as you think the amount of eggs you use will take. I have hopes to get all her recipes in recipe form so that we can create a family cookbook for all to share.

    Thank you!!

In fact Michael you could do the cd with the new book thing. You know, include a cd of this application with your new edition of tha book "RATIO".
    That would give me an excuse to give my book away and buy the new book/CD combo.
