Adding a pinch of math

Chefmath logo

There are plenty of cooking resources in internet and most of them are worth trying. But often the ingredients are for 4 servings and you want to try the result by yourself before sharing the dish with friends. Or you are planning a party and need 20 servings. Chefmath computes the correct amount of each ingredient for you. Just select the original number of servings, the desired one, fill the list and get the result. And if you run into basic foreign measurement units, Chefmath can convert them for you.

From the shopping cart to the pot

When the math is done Chefmath can help you checking what ingredients you need to buy and be a very easy shopping list while you are at the market. You will never forget to buy ingredients: no more last-second rush for shop. With the same intuitive interface Chefmath will help you remembering to use all the ingredients you need. The very important spice for your new dish will no more stay unnoticed under the eggshells. You will notice that everything is in place at a glance. Green light for the chef.

Proof of concept

In developing this application we decided to follow an innovative approach that has to be language independent. Chefmath is an app without words. All the indications and actions are represented using symbols and icons only. The only, necessary, words of the app (i.e. the names of the ingredients) are written by you in your preferred language.

It is not easy to choose sysmbols that have the same specific meaning in different cultures. We choose symbols taken from the visual language of internet, standard user interfaces, international measurement units and street color code. We slightly differenciate active buttons from icons, we use dialogs to catch your attention and we always use a secondary code beside colors to help color blind people. We are not sure to have hit the nail on the head, thus we need your feedback! But do not worry, nothing very bad could happen to you with Chefmath: just try using it as your intuition suggests you.

In the next versions of Chefmath we will try to stress this concept even more. Stay tuned!

  1. Why do you call the app Chefmath?
    In Chefmath we use fractions, GCDs, proportions, conversions and rounding. Beside molecular gastronomy and chemical analysis we think that this is all the math you can find while cooking. Thus the name.

  2. I made a big cake for 30 servings and it was really bad. Why?
    Math is important in cooking, but it is not enough. Some ingredients, such as spices, do not scale well. Some recipes (i.e. pastry-making) have to be followed scrupulously. Chefmath is an aid, but the art is in the chef :).

  3. I disagree with your conversion ratios and/or your definition of cup/teaspoon/tablespoon, will you change them?
    If you find a real mistake in our data please let us know and we will fix it. Keep in mind that Chefmath is simply an aid and does not replace professional tools. Measurements and conversions are approximate thus suitable for domestic use only.

  4. Is Chefmath available for iPhone and iPad?
    Unfortunately the answer is no. We are aimed at Android for now but we will release Chefmath for other platforms if the request will be adequate. So keep asking!
