Using Cookulus™ for iPhone/iPod Touch and iPad

If you need help with any aspect of Cookulus you will find useful tips by clicking on the information icons found in the app. The following overview may also answer your questions.


Cookulus master recipes are parametric. Built on a patent-pending algorithm, various attributes of a recipe are graphed against one another, creating a master recipe that can be morphed in multiple dimensions by sliding one or more of the adjustable sliders. When you find a recipe that you especially like you can save the recipe (iPad only) by touching the new recipe button in the toolbar. You can return to a saved recipe anytime and, if you choose, edit it, and save the new version, or delete it.

Master recipes and saved recipes (iPad only) are listed in the recipe library. When you click on the name of a recipe in the library it will activate in the recipe screen.


The Modulator is comprised of 3 tools: the Parameter Controls, the Yield Adjuster, and the Measurement Selector.

  • The Parameter Controls (composed of sliders and pull down menus) are your way to change the attributes of a recipe. Details on using the controls to modify a specific recipe are included in the information section of that recipe. Moving one slider will change a specific characteristic (the crispness or thickness of a cookie, for example), but because sliders interact with one another that characteristic is modified further by moving the other sliders. The combination can be complex, resulting in more than a thousand unique combinations for each recipe.
  • Sliding the Yield Adjuster multiplies the amount of ingredients in a recipe by a factor of 1 to 5. For example, a typical Cookulus cookie recipe makes 2 dozen (24) cookies. Setting the yield adjuster to 2X adjusts the amount of ingredients to be enough for 4 dozen (48) cookies. Sliding it to 5X yields 10 dozen (120) cookies.
  • The Measurement Selector allows you to choose the system of measurement used in the recipe. You have your choice of two weight measures (Metric and U.S.) and two volume measures (U.S. and Precise). Metric measure is stated in grams and U.S. weight measure is stated in pounds and ounces. There are 28.35 grams to an ounce. Since we round to the closest 1/4 ounce (7.1 grams) stating a measurement in grams is more precise than ounces. Similarly we round U.S. volume measure to the nearest 1/4 teaspoon or 1/4 cup. If you select Precise Measure you will get a descending series of measurements that become ever more detailed. For example: 156 grams of flour is equal to a rounded measure of 1 cup, but it is more precisely stated as 1 cup plus 1 tablespoon plus 1 1/4 teaspoons.
  • You can also choose to assign a system of measurement for an ingredient that is different from the way the other ingredients in the recipe are measured. As an example, let's say that you have chosen to use U.S. volume measure as the default system of measurement in a recipe, but you prefer to measure flour by weight. Touch the ingredient detail button (see below) and a popover window will appear with a measurement selector across the bottom of the window. You can leave "General" selected and it will continue to use whatever measurement system you choose in the Modulator panel, or select "Choose Below" to set a specific system for this particular ingredient. If you choose metric or U.S. weight measure, flour will always appear as a weight measure in the recipe, while the other ingredients remain in volume measure. You can change the system of measurement of any ingredient in this way.


Use the built-in kitchen timer to time your Cookulus recipe. As you adjust the sliders the cooking time in the recipe shifts accordingly. When you are ready to start cooking touch the clock icon next to the time in the recipe and the numbers on the timer will show the cooking time. When you touch the start button the timer will start and continue counting down to 0:00, at which point a chime will sound. To stop the chime touch the pause/stop button.

If you pause the timer before it sounds the countdown will halt; to restart the countdown touch the start buttona gain. If you would like to adjust the time on the timer manually you can do so by using the +1 and -1 buttons to add and subtract one minute, respectively.

Detail Buttons

Words within buttons are linked to information about that topic. Touch a highlighted ingredient and detailed information about purchasing, storage, and using that ingredient will appear on the screen in a popover window. Information popover windows are also provided for equipment and cooking techniques.
