Foodist is my nutrition management program. I originally wrote it for Windows Mobile, but I've since transformed it into several apps for Apple devices:
  • An iPad app
  • An iPhone/iPod app
  • A Mac OS/X program
Foodist for Mac OS/X is not currently for sale and I'm no longer making the Windows Mobile version available.

How to Use Foodist for iPad

Foodist for iPad consists of one main screen. I designed it to be quite simple to use. You should be able to jump into it and rapid-fire enter your foods and get out of it. There's no tedious searching through 10000 foods. I carefully chose the approximate 570 foods that are offered so remove redundancies and emphasize foods that a health-oriented person eats. There are a few "junk" foods but not many.

I deliberately designed Foodist to minimize the number of steps required to enter foods, and to make it a quick operation. I had to have it this way: I've been using the program daily for over a year.

Here are the steps:

  1. Take out your iPad and unlock it.
  2. You choose Foodist from the menu.
  3. Foodist shows the main screen that provides all the functionality that you need to record and review your intake.
  4. Using your finger, tap a food category.
  5. Select a food from the list of foods in the category. Choose the closest food item to whatever you ate. It is not important to be super-exact.
  6. Select a quantity. This will cause Foodist to add that quantity of the selected food to your daily list of foods consumed. The nutritional summary in the lower right part of the screen will update your nutrient totals for the day.
  7. Press the power button and set the iPad aside.

At present Foodist's master list of foods contains over 500 common foods. These are predominantly healthy foods but I have added some fast foods, snacks and unhealthy foods (like butter and hamburger) on request, as most people eat these from time to time.

The Foodist for iPad User Interface

Click to enlarge:

As you can see from the screenshot, there are numerous buttons with words and numbers in them. These permit you to operate the program without messing with drop-down menus or switching between screens.

In the lower-right is the nutritional summary, which tells you how many calories you've consumed on the current day and what the nutrient tallies are.

  • If you want to see a 7-day average, press Mode.
  • If you want to see a 30-day average, press Mode again.
  • If you want to see a month-so-far average, press Mode again.
  • If you want to return to Daily Totals mode, press Mode a fourth time.

In the current version of Foodist, the top-left cluster of buttons are food categories:

  • Grains
  • Veggies
  • Fruits
  • Meat and beans
  • Dairy i.e. milk and eggs
  • Cereals
  • Nuts e.g. soy
  • Oils
  • Sweets and Fast Foods
  • Beverages
  • Soups
  • Recent Foods = list of foods recently consumed

The top-right cluster are food quantities. If you eat an amount that is not there, simply combine smaller amounts e.g. for 1.5 apples enter 1 apple and then ½ apple.

The lower button set also includes buttons for deleting an item (Delete) and going to previous day ← or next day "→".

Lastly there the Ranges button, which changes what is shown in the results area:

  • Ranges = switch the displaying the total percentage of kilocalories consumed for each nutrient. When pressed the button changes to say "Summary".
  • Summary = switch back to the summary of amounts of each nutrient.

In order to set your kilocalorie goal, go into the iPad Settings feature on the main iPad screen. You can set it there.

In order to change between English measurements and Metric, likewise go into Settings.

The Help button provides a brief overview of how to use Foodist.

The Email button (a picture of an envelope) provides you with the ability to email the nutritional results text.

Hand-entered foods

I hand-entered a small subset of the 7500+ foods, and these lack the full nutrient data that the USDA provided for its foods. I simply copied the Nutrient Facts from the back of the packaging for the Other category foods.

How to Use Foodist for iPhone and iPod


Foodist for iPhone and iPod is a separate program from Foodist for iPad. (They are not a combined or "universal" app.) It provides most of the same underlying functionality (but not all) and the same foods as the iPad version, but the user interface is significantly different due to the much smaller screen.

Foodist for iPhone and iPod is also a navigation-based app, meaning that when you press buttons, frequently this causes a new screen to slide into place.

The iPhone/iPod Foodist now does support the Search by keyword feature from the Add Foods screen.
