Food Diary is an iPhone app that lets you keep a journal of the things you eat throughout the day. It keeps track of 90 days’ worth of food entries and charts your calorie consumption per day. It also has a BMI (body mass index) calculator, and a total caloric intake calculator for setting the target number of calories to eat each day to maintain or to lose weight, based on your gender, height, weight, and age.

The main view shows entries
from the past 24 hours.

The history list view shows entries
for each of the past 90 days.

Frequently Asked Questions

Q: Can I save my own presets?

A: Yes. Create a new entry, and then click on the Presets button, go into the Custom presets list, and click on the "Create New Preset" button to add your own preset.

Q: How do I get Food Diary to start a new day? The first screen only lets me add to yesterday’s total.

A: The first screen shows the past 24 hours, so it’ll always show part of yesterday that’s within the past 24 hours. So if you have breakfast at exactly 6:00 AM every day, when you launch Food Diary before 6 to enter your breakfast, you’ll see yesterday’s breakfast. But if you launch it again at 7:00 AM, yesterday’s breakfast will no longer be shown, only today’s. There isn’t a way to change that, but you can use the History screen to look at just today’s entries.

I designed it this way because some days I don’t eat meals at set times, and sometimes the mealtimes aren’t easily categorized into “breakfast, lunch, and dinner.” So by showing a rolling window of the past 24 hours, I can see whether I’m within by calorie budget without thinking about what time it is or what this meal is called.
