√ Let your Mac do the hard work

Carbohydrates, protein, fat, sodium and sugar intake can also monitored automatically so you can check you are maintaining a healthy and balanced diet.

The app can work in pounds, kilos or stones and accepts user measurements in feet and inches or meters. When adding products you can work with standard serving sizes, grams, ounces, kilos and more. Would you prefer to work with calories or kiloJoules? You decide.

The international food database contains products for countries throughout the world including US, Canada, UK, Europe, Australasia and more. Our database is reviewed by humans to maintain the highest possible degree of accuracy and quality and avoid duplicates.

The app includes an extensive list of exercises you can add to the diary to receive calorie credits.

√ Work with recipes and groups

The recipe and group feature lets you group ingredients and enter them into your diary, perfect for adding your own home cooked meals.

Insert a whole recipe into your diet or just a fraction (e.g. 1/2 a pie) and the app will calculate the calories for you.

√ Smart search

The smart search can use its own internal database or search the internet for additional products. The smart search learns as you use it so the more you use the app the quicker it gets, bringing products you have used before to the top of search results and correcting spelling mistakes to help you find what you are really looking for.

√ Reporting and Graphs

You can monitor your progress with the included reports and graphs. If you need to take a report with you, just print it off!

ⓘ Will the diet work for me?

The calculations used by this app work for the vast majority of people. If you are an extreme athlete, or have a very high body mass index ('morbidly obese, category III') the app can still track your diet however it will be unable to suggest a daily calorific allowance. If you fall into either group you should consult your doctor to discuss a suitable calorific allowance and nutritional profile and enter these manually.

ⓘ Product Support

We believe the Perfect Diet Tracker is quite simply the best app of its kind available and want to keep it that way!

Could be so much better!

I've used computer diet programs in the past on a PC, in particular DietPower 4.0. While Diet Tracker doesn't hold a candle to DietPower (which currently has no Apple compatibility), Perfect Diet Tracker is about the best program I've found for a Mac. What it won't do surprises me though. The serving sizes can be difficult to navigate. It's tough to add recipes and there is no progress tracking graph for nutrients. It would provide great positive reinforcement if I could simply click on the pie chart to find out how well I've eaten over the past week or month. A calorie bank would be nice, to help spot trends toward overeating over time instead of just day to day. It would be great to see the big overall progress picture instead of just the daily entries. And as big as the food dictionary is, it isn't big enough and seems to be regional, as my area of the country doesn't carry most of the brands listed. I enter a lot of food items by hand. Sometimes my Notes disappear for no earthly reason, and when the cursor or mouse pointer is in the Notes window, you get an unhelpful help bar across the box that blocks the note. But if you have a Mac and you're looking for a good basic program to track your calories, this one isn't bad. After all, the real work isn't in the data entry, it's in the effort of actual weigh loss, but any reinforcement I can get from the computer aids my goals. I wish this program had just a little more oomph.

A Good App but...

I spent pretty much all of today looking for diet app and none seem to be a user friendly or complete as Perfect Diet Tracker.

I don't know why it got such bad review 7 - 8 years ago but it is the best I have found in 2019. I just wish it had an iPad app so I coul track on that as well as my desk bound Mac.

It is simple and sort of boring, not very interactive and nothing to make it fun (medals, reminders, weekly workout plan) like others I have used. I wish weight would also be on the graph for nutritional intake/calories so I could see if what I ate and calories eaten make a difference rather than having to flip back and forth between the graphs. It has you rate your activity level whereas other apps calculate your daily recommended calorie intake based on what activities you actually enter. For this app, it does not explain what moderately active actually is. On another app, I actually lost more weight when I ate more because I had underrated my activity level so it told me to eat less. I actually needed to eat more as my body stopped losing weight because I was not eating enough. I only figured that out when the app itself updated the calculations from self-rate to what exercise I actually did. It would also be great to have the RDAs actually near the daily columns to see if one went over or under what is recommended for carbs, protein, sodium, fiber, etc.. It would also be nice to see not only current weight compared to goal weight but saying how much you have lost overall from original weight. I know it is on the graph but it is nice to see a big number as well on the summary page. But, I do like it and find it useful. I have lost 5 lbs so far in 3 weeks so it is working for me.
