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

√ Full international support

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.

√ Add exercise to receive additional calories.

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!

Pretty good, easy to use, but doesn’t give full nutritional profile

This app is easy to use, has every food imaginable, but it’s goal is wieght loss/gain and so it only tracks calories, carbs, protein, fats, fiber and sodium.
I was looking for an app that would track FULL nutritional values, like vitamins, minerals, etc. So for me this is not going to work.

Decent Software for Tracking what you eat

There’s not a lot out there (for Mac) for tracking what you need, calories and monitor nutrition. This seems to be the overall best of the offerings. The information provided does help guide you in making better choices in what you eat. The food data base is robust and there was nothing, so far, I wasn’t able to find and log. It kind of reminds me of a banking account. You get so many calories to consume each day. When you run out (no more calories available) you run out; sort of like running out of money in you banking account. Perfect Diet Tracker is as accurate as you are putting in all of the foods you eat, in the correct amounts. I also like how you can log your exercise as well. If you are physically active this effects the number of calories and adjustments are made after you’ve recorded your activities I was looking forward to the . I’m a bit disappointed that I am not able to find the accompanying app for your mobile device so I wasn’t able to synch, via dropbox, as well. This is one of the reasons I bought this. I contacted the developer (submitted a service ticket) but got no response. Support seems to be sorely lacking. So if you can “wing it” yourself Perfect Diet Tracker may be for you. It’s not perfect though.

Comprehensive and intuitive

I have used a number of simlar applications over many years including back in my dark Windows days and I have found Perfect Diet Tracker to be very intuitive to use and very comprehensive for individual use. I think that it strikes a very good balance between ease of use and a rich set of features. I’ve been using it for over a year now and I’m completely satisfied with it.
