5***** Macworld Editors Choice.

√ Create a personal diet plan

You can let the diet tracker suggest a personal diet plan based on your current situation and the targets you want to achieve or enter your own custom diet plan. The app puts you in control.

√ Track what you eat with the food diary

Track your diet adding items you eat or drink to the food diary. With over 100,000 products in the food database adding items using the smart search is quick and easy.

If you cannot find a product with the smart search you can quickly add it using a form specifically designed for the product labelling in your location.

√ Let your Mac do the hard work

The app takes care of the calorie counting and exercise tracking for you, monitoring your calorific and nutritional intake. Stay within the targets and you will achieve the weight loss you want.

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

√ Multiple users?

No problem and no extra charge. Each user can set a password so other users cannot see what you are eating or currently weigh.

You can use the right click menu to copy items and meals between users so entering meals you have taken together is even faster.

√ 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!

NO LONGER FUNCTIONS!!! 1 star should be zero.

Application wants to upgrade database files for new version but fails to do so. Let it run for over a day.
Ended at moving support files. Clearly this is broken. If it can manage to update its own support files it
means this app was not well QA’ed before release.

Helped Me Lose 24 pounds

Sticking to a diet can be difficult. Using computer software to establish goals, record progress, evaluate the relationship between the amount and type of food consumed and its affects on your weight and how you feel is very helpful. I found Perfect Diet Tracker software to be a tool I was willing to use on a daily basis. The software uses a “favorites” food list to quickly and easily record the food you eat on a regular basis. It also provides online access to a large database of foods. PDT’s privacy policy is exceptionally good, and the PDT software resides on my computer, thus my personal data is not sent over the Internet. I also appreciate how this software accomplishes the tasks of goal setting, recording the nutritional content of the food consumed, graphing the progress in weight-loss, and calories consumed, and the automatic correlation to BMI. I would like to see some improvement or better instruction on the use of goal setting once a weight-milestone has been reached, especially when you achieve your goal weight and want to maintain that weight. I have used the PDT software for a couple of years. I appreciate that I haven’t gotten nagged to pay for upgrades to the latest version. I find the software straight-forward, it provides the tracking tool one needs to keep to whatever diet you choose (Paleo, Atkins, South Beach, etc.). I found that if I don’t use PDT to monitor my weight, excercise, and diet, I gradually gain the weight back. This insight told me how valuable it is to use a software tracking tool.
