Whatever your reason: a winter vacation in Thailand at the beach, a wedding, or (best of all) general fitness, losing a little (or a lot) of weight is generally a great thing if done in the proper way through exercise and correct eating. Obesity is one of the major health risks of our time, and the Jamie Olivers of the tech world have cooked up thousands of websites and apps that may help you count calories and fight the flab. Let’s take a look at 8 of the most popular (in no particular order):

MyFitnessPal (Free)

  • Android – Rating: 4.7 stars (from 209,892 reviews)
  • iOS – Rating: 4.5 stars (from 279,730 all-time reviews)

One of the best reviewed weight loss apps on Google Play, and an editor’s pick from both PC Mag and Wired, MyFitnessPal has a pretty impressive food database of over 2 million foods that it can count calories for.

Diet Assistant is similar to Diet Point, but seems to have a few more technological features such as customizable alerts, a home screen widget and database backup and restore.

My Diet Coach takes a little different approach from the apps above, focusing solely on women and offering a bit more in the way of motivational prompts than hard data.

Fooducate (Free)

  • Android – Rating: 4.4 stars (from 2,653 reviews)
  • iOS – Rating: 4.5 stars (from 6,390 all-time reviews)

Like MyFitnessPal, Fooducate allows you to scan a UPC barcode to learn about that food’s nutrition facts before purchasing. However, while MyFitnessPal has a range of features, Fooducate focuses on giving an easy-to-understand overview of each of the 200,000+ foods you can scan into the app, giving the good – and the bad – of each food.
