What Is The Best Free Keto Diet App

Following the keto diet has the potential to deliver you amazing results, but getting there isn't necessarily easy. The key to getting into a state of ketosis is eating way less carbs and instead more fat, so that your body can begin to use it as source of energy, allowing you to gradually lose weight.

But sticking to the keto diet requires you to keep tabs on your macros and what you're eating. And unless you've got a photographic memory, you may need to call in some assistance. Don't worry though, there's an app for that—actually a bunch of them.

When considering an app to help you with your keto diet, Alix Turoff, RD, recommends choosing one that can help you keep track of your carbs. "Any app can really work for tracking your food when on a ketogenic diet, but for some, the ability to track net carbohydrates (without having to do the math manually) is a helpful feature," Turoff says.

The best keto apps will make it easy for you to visualize your daily intake of things like carbs, fiber, and fats, and may even suggest recipes or exercises that'll keep you on track to hit your goals.

If you need a little help finding the perfect one for you, here's a list of the nine best keto apps, as recommended by registered dietitians.

1. KetoDiet (and KetoDiet Basic)

Why it's great for keto: The apps, created by Martina Slajerova, author of multiple books including The KetoDiet Cookbook and Keto Slow Cooker & One-Pot Meals , also offers up a bunch of recipes (300, to be exact) and nutritional info on popular foods, products, and restaurant meals to help you track your keto meals right on your phone.

Review: One person who reviewed KetoDiet in the iTunes app store wrote, "I have to be extremely careful with my carbs for blood sugar's sake. It is so nice to be able to see my day at a glance, and note my trends over time. You can do this with almost any app, but the difference here is the EASE. It is so easy to use!"

2. LifeSum

LifeSum

Not only is this app good for keto, but you can pretty much make it work for any diet plan you want to follow. It helps you keep track of your calories and foods through its food diary and macro tracker, and you can even find keto recipe ideas.

Nisevich Bede also says that the paid version of this app can also provide you with very detailed nutrition info.

Review: One customer who downloaded the app from the Google Play Store said, "Easy to use and value for money—able to track lots of things like water intake, macros, body measurements, and exercise. I love that it has different goals you can set for the week (like vegetable intake), which helps to change your eating habits long term."

You can log your food and exercise right on the app and receive regular reports about how on track you are towards meeting your goals.

Review: An iTunes app store reviewer said, "For a person who is serious about tracking their keto macros, this app does EVERYTHING and it does it WELL. There might be a little effort (5 mins per day) to get your food choices dialed in, but once that's done, the app almost runs itself."

Parekh also likes that app includes fitness trackers and keto recipes.

Review: One person from the iTunes app store said, "The keto diet often feels confusing and counterintuitive, but this app guides you through it every day. It has been fascinating to learn...about the true carb content of various foods. The Find Food section is just incredible."
