The creators of Fastyle have clearly put thoughtful consideration into each aspect of the app, providing a treasure trove of information and extensive support to guide you through your fasting journey.

One aspect that could use improvement is the dietary guidelines section, which contains some outdated information that occasionally conflicts with advice from the personal coaches, leading to potential confusion during eating periods.

What to Consider When Choosing Fasting Apps?

There are a lot of different fasting apps on the market, so it can be difficult to know what to consider when you’re trying to narrow down your options. Here are some questions you can ask yourself to help you choose.

  • What’s my budget? There are free apps available, but most of the best features are locked behind a paywall. You get what you pay for, so they’re worth the investment, but it’s important to set your budget before you drill down deeper so you’re not disappointed. 

  • Is there a certain plan I want to stick to? Most fasting apps let you choose which type of intermittent fasting you will do. However, if you’re looking for a highly specialized type of fasting or diet, you’ll want to check if it’s available in the app. 

  • What features do I plan on using? Timers and food and water logs are standard in most fasting apps, but if you’re looking for active social communities, recipes, coaches, and more, you’ll need to investigate a bit more. Each app offers different features, and some are more active than others.

The best fasting app is going to be one that meets your needs, so don’t get distracted by the bells and whistles. 

How We Tested Fasting Apps?

  • Cross-referencing other reviews, comparing to see if we missed anything, if features are no longer available, and to see if anything changed to have the most comprehensive reviews available.

  • Contacting customer service to understand the ease of troubleshooting, including testing the email, chat, and phone assistance where applicable.
