When choosing the right app for you, Prest suggests thoroughly reviewing the features and fees associated with each one to make the right decision. However, “the most important feature would be a timer that reminds you when to eat and when to fast,” Gans says. Everything else is just a bonus and should be selected based on your unique needs.

Depending on your goals, certain apps are likely to stick out to you over others. For example, if you’d like to lose weight, Window or another app with a weight tracker might be a good option. Or if you feel you need assistance in tracking your meals, Ate Food Journal is likely the way to go.

Considering the cost is often an important deciding factor as well. While most apps offer free trials for their premium plans (which is a great way to try a few different options out!), you’ll need to determine if you can factor any potential cost into your monthly or yearly budget.
