FAQ on Intermittent Fasting Tracker Apps

Is there an app that is completely free?

We do have a totally free app, which you might be looking for. Fasting Hero allows you to use all features for free, but it has one drawback that most of you will mind: all of the features it includes are too basic. You can simply use it to keep track of your fasts and weight. Based on my personal experience, I recommend using the free versions of other apps that offer a diverse range of essential features. Take Litely for an example, you can access insights into your fasting progress, weight, and exercise without paying a dime. In addition, the Live feature, which offers peer support and daily motivation, is also available for free. So, instead of searching for a completely free app, consider using the free versions of other apps that offer diverse and essential features. You might be surprised to find that they work just as well.

How do I know which app is best for me?

Almost every app help you track your personal data, but they varies in other respects. When choosing an app, you should understand your needs and goals. For example, if you are someone who want to get personalized advice, you can try Simple. The Simple trackers give you insights into your eating and drinking habits.
