Best Intermittent Fasting App UK – Free & Paid Choices

Intermittent fasting apps can help with more than just losing weight – they can be used for a wide range of other health benefits too. This includes benefits to your immune system, improved management of inflammation (helps injury recovery), improved blood sugar control and that’s not even all of them.

But as with all lifestyle changes, there is a transition period which is quite difficult. Even if you’re not a newcomer to the lifestyle there are apps out there to make intermittent fasting easier than ever. Let’s have a look at what apps are the best for intermittent fasting.

Best Intermittent Fasting App

Bodyfast Intermittent Fasting – Unique Features

The first app we’ll look at is the Bodyfast Intermittent Fasting app. This one was a big favourite of ours. The tracking itself is almost entirely done for you.

You select a fasting schedule that works for you and the app does the rest, you’ll get a notification when to start and stop your fasts making the lifestyle as automated as possible.

With the coach (paid) version the app really shines. It unlocks the full range of features to be used and also provides a coach that will keep you accountable with your fasting. Something that many people struggle with is motivation and having those “well I’m sure I can take one day off” moments.

With someone there to keep you on track there’s going to be a much higher success rate when it comes to keeping on track with your goals.

Overall, a great app, the downsides would be that the paid version does feel mandatory to get the most out of the app and it is quite aggressively marketed with pop ups inside the app itself.

You can check out our full Bodyfast review for more information why it’s our favourite option.

Zero Fasting – Premium Intermittent Fasting Plans

The Zero fasting app is the next app we’re going to look at. As with the Bodyfast Intermittent Fasting app there is a paid version where you will be getting the real value of this app.

With the free version you’re essentially getting enough to help you a long with a fasting tracker and some other tracking for metrics like weight, activity levels and sleeping levels.

A nice addition that is in the free version is they have an articles section to help educate on the benefits of fasting and a few tips and tricks while fasting.

The paid version of this app is where it really comes alive. With fasting plans made specifically for you and your goals it’s clear that this is how the app is supposed to be used. You’ll get a coach, more specific metrics for you tracking and also new content each week in the form of challenges.

Overall, our verdict is that it’s pretty good. It’s a well made app and goes a long way into making the content specific for you when you get the paid version. That is really the only downside, that the app feels somewhat lacking without the paid version.

There is a 7 day trial available however so can try it out for a week and see if it’s for you – you can also check out our Zero Fasting review first.

Fast Habit – A simple fasting app

Fast habit is a really simple app. This app is your no nonsense here to do what it’s here to do. And that is track your fast.

If you’re more experienced with fasting and are not in need of a coach or all the surrounding info when it comes to fasting, then this may very well be the app for you. The app is very straight forward. You open the app, select how long you will be fasting for. Then, you can get started.

There are a few extra features included with a paid version which is incredibly cheap and only a one off payment rather than a monthly subscription like the other apps.

The downsides of the app is its design. It is very minimalist, so if you’re newer to fasting this may not be what you’re looking for, and you may want something with a greater level of intermittent fasting education included within the app.

But if you’re more experienced and are just looking for an app that will notify you when your fast is up and lets you log your weight over time then this app is exactly what you need.

Overall, it may be very simple, but it does what it’s designed for perfectly. Keeping things simple and easy – read more in our Fast Habit review.

Fastic – Best Intermittent Fasting App for Beginners

Fastic is the final app we’ll look at, and we may very well have left the best until last. The Fastic app is designed in such a way that it is perfect for beginners. It has an in depth questionnaire once you first open the app and really focuses on educating you about fasting.

As mentioned, if you are a beginner this app is perfect. You can try out fasting while learning all the benefits and a few tips and tricks to help you along.

There is as with others a paid version of this app which gets you additional diet plans. It must be said that this is one of the few apps which feels like a complete app with the free version. The paid version is simply the above and beyond for those who want it.

Overall, it’s a solid app. As mentioned, this is one of the few apps in the health niche that feels like a complete app in its free version, which is a huge plus from me. Check our my full review of Fastic for more detail.

Common Questions about Fasting Apps

Are there any free intermittent fasting apps?

The good news is that if you’re looking for a free intermittent fasting app, the majority of intermittent fasting apps will have either a free trial you can take advantage of, or even a free plan to use to see whether the app is right for you. It can be a good idea to try a free fasting app first – then when you know you’re going to stick to it, switch over to a premium version with more features.

Which intermittent fasting method should I follow for weight loss?

There are various different intermittent fasting methods to choose from, but the main benefit of them all is the same when it comes to losing fat – to reduce your overall food intake by eating less. As long as you stick to your eating windows and maintain a consistent eating schedule, any method like the 16:8, 18:6 or the 5:2 fasting diets will be effective.

What are the health benefits of intermittent fasting?

Aside from weight loss, there are other potential benefits of downloading an intermittent fasting app and adjusting your lifestyle. As well as shifting any excess pounds, some people find that intermittent fasting has a positive effect on their blood pressure, glucose levels, heart rate and can overall contribute to a healthier life.


Intermittent fasting has quickly become one of the biggest health trends in the world over the last few years.

Honestly, it’s hard not to see why, there has been a huge amount of research in the area and unless taken to some serious extremes, (which can be said for anything) the results have been incredibly favourable.

Of the 4 apps we’ve mentioned here, they each work very well for the audience they are designed for. Fast habit for example is likely the best app for those who are more experienced and Fastic is perfect for those who are just starting out with tons of extra information.

Bodyfast Intermittent Fasting and Zero Fasting are a nice middle ground. Good for both beginners and the more advanced, it keeps the tracking in place but does it in a way which does still provide information for those who are relatively new.
