DoFasting App Review

DoFasting is probably the best fasting app that is available on the market right now. It is designed to be your guide through a tough process. It walks you through each stage of weight loss and offers a tender hand to guide you as you need it. The personalization options are incredible and offer an experience tailored specifically for you. You won't have to worry about the plan being harmful to your body type or following steps designed for someone else. By taking the app's quiz at the beginning of the process, your experience is your own.

DoFasting's library of fasting plans makes for a comprehensive and effective experience. Expert knowledge on each type of fasting is used to ensure that every user can find the path that benefits them most. If intermittent fasting isn't for you, then perhaps the alternate-day fasting technique will work. DoFasting is one of the few places where you can find almost every type of fasting in one spot.

Zero Fasting

Overall, this is a high-quality app. The content you have access to and the step-by-step instructional videos are certainly worth the price. The feature that really stood out to me was the fast-tracking timer. It makes keeping track of your fasting and eating breaks simple and lets you know what progress you're making. You won't always see the progress on yourself too quickly so having the statistics section showing you your progress is a fantastic addition.

My favorite feature of Zero Longevity is the direct contact it offers. You can submit your questions to a panel of experts who will respond directly and provide you the one-on-one contact that could get you through whatever obstacle you're facing. The advanced statistics are a fantastic way to get into the details of what your body is experiencing. The more you know about how fasting is affecting you, the more you can do to benefit yourself.


  • Easy to use and complies your accomplishments in an easy to read graph.
  • Tons of content to help you understand fasting and its benefits.
  • Brings the science to you and justifies fasting.


  • The full version is pretty pricey.
  • The custom plan seems to be the main reason for the pro version of Zero.

Fastic App Review

Fastic is a modern app created by an experienced team who are ready to help you get started on your intermittent fasting journey. It's a beautifully designed app that offers a sense of joy and simplicity as you use it but really is a complex and thorough fasting program. Its extra features are designed to make fasting easy and accessible to all.

While there are many fasting apps that offer libraries of content and information to learn about fasting, few reach the heights achieved by Fastic. This was my favorite feature throughout the Fastic app review - their academy made intermittent fasting a concept that anyone could understand. After going through the academy, it was clear what intermittent fasting was doing to your body and why it was helping you remain healthy.


  • The academy is one of the best wells of knowledge.
  • You can enter new Healthy Habits and challenge yourself throughout the week.
  • The free version allows users to try out the services before paying.
  • Offers meal and snack recommendations so that you don't overeat or compromise fasting.


  • The community isn't too active.
  • On the expensive end compared to other apps.

BodyFast App Review


If you're looking for one of the most comprehensive and personalized fasting apps available, then BodyFast is the app for you. Throughout my BodyFast app review, I found myself in awe of the customization options available. This app is able to personalize your fasting week like no other and it ensures that the plans you're following are well-suited for your lifestyle and goals.

MyFast Tracker App Review


MyFast Tracker is a fantastic fasting app designed for anyone who needs a buddy throughout the fasting process. It's a dedicated companion with all of the tools you need to find success while fasting. From the fasting timer to the well-designed weekly schedule, MyFast Tracker has it all. Throughout this MyFast Tracker app review, I couldn't help but notice the incredible individuality of the app. It's a unique program that fits specific needs not found in other apps.



Overall, the Simple: Intermittent Fasting and Water Tracker App is both dependable and advanced. It offers tools that you can't find anywhere else, simplicity that works for every user, and a thriving community of fellow intermittent fasters. It's a wonderful app that makes intermittent fasting easy and accessible to all. If you're looking for an intermittent fasting app that is designed to work for you and all of your fasting needs, this is the perfect app for you.

The prices can be steep, but the tools offered are certainly worth it in the end as these are some of the most comprehensive intermittent fasting aids we've seen. They're clearly designed by intermittent fasters for intermittent fasters and offer you what you need to make it through the worst parts of the process.



The amount of content you're getting with the Fastyle Intermittent Fasting Tracker is incredible. From the basic time tracker to the online coaching professional, Fastyle unlocks a wealth of tools that make intermittent fasting achievable. The team behind Fastyle knew what they were doing with every aspect of the app. There is an unbelievable amount of information to be gathered and endless help to get you through the worst of intermittent fasting.

Some of the information provided via the dietary guidelines section of the app is outdated and contradicts advice offered by the personal coaches which can make your periods of eating confusing. Other than that, there isn't much I can say about the app that isn't positive. It's an affordable app that offers quality tools and content to make intermittent fasting easy.

Life Fasting Tracker App Review


Where this app truly shines is the community pages. Users can interact, post their progress, and make friends with others in the intermittent fasting community. It's a fun feature that makes you feel a part of something larger. With Life Fasting Tracker, you're not alone in the journey. Throughout my Life Fasting Tracker app review, I constantly found myself returning to my profile page to see what progress my friends were making.

The tools they offer are pretty standard but quite effective. Though there are other apps that might offer more, Life Fasting Tracker does have plenty of useful information and guides to get you through intermittent fasting. The statistics are easy to comprehend and can be quite useful for tracking the progress of your body.

Window Intermittent Fasting App Review


Where this app truly shines is in its choice of goals. Most apps assume that weight loss is your end goal and tailor their services towards that mark. Throughout my Window - Intermittent Fasting app review I was continuously asked what my end goal was. The app ensures that all sorts of health-related goals can be achieved. Weight loss, more energy throughout the day, fat burning, better sleep, improved heart health, and so much more.

I loved the inclusion that this app offers its users - it's not just one sort of health benefit. If you're looking for a fasting app that isn't designed for just weight loss, then Window might be the perfect program for you. It's a thorough app that is designed to benefit you and to make your time fasting easier.

168 Fasting App


Overall, the 168 Fasting App is a useful intermittent fasting tool that applies to both beginners and veterans alike. The services they offer are comprehensive and pliable, and the communal feel you receive from the app makes the experience well worth the price. The intrusive ads that you have to pay to remove can be quite annoying, and the syncing issues make getting started difficult, but once you're tracking your intermittent fasting, it all becomes worth the effort.
