Where this program 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 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.

All of these meals have the perfect mix of balanced nutrition that can help kick start your weight loss. Frozen meals have come a long way, and their team of chefs works hard to make sure they taste as good as they are nutritious.

What to Consider When Choosing Weight Gain Apps?

There are many different reasons why you may need to gain weight, and plenty of apps are available to help you reach your goals. It’s hard to know which are the best, so here are some things to consider when choosing the best weight gain apps.

  • Price: Do you have a budget? If not, then you’ll have more options. If you do, then you’ll want to pick an app that fits your budget. Be sure to factor in different subscription tiers as you budget. What may be too expensive annually may work for you on a six-month or quarterly basis. 

  • Plans: Are you planning on bulking up using a specific plan or strategy? If so, check into the app to ensure that it’s an option as you track your eating habits. It’s all about watching what you eat. 

  • Features: Food tracking is essential in the best weight gain apps, but there are also recipe libraries, support communities, meal planning, and more. Different apps have different features, so make sure you understand what’s available to you and what you plan to use before picking an app.

The best weight gain app is one that you’ll actually use, so you’re not just wasting your money on something that just takes up space.

How We Tested Weight Gain Apps?

We personally evaluated all of the best weight gain apps, assessing the various features, price points, and more to make it easier to pick an app to follow. All apps were assessed using the same criteria for fairness, and they are as follows.

  • We start by reviewing the app, downloading and assessing all the features that are available. We note which are free and which are premium features and all other pertinent information about the best weight gain apps.

  • We list out the prices to help you understand the value you’re getting, including any different payment plan options.

  • We cross-reference other reviews to ensure we don’t miss anything. If they list something we haven’t seen, we go back to the app to understand if the feature is still available. 

  • We contact customer service to assess their responsiveness. If there are multiple customer service options, we test them all.

  • We assess usability. All of this is great, but if the weight gain app is clunky or hard to use, then it’s not worthwhile. 

All of these steps together are put together in a comprehensive review that helps you identify what weight gain app will work best for you. There is no one best app.
