If you’re finding yourself losing motivation to continue on your weight loss journey, you’re not alone. Weight loss can be challenging and as we all know, it doesn’t happen overnight.

Maybe you’ve been inspired by the results you were seeing at the beginning of your weight loss journey and just need a gentle push to keep going. Or maybe you’ve been at it for a while and feel frustrated that your weight loss is starting to plateau.

No matter what the case is for you, there are lots of weight loss apps out there that are designed to hold you accountable to your journey. Whether you’re a beginner or not, using a weight loss app can be great for goal setting, accountability, and taking a data-driven approach to weight loss.


Read on to learn more about the eight best weight tracker apps that can guide you in making your weight loss goals a reality.

How To Choose The Best Weight Tracker App For You

Every weight loss journey is unique to the individual. That means that what’s helpful in a weight tracker may also look different from person to person. 

Some apps take a diet-focused approach, and others may put more of a focus on their fitness tracker functionality. If you are someone who may benefit from dietary support, you may want to look for an app with food logging capabilities and a food database that allows you to track your daily calorie intake.

On the other hand, if you need a hand with your fitness, other apps may sync with wearable devices like an Apple Watch to help you monitor calories burned, activity levels, and heart rate data, to keep you accountable.

So, when choosing the best weight tracking app for you, it’s important to start by identifying what your ideal weight is, what your fitness goals are, and what kind of dietary support may be most beneficial for you.

So without further ado, let’s explore the eight best weight tracker apps available for iOS and Android that may help you make progress towards your weight loss goals.
