Best answer: Nope — anyone can step on the scale and it'll give you an accurate reading. If you want to keep track of your weight, you'll need the Fitbit app on your smartphone. To get the most out of the Aria, however, a Fitbit fitness tracker like the Versa connects with even more features.

You don't need a Fitbit: just the app

While it seems like you might need to have a Fitbit to use a Fitbit-friendly scale, in reality, all you need is the app.

While the app is keen on keeping track of your weight day in and day out, even if you don't have the app, you'll still be able to step on the scale and have your weight displayed without an issue - but we do recommend downloading it if you pick up your Fitbit Aria 2 to get the most out of your smart scale and weight loss journey.

Using the Fitbit App, you can track and monitor your weight gain and loss and log even the slightest differences in your body changes. Simply step on the scale and your Fitbit app will automatically receive your weight at that moment, logging it so you can compare your body mass form day to day.

A Fitbit is a terrific fitness accessory to consider

Although it's not necessary to have a Fitbit in order to use a Fitbit Aria 2, having a fitness tracking wearable is always a beneficial and convenient tool to have wrapped around your wrist.

Most Fitbits are waterproof, track your sleep schedule, allow for female health tracking, and depending on the model you end up going with, can do so much more to custom-fit your day-to-day life style.

The Fitbit Versa is a sleek, smart, and incredibly stylish fitness accessory that tracks your daily steps, sleep cycle, caloric intake, female cycle, heart rate, and so, so much more.

You get a whopping four-day battery life with the Fitbit Versa, and the device itself is both swim proof and boasts 15+ different exercise modes, so whether you're biking, sprinting, lifting, skating, swimming, skipping, jogging, or all of the above, the Versa has you covered.
