Welcome to the Fitbit Community, @Akshi12.
Thanks for the details shared in your post. MobileTrack lets you use the Fitbit app without a Fitbit device by using your phone's sensors to track basic activity data including steps, distance, and calories burned. For more information, see How do I use Fitbit MobileTrack? MobileTrack may add extra steps and I recommend removing it from your Fitbit account if you're not using it: How do I remove a Fitbit device from my account?
Hope this helps!
