Unfortunately, the Muscle Booster app does not currently offer the opportunity to fully reset your settings.
However, you can change some settings for your account manually. To do this, navigate to Settings within the top-right corner.
Here, you will see your Personal Details.
When you open Personal Details, you’ll be able to change your name, gender, height, weight, target weight, units, and date of birth, as well as the email address associated with your account.
