How do I create a new profile?
The only way to create a new profile is by uninstalling and reinstalling the app. When you reinstall the app from the App Store and open it for the first time, you should be given the option to choose your old profile, or set up a new one. You can then choose to set up a new profile, while all your old entries will be in the old profile if you wish to access them again later.
If you wish to keep the data in your old profile, before uninstalling please check that iCloud sync has been enabled for Progress and choose 'Keep' when you see the Health Data pop up to ensure that your data will be saved.
