You may change your email address at any time in the RunPee app. From the Movie List Screen (startup), simply tap on the menu icon at the top-right and a drawer will slid out.
By default the drawer shows “App Settings” options. Tap on “User Options” at the top and then you’ll see “Change Email Address”.
From there just enter the new email address you want to switch to and submit. The RunPee app will send you an email with a verification code. Go to your inbox, get the code, input it, and you’re done.
Please contact [email protected] if you have any issues.
