You can only change your DARE app account's email address if you signed up with an email. If you used Facebook, Google, or Apple to register your DARE app account, you can't change your email address in the app because it's linked to those accounts.
That said, here's how you can edit/change your email address:
1. Open the DARE app
2. Tap Profile (bottom right of the app)
3. Tap Edit Profile (top right of the app)
4. Make changes to your email information via the third field that shows your current email address
5. Tap the Update Profile button
