Put Coherence Daddy on your phone

No app store. Nothing to download. You add this site to your home screen once, and it opens full screen like an app — with the face icon right next to your other apps.

On a computer? Open coherencedaddy.com on your phone, then follow the steps below.

  1. Open coherencedaddy.com in Safari.

    It has to be Safari — other browsers can't add icons on iPhone.

  2. Tap the Share button.

    The little square with an arrow pointing up, at the bottom of the screen.
