Can’t currently share a contact with MyReach
Hi Thomas thank you for your message.
We are working on some major improvements regarding contacts! One of which is the ability to share your contacts straight to myReach as well as import them in bulk from your phone in just one click!
Will make sure to keep you posted as soon as we have it ready for release!
Good news - Contacts import is available on the App! 
You can integrate your contacts by going to:
your profile (bottom right of the screen) > Integrations > Add Integration > Import Phone Contacts
