Due to a very unfortunate design oversight, you only show to your friends what you are doing. But they have to create their own habits so nothing is shared. Imagine 5 people trying to share and send 10 habits all over the place its a mess of people manuallu REcreating 50 habits and then sharing hem back. S E R I O U S L Y? . whatsapp or google docs is better then. The smarter thing would be when you as the master share with your friend your habit, a simple button allows them to add to their own collection so the habit really is shared. Until then this group lacks integrity calling it habit sharing.
