Zero's tactic

Zero · B2C · intermittent fasting app

Send a weekly recap of the longest fast with a button to tweet it

People did tweet it; the feature was later dropped

Zero sent a weekly digest showing your longest fast with a prompt to tweet it, and let users take a picture after breaking a fast to share on social. Users share because they get to brag.
