“Strava gives you a little badge you can put on your social media whenever you do something well. So we make a lot of our content shareable. A friend started sleeping better and posting Welltory's magical fuel tanks on social media to brag to people — that helps people come back to your app for more content to share.”

Bragging rights are an underrated retention driver — make your best moments shareable

Paloni highlights that users sharing app content to social media creates a secondary retention loop: the desire to have more shareable moments brings them back. Welltory makes its animated health visualizations shareable as a deliberate product choice. Strava's route maps and Duolingo's achievement badges serve the same function. The mechanism is self-reinforcing: a user brags, their network sees the brag and downloads the app, and the original user returns to generate more shareable content. This is one of the few organic distribution channels that costs nothing to maintain.
