Why it worked
The video leverages a relatable aspiration (getting a new phone) and connects it to a tangible reward mechanism (earning money by walking), creating a sense of achievable success and incentivizing engagement with the promoted app.
Summary
The video shows a person using a purple app that rewards them for walking, implying this app has funded the purchase of a new iPhone. The footage transitions from showing the app on a phone to the person buying a new iPhone at a store.
