Doof's tactic

Doof · B2C · food mood diary app

Reuse your proven meme slideshow for a new app, naming it only in the caption
One post hit 5M views; app reached $1,000 in its first 30 days

Doof was built as a public challenge: make a mobile app in 30 days and take it from $0 to $1,000, marketed on Instagram, TikTok and Twitter. After a week of trying new formats with nothing popping, Jack went back to his tried-and-true slideshow format with a food meme ('people who eat like this feel good, sleep good, and poop good') and the app only mentioned in the caption ('feel good today by downloading Doof'). Goal: content that doesn't look like an ad. Used a standard Superwall paywall template.
