Product
They shame you and then they just like reward you excessively for every single move. But they can do this because with language learning you can complete the task inside the app and you can complete it quickly. You can't get a better night's sleep in five minutes in the grocery store line.

Duolingo's shame-then-reward loop works because the task is completable inside the app in 3 minutes — yours may not be

Paloni explains why copying Duolingo's engagement mechanics fails for most health and wellness apps: Duolingo's loop works because the entire beneficial action — closing a language lesson — happens inside the app in 3-5 minutes. The notification shames you into opening, and then fast in-app completion delivers immediate reward. Health outcomes like sleeping more, exercising, or reducing stress cannot be accomplished in-app. Building Duolingo-style streak pressure around actions that require multi-hour offline behavior creates shame with no attainable reward.

Launching
I would find people online journalists that wrote about mental health and then I would read it reach out to them either on LinkedIn or try to get their email and send pitches that way it was a ton of work because not many people would ever respond to me but what ended up happening is every now and then we'd get featured in a pretty major way for small apps so we were in Cosmopolitan we've been in Women's Health we were even in Time magazine.

Cold-Pitch Journalists Who Already Cover Your Niche And You Land Time, Cosmo, Women's Health

Anya hunted down journalists already writing about mental health, found their LinkedIn or email, and cold-pitched her story. Most ignored her, but the hit rate produced features in Cosmopolitan, Women's Health, and Time — outsized payoff for a small app driven entirely by organic cold outreach.

There's a play for whatever you're stuck on.
