“So I originally built this in lovable back in February and this is when I didn't even know anything about apps”
Editor's note: The founder says he first built the app in Lovable over two months, then rebuilt it before launch with a tool the auto-transcript renders as 'work max' (possibly Rork Max; we could not confirm the name).
How they got customers
Early deals with big fitness influencers didn't work and were dropped. What worked was paid ads on Meta (he cites about 2 to 2.5x return on ad spend) using content from one creator who got equity, then moving the same creatives to TikTok ads, which he says returned 4 to 5x because TikTok reaches his 15 to 30-year-old audience.
Steps to try
Look at app ideas that already work and remix one for a narrow niche.
