A solo founder is starting to break out on Instagram and TikTok with UGC-style app content.
Koda: Cozy Self-Care is a soft, Ghibli-inspired mood and habit tracker built around comfort and aesthetics rather than productivity pressure.
Launched two months ago, the app has already generated around 500K views, an early sign that the calmer, aesthetic-first self-care niche is resonating.
What makes the growth more interesting is who is driving it.
The app is being promoted by its founder herself, through @reb.ponyo on TikTok and Instagram. But instead of leaning into classic founder-led content, she is testing hooks and formats that feel much closer to UGC, especially Gen Z-coded reaction videos with strong visual payoff.
She is essentially acting as her own ambassador.
So far, the clearest winner has been one repeated hook:
"i love being a girl in 2026 cause why is this studio ghibli self care app so cute"
The best-performing version hit 240K views, 7.2K shares, and 4.3K bookmarks on April 9.
The format is simple: shocked reaction first, then a quick demo of the app.
The Ghibli-style visuals do most of the selling, while the hook frames the product in a way that feels highly native to gen-Z girls. The comments were filled with people asking for the app name.
A few days later, on April 14, she repeated the same strategy and hit another 108K views, plus 1.8K shares and 2.8K bookmarks.
The app is still in its early days, but it already ranks among the top 200 in Germany & France for Health & Fitness, including a top 100 ranking in 4 countries.
So far, the early lesson is clear: one founder, one strong visual identity, and one repeatable UGC-style hook were enough to prove there is real demand here.
It also seems like she took the winning hook inspiration from Shelf, who recently went viral with “I love being a girl because (…)” style hooks.
Now that the signal is there, the next step is scale.
