The Post
Hi r/SideProject! Just released my second app after designing + building for ~6 months, alongside working as a resident doctor.
The app tracks fibre (fiber) plant foods and bowel habits, and calculates you a gut score. No, it doesn't count calories. Yes, you can analyse your poop with AI.
It's far from perfect atm, but it's live. After trying too hard to perfect my last app (it failed), I'm trying to ship faster on this one.
Why this launch worked
The success of this launch stems from the founder's relatable journey as a doctor building a side project, combined with a clear articulation of a unique and intriguing app concept. The target subreddit provided a receptive audience, and the founder's transparency and humor fostered positive sentiment and encouraged early feedback.
What Worked
1
Leveraging a niche subreddit (r/SideProject) for targeted audience engagement.
2
The founder's unique background as a doctor adds credibility and a compelling narrative.
3
A clear and concise description of the app's core features and value proposition (fibre tracking, AI poop analysis).
4
Transparency about the app's current state ('far from perfect atm') and the lesson learned from a previous failed app ('trying to ship faster').
5
The inclusion of a humorous and relatable GIF, alongside a slightly self-deprecating tone regarding the 'fiber' spelling, created engagement.
