Problem
- Isotretinoin treatment is a six-month commitment with a moving dose curve and meaningful side effects. Existing tracking options are a notes app or nothing.
- Reaching people early in their treatment means showing up where they already research, not paying for ads.
Approach
- Shipped the smallest useful version: dose log, side-effect tracker, photo timeline.
- Built a repeatable TikTok content workflow (research-backed slideshows on side effects, treatment timelines, and myth-busting) to grow distribution organically.
- Tightened onboarding based on real drop-off data; iterated weekly.
What shipped
- iOS app live in the App Store with a paid subscription tier.
- In-house video generator for treatment progress videos.
- Side-effect data tracking with per-effect charts.
- 500+ users in the first weeks since launch.
- $300+ in early sales.
- 1,600+ TikTok followers from organic content.
What's next
- Automating the marketing flow for TikTok content generation.
- Exploring UGC for content amplification.
