Startup insights
Value proposition

Turns a daily tracking routine that people in this niche already do on paper into a few taps, and gives them something they can bring to their doctor. That medical-visit moment is what drives the upgrade to paid.

Problem solved

Replaces paper logbooks and spreadsheets for a condition people have to track every day, for life. Usage is recurring and non-optional, which is why organic search demand stays stable.

Audience

People managing a chronic condition day to day, and their caregivers

B2C~650 users

Pricing

Freemium: $29.99/year with a 3-day trial, plus a one-time $59.99 lifetime unlock. Pricing and paywall are managed remotely, no app update needed.

Message from the founder
Serafettin Sarisen

"I am simplifying my portfolio. I run several apps and cannot give this one the attention it deserves, so I would rather hand it to someone who will focus on it. What makes it interesting: growth is fully organic from app store search with zero ad spend, there is no backend so running cost is basically the developer accounts, and pricing and the paywall are managed remotely so a new owner can test monetization on day one. Happy to share the app name, store links and full detail under an NDA."
