Pillarium

Pillo is a medication and supplement tracking app that helps users stay consistent with their health routines through scheduled reminders, simple logging, and a clean interface. It has an active subscriber base generating recurring revenue, with subscriptions managed through RevenueCat. What makes Pillo stand out is that every single download has been 100% organic - no paid ads, no paid acquisition, no marketing spend. Users find the app on their own through App Store search and word of mouth, and they convert to paying subscribers and stick around. That's a strong signal of genuine product-market fit and built-in retention. Built with Flutter, the codebase is cross-platform ready - currently shipping on iOS with a clear path to Android.
