I’m ready to launch a simple, elegant period-tracking app inspired by Flo and Clue, but trimmed down to the core experience. The entire focus is on helping users quickly log their cycles and symptoms and then see clear fertility insights—all without the friction of creating an account or logging in. Here’s what must be inside the first release: • Period calendar that lets users add, edit, or remove cycle dates and automatically highlights the current phase. • Symptom tracking with a friendly picker (cramps, mood, flow, and a few custom fields I can tweak later). • Fertility predictions calculated from stored history and surfaced on the calendar and a discrete insights screen. No user accounts or cloud sync for now; every record should live securely on the device with local storage. The app has to run smoothly on both iOS and Android. I’m open to React Native, Flutter, or Kotlin/Swift side-by-side—whichever you’re most efficient with—as long as the end result feels native and performs well. Deliverables • Complete source code with clear, documented logic for cycle and fertility calculations • One TestFlight build and one signed Android APK for review • A concise README covering build steps and how to adjust symptom lists or prediction settings I’ll supply the color palette, basic icons, and any copy. A quick Figma-level wireframe review before development begins will help us stay aligned on UX. If you have experience shipping mobile health or habit-tracking apps and can hit these essentials, let’s get started.
