Mobile App Development for Fertility Tracking App – “Sintonía” (iOS)
Budget: $750 – $1,500 USD
Hi! I'm developing Sintonía, a mobile app designed to help women understand their fertility and increase their chances of getting pregnant through natural methods and personalized support.
The core goal of the app is to provide a space where users can track daily fertility signs (biomarkers) such as cervical mucus, basal body temperature (BBT), and emotional or physical symptoms, and then receive personalized daily feedback about where they are in their cycle and what steps may help them improve their fertility. All of this is oriented toward women who are actively trying to conceive.
This is a university-based UX project, now moving into its MVP development phase. I’m looking for a developer (or team) who can build the iOS version only, ideally using React Native or Swift. I’ll be providing a fully designed prototype in Figma, including screen flows, copy, branding assets, and a design system.
User onboarding with personalization: input cycle data, symptoms, pregnancy goals, medical history, etc.
Daily recording (tracker) for cervical mucus, BBT, and other optional biomarkers. Simple and intuitive UI.
Daily fertility feedback: after recording, the app shows the user what her biomarkers mean (e.g., "You’re in your fertile window", “BBT has not yet risen”), always framed in friendly, non-medical language.
Cycle calendar: view recorded data, fertile days, and cycle predictions in a visual calendar.
Educational module: static pages with short articles about fertility awareness and cycle health (provided by me).
1:1 virtual advisory: users can book a personal fertility session with a real coach. The session is done outside the app (Zoom or Meet), so for now, the app only needs to include a booking flow: users request an appointment, get assigned an advisor, and receive confirmation and calendar integration.
Profile section: shows user’s data (plans, preferences, medical notes, etc.) and allows notification control.
Freemium model: free version includes basic tracking and education; paid plans unlock coaching sessions and full insights. No need to build subscription logic now — just placeholder screens.
