InnerSeasons

A gentle place to check in, track changing days, and talk with your companion.

Comment

Inspiration Perimenopause and menopause are too often treated as taboo or purely clinical. Women experience sweeping changes in energy, mood, and sleep, but most health trackers treat every day in isolation—forcing users into endless manual data entry. We wanted to build a "gentle companion"—an app that understands the seasons of a woman's body and proactively reaches out, rather than just being a sterile medical log.

What it does Inner Seasons is an AI-powered wellness companion designed specifically for perimenopause and menopause. • Frictionless Tracking: It securely syncs daily biometrics (HRV, skin temperature, sleep) via Health Connect, so the app knows how you're doing without you having to type a word. • Proactive AI: You can chat with "Sage," your AI companion, about your symptoms. Thanks to our OneSignal integration, Sage doesn't just wait for you to open the app—she proactively reaches out with personalized push notifications to check in on you. • Wellness Space: Users can explore a library of restorative frequencies (optimized for relaxation and clarity) and interactive podcasts covering hormone tracking and menopause management. • Premium Insights: Powered seamlessly by RevenueCat, our premium tier unlocks advanced hormonal forecasting and deep pattern detection (e.g., flagging nighttime temperature spikes as possible night sweats).

How we built it • Frontend: React Native and Expo (EAS). • Subscriptions & Entitlements: RevenueCat handles our entire paywall logic, entitlement verification, and subscription state, allowing us to gate premium AI insights effortlessly. • Push Notifications: OneSignal drives the proactive AI check-ins, allowing the system to securely route users straight into personalized check-in flows. • Biometrics: Health Connect API for seamless integration with wearables (Samsung Health, Galaxy Watch, Oura). • Intelligence: Advanced LLM integrations power the conversational AI, strictly bounded by medical disclaimers to ensure safe, non-diagnostic empathy.

Challenges we ran into Handling Android 15 edge-to-edge UI updates, securely managing local biometric data without compromising user privacy, and ensuring the AI stayed within strict, non-diagnostic medical boundaries. Calibrating the OneSignal push notifications to trigger based on AI-detected patterns (rather than annoying, generic daily reminders) required deep architectural planning.

Accomplishments that we're proud of We are incredibly proud of the frictionless nature of the app. By tying Health Connect directly to the AI's context window, the user doesn't have to manually type "I slept poorly." The app already knows your HRV dropped, and Sage proactively reaches out via a OneSignal push notification to offer grounding exercises from the Wellness Space. We've built an app that actually feels alive.

What we learned Integrating RevenueCat saved us days of backend billing logic and receipt validation, allowing us to focus entirely on the AI and the user experience. We also learned how to fine-tune AI system prompts to be empathetic and supportive rather than purely clinical.

What's next for Inner Seasons We have a massive roadmap ahead! First, we are expanding our OneSignal integration to create fully offline, agentic background loops—allowing the AI to orchestrate multi-day care plans. Secondly, we plan to introduce 3D, dynamically animated AI avatars that can change their facial expressions in real-time based on the sentiment of your conversation.
