Situation & Challenge
Expectant parents needed a trustworthy hypnobirthing app — guided hypnosis, meditation, and birth-preparation content that still works offline when hospital Wi‑Fi or mobile signal is unreliable.
- •Guided hypnosis and meditation for daily birth preparation
- •Personalized pregnancy journey content
- •Offline access to downloaded sessions
- •Subscription-based premium content without friction
- •Secure handling of sensitive user profile data
What I Built & Why
The app was designed around audio-first wellness flows — streaming when online, cached when not — with careful offline handling so sessions never feel unavailable at the moment they matter most.
- •Flutter UI focused on calm, distraction-free playback
- •Audio streaming with offline storage and download management
- •Firebase backend for user profiles, content delivery, and subscription state
- •In-app purchases for premium hypnobirthing programs
- •Mobile-side changes and offline sync patterns for session reliability
Decisions I Made
Architectural and product choices from production constraints — not hindsight slides.
Offline-first audio and content
Designed download, cache, and playback so expectant parents access hypnobirthing sessions without relying on hospital Wi‑Fi or spotty mobile signal.
Flutter for German App Store and Play Store
Single Flutter codebase shipping to iOS and Android for the German market — one team maintaining both stores instead of native duplication.
Owned mobile and offline end to end
Spent roughly 1.5 years on mobile-side changes, offline sync patterns, and session reliability — not just UI polish on an existing native app.
