The Challenge
Manual note-taking pulls people out of meetings. The client needed a mobile-first product that could reliably capture audio, handle longer recordings, and turn them into useful summaries and action items without depending on a heavy custom backend.
Key requirements:
- Reliable capture: Mobile audio recording that could cope with longer sessions.
- Useful outputs: Summaries, action items, and note interaction after processing.
- Local-first handling: Storage and offline resilience with reduced backend dependence.
QPOI's role
- Mobile audio capture workflow
- Gemini integration for transcripts and summaries
- Local file and storage management
- App store publishing and subscription setup
Core features
We built a local-first mobile app that combined recording, summarisation, note interaction, and subscription-ready product logic in one workflow.
AI-assisted meeting processing
We built a service layer that prepared recorded audio for analysis and integrated with Gemini to produce transcripts, summaries, and follow-up outputs.
Chat with your notes
Users could ask follow-up questions about a meeting after the transcript and summary were generated, making each note more useful than a static summary alone.
Resilient File Management
Recordings were stored locally with recovery logic for interrupted sessions, helping the app behave more reliably under real mobile conditions.
Subscription Architecture
RevenueCat integration supported freemium and pro plans, feature gating, and usage limits needed for a launch-ready app.
Outcome
Delivered an MVP for iOS and Android
Combined recording, summarisation, and note interaction in one mobile workflow
Kept backend complexity lower through a local-first architecture
Added monetization and store-readiness features for launch
Mobile Engineering Fundamentals
Performance-aware mobile workflows
Real-time calculation of recording duration and file size to manage storage quotas.
Permissions Handling
Smooth flows for Microphone/Storage access, handling "Deny" states gracefully.
Store Compliance
Managed submission for iOS & Android, including ATT privacy compliance.
