    I built Gravitas Crunch for iPhone.

    It turns the sources you follow into a personal radio station. The app reads from real sources, distills them into clear narration, and plays them back as a continuous stream.

    The product is built around on-device AI, so the experience is not dependent on metered cloud usage. The reason you can press Play is because the AI is running on your iPhone.

    Features include:

    - Gravitas Radio for feed-based listening

    - Research Assistant for source-grounded takeaways and drilldown

    - Discover Assistant for finding curated articles and feeds

    - Focus mode for prompting an entire source, like a full article, PDF, or EPUB, in one context-aware session

    - imports for articles, feeds, PDFs, EPUBs, and more

    - high-quality narration with PocketTTS

    - a growing Audiobook mode for long-form sources
