  • References to a paid Health+ service indicate AI‑powered health coaching targeted for spring 2026 alongside longer‑term sleep tracking expansions across Mac and iPad flagged for 2027.
  • Siri appears slated for a major upgrade using large language models, with code strings pointing to new planning tools and deeper Spotlight search and answering capabilities.
  • AirTag 2 entries tagged “AirTag2025” cite Phone Finding and Watch Finding modes, improved Bluetooth performance, clearer battery reporting and enhanced crowdsourced location data.
