Show HN: A simple to-do app for iPhone, Mac, and your agent

Nagare is a new to-do app for iPhone and Mac that combines calendar events and tasks into a single unified list, allowing users to see how timed and untimed commitments fit together throughout their day. The app emphasizes simplicity with a minimalist design and integrates with iCloud for syncing, while also connecting to AI agents through MCP to provide proactive assistance based on your plans and goals. The creator developed it to solve the limitation of existing apps that kept calendar events and tasks separate, making it harder to visualize how daily commitments interrelate.
