Apple Health
Keep what you already use.
Your watch and apps already write to Apple Health. Longset reads from it, so your data flows in on its own. No new device, no switching apps.
Model Context Protocol
Plug it into any agent.
Longset speaks MCP. Connect it once and your agent can read your week, move a session or plan tomorrow's food. Your phone updates on its own.

Questions.
What is Longset?
A training app for any long goal, from a first marathon to Hyrox or a full Ironman. It reminds you about every session and every meal, and puts your day on the lock screen so you rarely need to open it.
Where does Longset get my data?
From Apple Health. Your watch and apps, like Apple Watch, Garmin, Strava, Zepp or Oura, already write there. Longset reads your workouts, heart rate, sleep and weight from it, so you keep your setup and never log anything twice.
Do I need an AI agent to use it?
No. You can plan everything in the app. Connecting an agent just makes changes as easy as sending a message.
Which agents work with Longset?
Any agent that supports MCP, the Model Context Protocol. That includes Claude, Codex, ChatGPT, Muse, Hermes Agent, Cursor and Gemini CLI.
What is MCP?
An open standard that lets AI agents use apps. Longset offers tools like "move a session" or "plan meals", and your agent uses them when you ask.
Is it iPhone only?
iPhone first, with lock screen widgets and notifications. Android comes after launch.
