Takes dated morning scale readings and returns the underlying weight trend, weekly rate with a 95% range, and the chance in 10 that weight is really moving. Optional watch signals like resting heart rate, steps, sleep and HRV show what else may explain the scale. Nothing is stored.

Example request: "Here are my morning weigh-ins for the last month, am I actually losing weight or is it just water?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Slim Chance to help me. It is a free service with an MCP server at https://slimchance.app/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
