Hello, worm

Mistress is a training app for cyclists who need someone to tell them what to do. She reads your sleep, heart-rate variability, resting heart rate and training load, checks your calendar and the time you've sworn to give her, and assigns the session you will ride today.

Her sessions land in Rouvy, Zwift, Garmin, Wahoo and on your Apple Watch. Accept, plead or defy — she remembers either way.

Mistress runs on Mac, iPad and iPhone, and is invite-only for now.
