Morning readiness

Readiness is an optional morning signal that reflects how recovered you are. Runsei learns your personal baseline first — a readiness read only means something once it knows your normal, so the first several mornings show "learning your baseline."

What it asks you for depends on what you wear. If you have a source connected that measures overnight (Apple Health today), your sleep, HRV and resting heart rate arrive on their own and the morning check-in only asks the one thing no watch can measure: how you feel. If you measure by hand, it offers those fields. And if you told us you don't wear anything overnight, it never asks for numbers at all — how you feel is a real signal in its own right, not a fallback. You can change that answer under Profile → Morning check-in & readiness.

Every signal is read against your own normal, never a population range — a 30-day median that excludes the most recent week, so a hard block cannot quietly redefine what "normal" means for you. What each signal actually tells you is covered separately: HRV, resting heart rate and sleep each have their own article.

How the score is put together. Each morning's HRV, resting heart rate, sleep and (when you log it) how you feel are compared with your own last 30 days and combined, weighted toward the physiological signals. The scale follows the convention used in HRV-guided training research and the major recovery platforms: values within your normal range mean "train as planned" — that's Ready, the default state of a healthy routine. Prime needs your signals to sit clearly above your usual; the caution bands appear only when they sit clearly below it. So an ordinary morning reads Ready, not average.

Readiness is guidance, not a command: a low reading is permission to soften a session, not a reason to skip training.
