Your tracker scores you. Then changes nothing.
A red recovery ring with the same workout still on the calendar isn't coaching — it's a weather report. Knowing you're tired was never the hard part.

The problem
You already own the data.
You're missing the layer that explains it.
Generic plans break. Then you quit.
The plan doesn't know your Fridays always fail, your sleep slides before hard weeks, or that you respond better to volume than intensity. So it breaks — and takes your momentum with it.
Missing — a plan that learns who it's coaching
Apps guilt you, or let you off. Neither works.
Streak shame burns people out. Endless flexibility dissolves the plan entirely. A real coach does neither — they hold the standard and find the way you'll actually meet it.
Missing — accountability that adapts without going soft
Sound familiar?
The fix is one clear call every morning — founding access from £8.99, locked for life.

One call, with the reasons
The morning brief leads with what to do — and the "why" underneath: HRV down, sleep short, load high. No raw numbers to decode.
Readiness at a glance
Readiness, load and sleep as three rings — the same recovery markers a good coach watches, read in a second.
The week, not the day
Sessions move, get covered, or slot back in. A tennis match can credit a run. You're measured on the week.
