A sustainable cadence, rooted in your real data.

Kadens guides each day, plans and reviews each week, and checks the focus each month — reading what Strava, Garmin, and Oura already record, and turning it into one plan built around your history and where you honestly are. Run, lift, ride, or climb — the cadence is the same. One focus at a time.

Three lenses · one engine

Day, week, month — the same plan at three distances.

A focus sits above them all — what you're working on now, changed on event, never on schedule. Each lens shows that focus at its own angle.

Today
The day, decided.

The day's session and the reasoning behind it, how to fuel around it, and one honest read on how it went against the plan. Not a grid of metrics — the starting point and the result.

Week
The working unit.

The plan as a ledger — tap a session done or not. Every Sunday the review drafts itself: confirm the record, answer any drift, log the metric, approve next week. Replan any day; life happens.

Month
The reflection heartbeat.

Once a month the quiet progress becomes visible: how the month actually ran, whether the focus is still right, and one thing to keep. It reflects — it doesn't force a decision.

The coach

The coach is the core of the product — every screen is just a lens onto it.

Ask it anything. It reads your day, week, activities, and metric trend through the same tools every screen uses — and it knows your history, not a generic acute-to-chronic ratio.

It never writes behind your back. Every plan change is a proposal you confirm or dismiss. Nothing is written until you approve.

Tuesday's easy run ran hot — 12 min in Z4. With your Achilles history I'd keep Thursday genuinely easy. Want me to soften it?
Proposal · replan_week
Thu: threshold → easy 40 min. Rest of the week unchanged.

Connected

Sits on top of what you already use.

Execution and raw tracking stay where they are. One activity source at a time, synced on connect, on demand, and otherwise on a clock your plan sets.

Strava

Connects via OAuth. Time-in-zone computed from your heart-rate streams against your own thresholds.

Garmin

Signs in the way Garmin's own app does, then brings daily wellness — last night's sleep, resting heart rate, weight.

Oura

Wellness-first via OAuth — sleep, sleep score, resting heart rate, backfilled ~90 days so baselines mean something.

Your calendar

Subscribe once and the plan sits beside everything else you've got on. It reads one way — it shows the week, never changes it.

Your AI tools, over MCP

Add Kadens as a custom connector and the coach comes with you — same tools, same confirm-before-write.

On your phone

Installs to the home screen and runs as its own app. Push knocks when the review is ready — just the knock, never the content.

One focus at a time. Logged weekly, judged monthly. Built for a handful of known users — never a crowd.
