Works with
px works with Concept2.
Every row, ski and ride you log to the Concept2 Logbook counts toward today’s load in px, and tomorrow is planned around it.

What changes
The day is decided with it in view.
Yesterday counts toward today. The session Concept2 recorded is part of your load, so tomorrow is planned around what you actually did, not what was on the plan.
Move, Mind and Fuel, decided together. Your training changes what you eat. Last night’s sleep changes today’s session. One coach makes the call, every morning, and gives the reason.
Ask px, any hour. Text or talk. px answers from your plan, your sleep and your pursuit, and changes the plan if the answer calls for it.

Questions
Do I need Concept2 to use px?
No. px works with just your phone. Concept2 adds workouts, which lets px read your day more closely, but the plan, the coach and the food work without it.
Do I keep using the Concept2 app?
Yes. px reads what Concept2 shares and turns it into the day’s plan. Nothing about how you use Concept2 changes.
What if Concept2 has not synced this morning?
px does not guess. It uses what it has, tells you which inputs are missing, and asks you for the rest. You see a gap, never an estimate.
Is my Concept2 data sold or used to train AI?
Never. It coaches you and nothing else. You can export, pause or delete it whenever you like, and px only asks for what it needs to coach you.

Concept2 measures. px decides.
