ZON Train screen with the week strip, today's session and the to-do list
  • Today's session front and center, with a one-tap start

  • Week strip showing what's planned, done and coming up

  • A daily to-do: check in, train, log your meals

The problem it solves
You open five different apps to know what you're doing today. You waste ten minutes looking for information you should have had the moment you woke up.

The problem with scattered training apps

A notes app for your program, a nutrition app for your meals, another app for your stats. Before every session you juggle three tools, lose the thread and train in degraded mode.

Train Hub ends that fragmentation.

A home screen built around action

Train Hub isn't a dashboard to stare at. It's a daily flow. The moment you open ZON, you see what the day asks of you:

  • Today's session: the workout from your program, a routine you built or a session generated by the AI, with exercise count and estimated time. One tap starts it in the workout player.
  • Week strip: your week at a glance, today highlighted, trained days easy to spot.
  • Daily check-in: a few seconds to rate how you feel, so your readiness score is ready.
  • To-do for today: log your daily metrics, finish your workout, log your meals. Tick them off as the day goes.

Readiness and the AI copilot, one tap away

Your daily brief turns sleep, HRV, soreness and training load into a readiness score with a clear call: push, hold or recover. When the day calls for a change, the AI copilot adjusts the session and explains why. Got a question? Ask the copilot directly from the brief.

Built for athletes who take training seriously

Train Hub is for athletes with a plan and measurable goals who can't afford to waste a session because they didn't have the right information at the right time.

When context is clear, performance follows.
