What the coach does
- Builds your week from your goal, the days you can train, your time and your equipment.
- Remembers what you did. Every logged set shapes the next session, so weights are measured, not guessed.
- Changes the plan when life does. Less time, a busy gym, a missed day or a trip: say what changed and it rewrites the session or the week.
- Answers in plain language, any hour.
It does not watch your form, diagnose injuries or replace medical care. See how the plan adapts.

The plan is free. The coach is the membership.
The plan is free: your week, every workout, your logbook and history, every new week, and one exercise swap per workout.
Coach chat, the morning check-in and changes to your week are the membership. Coaching is $3.49 a week, $9.99 a month, or $59.99 a year on annual, which opens with seven days free.
The free plan arrives with app version 1.0.6. Until then, workouts in the app need a membership.
Questions
What is an AI workout coach?
Software that plans your training from what you tell it and what you log, and explains its changes. Aion does this on iPhone. It is not a human trainer or a medical service.
Does Aion watch my form?
No. Workouts come with cues and videos, but Aion does not record or review your lifts. For technique feedback, train with a qualified coach.
Is Aion on Android or the web?
Aion is an iPhone app. The free workout plans and the workout adapter on this site work in any browser.
Can Aion replace a personal trainer?
It can plan your week and adjust it when life changes. It cannot watch you move or clear an injury. Many people use both.
