## What is Body OS Playbook?

Body OS Playbook is your personal coaching companion — the private app that keeps you and your coach connected between sessions.

Built for clients in the coaching program, it puts everything you need to stay consistent in one simple place:

• Log your weight in seconds and watch your real trend — not the daily noise — with a smart 7-day moving average.

• Upload progress photos to see how far you've come. Front, side, and back, kept private and just for you and your coach.

• Complete your weekly check-ins so your coach can adjust your plan and keep you moving toward your goal.

• Browse the resources and grocery lists your coach hand-picks for you — right when you're at the store or the gym.

• Message your coach directly when questions come up. No more lost texts or scattered emails.

• Get gentle reminders for weigh-ins and photos, so nothing slips through the cracks.

Everything lives in one secure place, on your phone, ready whenever you are. Less guesswork, more accountability, and a coach in your corner every step of the way.

Note: This app is for active members of the coaching program and requires an invitation from your coach to sign in.
