Three steps. Your coach or gym already set you up, so there is nothing to search for.
Step 1
Open the email
The subject is your coach's or your gym's name, then invited you to train together. Press Accept invite.
Cannot find it? Check your spam folder, or ask your coach or gym to send it again.
Step 2
Set your password
From a coach: type your email, create a password, and type it again. If your coach charges for training, you then enter your card at their price. That is the only thing you pay.
From a gym: type your email, create a password, and type it again. Nobody charges you here.
Step 3
Sign in and train
Download the app from the link in your welcome email, or sign in on the web, with the same email and password.
Paid your old app through your phone?
Cancel it yourself from your phone's subscriptions screen once you have joined Marrow. Your coach cannot cancel it for you.
Your old workout history
It stays in your old app. You start with a clean log on Marrow, so save anything you want to keep.
