Community: Feed, Groups, Challenges & Your Partner
How the social layer works: what is shareable and what never is, plus groups, forums, challenges and accountability partners.
The social layer is optional, and none of it is on by default in a way that exposes anything you did not choose to share. It is worth knowing where the line sits before you post anything.
The privacy line
This is the part to read even if you skip the rest. Workouts, meals, PRs, check-ins and achievements are shareable. Bloodwork, vitals, compounds and contest-prep detail are always completely private and never appear in any shareable format, whatever your settings say.
That is a structural rule rather than a default you could flip by accident. On top of it, your profile has its own visibility setting (everyone, anyone with the link, followers only, or nobody), and each post carries its own public-or-followers choice.
Health data has no share switch
There is no setting that makes bloodwork or vitals postable. If you go looking for one and cannot find it, that is the design.
The feed
Chronological, from the people you follow. No ranking, no algorithm, no suggested-for-you. Some posts you write yourself; others the app offers to draft when something happens worth sharing: a new PR, an achievement unlock, a rank-up. Every one of those is a prompt you can decline.
You can like and comment. There are no direct messages: coach conversation belongs in the coaching layer, not a parallel inbox.
Groups, forums and challenges
Groups are the smaller rooms: a training crew, a gym's regulars, people working toward the same thing. Forums are the wider ones, seeded by category (Training, Nutrition, Supplements, Progress, Form Checks, Off-Topic) with threads, one level of nested replies and upvotes. Reading a forum needs no account at all; posting does.
Challenges are time-boxed and can run across your followers or inside a group. They read from what you are already logging, so joining one does not add a second thing to keep up to date.
Accountability partners
The rest of the social layer is audience mechanics: follows, a feed, a leaderboard. A partnership is the one relationship you train with somebody in, rather than in front of them.
It is free for everyone, deliberately. Gating the buddy behind a paid tier would undercut the thing the product is named after.
