Coach Mo is a conversational AI fitness companion. To make the most of it, here’s an honest look at where it shines and where it doesn’t.

What Coach Mo can do

Have a conversation. Ask questions about fitness, motivation, your activity, or just vent about a rough week. Mo responds in your chosen persona. Remember things about you. Mo has a long-term memory system called Files that stores what you’ve told it: your goals, habits, preferences, things that have worked, things that haven’t. Files persist between conversations. Look up what’s in its memory. Mo can search its own memory while you’re chatting to pull up something you told it weeks ago. You don’t have to remind it every time. Adapt to your persona choice. Pick from Default, Drill Sergeant, Hype Man, Big Sibling, or Sports Analyst. Each one frames the same advice in a different voice. Give you a roast on demand. Switch to roast mode for a sarcastic, irreverent take on your week. It’s the same Mo, with the gloves off. Generate your Weekly Mo Report. Every week, Mo writes a personalized recap of your activity and progress, delivered as a slide-style report on your Home screen. Surface contextual insights. When you’re viewing a competition, your activity, or your achievements, Mo may show a quick inline card with a relevant observation, without you needing to start a conversation.

What Coach Mo can’t do

Take actions in the app for you. Mo can talk about your competitions, but it can’t create one. It can suggest a goal change, but it can’t change your goals (you do that in Profile → Today’s Activity). It can’t send messages, invite friends, or change settings on your behalf. Generate workout programs. Mo gives general fitness guidance, not structured workout plans with sets, reps, and progressions. For programmed strength training, use a dedicated tool. See data outside its memory. Mo only knows what you’ve told it (stored in Files) and what’s in the current conversation. It doesn’t read your raw HealthKit data, your private workouts, or anything you haven’t shared in chat or set up in Files. Give medical advice. Mo is a coaching tool, not a doctor. It will not diagnose conditions, prescribe treatments, or replace professional medical guidance. Modify what other people see. Mo only affects your experience. It can’t push messages to your friends, send things to a competition group chat, or change anything in your friends’ accounts. Remember other people’s data. Mo only has memory of you. Your friend’s Coach Mo is completely separate, with its own memory of them.

Best ways to use Mo

  • Be specific. “How should I pace my Move ring today given I’m behind?” gets a better answer than “what should I do for fitness?”
  • Build up Mo’s Files. The more Mo knows about you (goals, barriers, what motivates you), the more useful its advice becomes.
  • Ask Mo to look things up. “What did we decide last month about my running plan?” works — Mo will search its memory.
  • Use roast mode when you need a wake-up call. Default mode is supportive; roast mode is not.

What to do if Mo gets something wrong

Tell Mo directly. “That’s not right because…” — Mo can correct itself in the same conversation. If you need help with something Coach Mo can’t do (bug reports, account issues, billing questions), chat with our support agent Mo at movetogetherfitness.com. The support agent has different tools and a different scope — it can take actions on your account that Coach Mo can’t, and it doesn’t use your Coach Mo weekly allowance.

What about privacy?

Your personal information doesn’t reach Anthropic (the AI behind Coach Mo). Your name, friends’ names, email, and username are all redacted to placeholders before any message is sent, and stitched back in on your device when Mo replies. For the full breakdown, see AI and your data.
Coach Mo is an AI assistant, not a certified personal trainer or medical professional. It gives general fitness information and guidance only. Always consult a doctor before starting a new fitness program, especially if you have health concerns.
