Features → Coach Mo
The AI fitness coach that remembers you.
Coach Mo is MoveTogether's AI coach: five personalities, long-term memory, awareness of your activity and competitions, and a privacy design that redacts your identity before a message leaves the app. On iPhone, tap + and choose Ask Coach Mo.
This is what a chat with Mo looks like.
Ask in your own words. Mo checks your rings, your last few days and your goals, then answers in the voice you picked.
Without Pro you get 5 Coach Mo messages, once. Pro is unlimited, and lists what Mo checked above each reply.
What makes Mo different
Most "AI fitness coach" apps wrap a generic chatbot in a workout-branded UI. It forgets you between sessions, never sees your activity, and gives everyone the same answer.
Coach Mo starts from your data: your activity, competition history, and goals, and it remembers everything you tell it through a system called Files. Ask "how should I pace today?" and Mo looks at your week, your goal, and the patterns it has learned about you.
And it does it under a privacy architecture where your name is never sent to Anthropic: it's redacted to a placeholder and restored on your device.
Five personalities. Pick the one you want to hear from.
The same facts land differently depending on who says them. Switch voices whenever your mood changes.
Classic Mo
Gen Z energy, zero filter
How am I tracking on my rings this week?
Classic Mo
The everyday voice. Encouraging when you're winning, honest when you're not. The persona Coach Mo starts you on.
Drill Sergeant
No excuses, soldier
How am I tracking on my rings this week?
Drill Sergeant
For when you need a push. Cuts through your reasons and reminds you what you said you were going to do.
Hype Man
Your biggest fan
How am I tracking on my rings this week?
Hype Man
For when the win matters more than the analysis. Loud, joyful, all-caps energy when you close a ring.
Big Sibling
Caring, honest, always real
How am I tracking on my rings this week?
Big Sibling
For when you're being hard on yourself. Reminds you it's a long game and that off days aren't failures.
Sports Analyst
The numbers don’t lie

Sports Analyst
For competition mode. Talks pace, splits, and trends; helps you read the leaderboard like a coach reads tape.
Coach Mo, all five personalities, and Roast Mode are part of Pro.
Files: long-term memory you control.
Coach Mo remembers you as plain-English notes in seven folders, not hidden embeddings. You can see, edit, and delete every entry.
User
Basic facts you share: age, location, the demographics you choose to tell Mo about.
Goals
"Close my Move ring 6 days a week" or "Run a sub-50 10K by July."
Habits
"Walks the dog every morning before 7am." Patterns Mo notices and stores.
Barriers
"Hates Mondays" or "Travels for work two weeks a month." What gets in the way.
Preferences
Favorite workout times, foods to avoid, exercise types you love and hate.
Wins
Personal records, streaks, milestones. The reference points Mo brings back up.
Roast material
"Said she'd run 5K on Sunday. Did 847 steps." Mo's ammunition for Roast Mode.
Your name never leaves the app.
Before any message goes from MoveTogether to Anthropic, the model provider behind Coach Mo, your name, your friends' names, your email, and your username are redacted to placeholders. The model never sees them.
When the response comes back, your names are restored on your device.
It is built in, not a setting, and it applies to every Coach Mo message.
Coach Mo also shows you an activity trace under each response: exactly which pieces of your data Mo used to answer you.
Roast Mode: when you want a wake-up call instead of a pep talk.
Flip Roast Mode on and Coach Mo turns sarcastic. Your own numbers are the setup for the joke. Roast Mode is part of Pro.
“Hey, light day yesterday. Want to talk about what got in the way?”
“Not you sitting at 847 steps like that’s a flex. My grandma’s Fitbit is judging you right now.”
The Weekly Mo Report: your Monday recap of your training week.
Every Monday morning, Coach Mo builds a slide-style recap of your week: activity highlights, competition results, streak progress, and where to push.
The voice of the report adapts to your chosen persona. A Drill Sergeant report reads nothing like a Hype Man report. Pair it with Roast Mode and you get the Weekly Roast Card: a fun, irreverent summary you can share to your phone’s native share sheet or straight to friends.
Weekly Mo Reports and Roast Cards are Pro features.
Saturday’s 9,460 steps carried a week that sagged midweek.
Wednesday and Saturday both cleared 8,000 steps. Give Thursday’s 4,180 the same treatment and next week averages close to 7,000.
Sunday’s 3,870 steps were one lap of the couch. Thursday’s 4,180 says you walked to the fridge and called it cardio.
“Saturday showed what you’ve got. Bring it Monday.”
What Coach Mo can and can’t do.
Coach Mo can
- Hold a real conversation about your goals, motivation, your activity, or just venting after a rough week.
- Remember what you told it weeks ago and bring it back up at the right moment.
- Surface insights when you're viewing a competition, your activity rings, or an achievement.
- Generate a personalized Weekly Mo Report every Monday in your chosen persona's voice.
- Switch into Roast Mode when you want sharp humor instead of encouragement.
- Suggest a temporary plan for travel, illness, or a busy week, and ease off reminders once you confirm.
- Talk back via voice: spoken conversation, with the same memory and personality.
Coach Mo cannot
- Create competitions, change settings, or send messages for you.
- Write structured strength programs with sets, reps, and progressions. That's a different tool.
- Diagnose conditions, prescribe treatments, or replace a real doctor or certified trainer.
- See data you haven't shared. Mo knows your Files and the activity MoveTogether can see.
- See your friends' separate Coach Mo conversations or modify anyone else's experience.
