Tap the ring to see each item, its weight, and what would raise the day most.
Pace comes from a line fitted over four weeks, with a likely range and a cone, not a guess from two weigh-ins.
Health values are encrypted with a key per person before they reach the database. No ads, and no selling of data.
Every change an assistant makes is in your activity log, and one tap puts it back.
Paste one prompt into your assistant. It asks a few questions, finds your activities, and fills in your profile through the revns connector. You approve the sign-in once.

Set up my revns profile. revns is a fitness, health and wellness tracker with an MCP server. 1. Connect to the MCP server: https://mcp.revns.com/mcp (Streamable HTTP, OAuth). I will approve the sign-in. 2. Call list_metrics to see what exists. Keep it. 3. Ask me, in one message, at most five short questions: my objective (lose_fat, build_muscle, endurance, general_health, mobility, mental_wellbeing or event), what activities I do, my weight (kg) and height (cm), how I eat, and anything else I want to track (sleep, mood, gut health, periods and cycle, VO2 max). 4. For each activity, call find_activities with a short query and use the keys it returns. 5. Call set_profile once with everything. Call set_goal if I name a target. 6. Reply with a short summary of what you set up. Rules: training and tracking guidance only, never medical advice. Offer private tracking (sex, masturbation, libido, periods) once, as opt-in. Do not log entries during setup. Skill with the same steps: https://revns.com/skills/revns/SKILL.md
The week planner
It reads your sleep, recovery, last week's load, your strength rotation and what is due, then lays out seven days: which session goes where, how hard each day is, one rest day, and what to eat for protein that fits your diet.
Bring your own AI
Connect any MCP client. It reads your day and your trends, and with your permission logs entries and meals, sets goals and plans your days. Every change uses the same checks as the app and is labelled with the assistant's name.
Train together
Invite by email or share a join code. Nothing is shared until the other person joins. A team shares the sessions and exercises it tracks, day scores and streaks, never sleep, meals, mood, notes or goals, and anyone can leave at any time.
Logging, the score, the plan and one AI assistant stay free for good. Everything is free until at least Monday, Dec 14, 2026.
revns is a fitness tracker and AI coaching layer. You track any discipline (strength, running, yoga, swimming, combat sports, sleep, meals, habits) as metrics with your own targets. revns turns them into one daily score and a morning brief, and exposes everything to Claude, ChatGPT and other assistants through an MCP server so they can log, plan and coach for you.
Add the revns MCP server (https://mcp.revns.com/mcp) as a custom connector in Claude or ChatGPT, sign in, and approve the permissions. The assistant can then read your day, trends and goals, and, if you allow it, log entries, log meals, set goals and plan your days.
Type one line such as "40 squats, slept 7h, ran 5k, lunch dal rice 25g protein" and revns logs every part of it. Meals take two taps: a few words, then On plan or Off plan. Every metric also has a one-tap tile.
Yes. Create a team (a couple, gym buddies, a crew, a club, or a coach with clients) and invite people by email or share a join code. Nothing is shared until they join. A team shares only the sessions and exercises it tracks, day scores and streaks, never sleep, food, mood, body, notes or goals, and anyone can leave at any time.
Yes. Export your tracking sheet as CSV with a Date column. Columns revns recognises map to library metrics; any other column becomes a custom metric, with its kind and target inferred from your data. Computed columns such as scores and averages are skipped.
No. revns gives training guidance only. It does not diagnose or treat any condition and does not recommend drugs or supplements. See a clinician for symptoms such as chest pain, fainting or an injury.
Pick an objective, tell it how you eat, log one thing.
