Why it's different
And not a chatbot that forgets you overnight. BLTBDY logs your meals and workouts right in the chat, remembers all of it, and uses that history to coach you better every day.
Your coach generates multi-day meal plans based on your macros, dietary restrictions, and preferences. Same for workouts: full training splits tailored to your schedule and goals. Edit any meal or exercise, and your coach adjusts. Tap a meal you ate and it logs to your day with the macros already filled in.
Snap a photo, scan a barcode, or just describe what you ate. Your coach figures out the food and logs calories, protein, carbs, and fat for you. No tedious manual entry.
Say what you did and your coach logs the session with the exercises and the minutes attached. It can see how often you have trained and what you have been working, so what it tells you follows what you actually do.
Your coach can look things up: how often you hit protein, where your weight is really heading, what you ate three weeks ago. The answers come out of your logs rather than out of general advice.
Some people need encouragement. Some need tough love. Pick the coaching style that actually motivates you, name your coach, and tell it how to push you.
Supportive Mentor
"Great job getting that workout in today. You're 3 days into your streak. Let's keep that momentum going tomorrow."
Savage Roaster
"You skipped legs again? That's twice this week. Your upper body called. It wants a matching lower half."
Most fitness apps wait for you to remember them. BLTBDY checks in before you fall off. Your coach nudges you when you go quiet, celebrates when you hit your targets, and remembers weeks of history: what you ate, how you trained, what worked, and what didn't.
A home screen with your streak, macros, and weight trend, your whole history a tap away, and a profile your coach actually reads.
Streak, macros, and weight trend, ready the moment you open the app.
Meals, workouts, and macro totals for any day, with your whole history a tap away.
Your targets, and a standing note of what to keep in mind. Bad knee, hotel gyms.
Steps, sleep, resting heart rate and HRV, synced from your phone, so your coach sees the whole day.

Yes. One subscription covers the iOS app and the web app, with the same account and history everywhere.
No. Generating your coach's responses means sending your profile, logs, and conversation to our AI provider, but that data is not used to train models and we never sell it. Deleting your account removes your data from our active systems and stops future AI processing; limited provider security logs may remain for up to 30 days. How your data powers your coach has the details.
Anytime. If you subscribed on iOS, cancel from your App Store subscription settings; on the web, from your billing settings. You can also delete your account entirely from Settings.
Yes. Your coach builds meal plans around your macros, allergies, and preferences, and you can edit any meal or ask for a swap.
Yes. BLTBDY is an MCP server, so you can connect Claude Code, Claude Desktop, Codex or any MCP app to your account. What you log there lands in BLTBDY and your coach sees it. You choose what a connected app can read and write, you can disconnect it any time from Settings, and it is included with your subscription. Whatever that app reads goes to the AI provider it uses, not to us.
