Blank Fit is a calorie and training tracker built AI first. Mention a meal to Claude, ChatGPT, or Gemini and it lands in the right place with the numbers filled in. The app is where you see your day, not where you type it in.
Blank Fit runs an MCP server. Add it to Claude, ChatGPT, Gemini, or any app that speaks the protocol, and your assistant can read your log and write to it with your permission. The conversation stays where it is. The numbers land in the app.
mcp.blankfit.app is the only technical thing you will ever see, and the app copies it for you.
Every assistant has a place for custom connectors. Pick yours in the app and it shows the exact taps.
You decide what the assistant may read and whether it may log for you. Disconnect in one tap, any time.
Your assistant reads the same numbers you see in the app, so its answers come from your data rather than a guess. It can act as well: log, move, swap, and plan, each change visible in the app and undoable there.
Every job gets one screen, every action can be undone, and nothing stands between you and a logged meal.
Calories are the only required field. Choose a preset, tap Add, and you are done in two taps.
A match arrives over the live camera. Unknown code? Photograph the nutrition table and the app reads it.
Log your sets and the weights move up next time. The habit heatmap records what you did and never nags.
Also on the list: an Apple Watch app that runs the workout, daily targets with the arithmetic in view, and a full export in a format other software can read.
Nothing is locked during onboarding and no paywall appears later. Pro is a row in your profile that you can visit once the app has earned it.
Free to start, nothing to configure, and your assistant is one address away.
Leave your email and we will send exactly one message: the App Store link, on launch day.
Written to be read. If a sentence here needs a lawyer to interpret it, that is our mistake.
The food and workouts you log, the figures you set as targets, and your account email. That is the whole list. There is no tracking of what you do in other apps and no advertising identifier.
Nothing until you allow it. Essential storage holds your cookie choice. If you allow analytics, we count page views and referrers without a profile attached to them.
On your device, and on our servers when you turn on sync. Sync exists so a new phone does not mean a blank history, not so we can read your meals.
Apple, for the App Store transaction and for Health data you choose to share. Our hosting provider, because the data has to sit somewhere. Nobody buys it, because it is not for sale.
The MCP server is off until you switch it on. When you connect an assistant, you choose the scope, and whatever you ask it to read is sent to that assistant under their terms, not ours. Revoking access takes one tap.
Export everything you logged at any time, in a format other software can read. No support ticket, no waiting period.
Deletion removes your log from our servers, not just your login. Backups age out within 30 days.
