Blank Fit Get Blank Fit
Calorie and training tracker · iPhone, Apple Watch, and your AI assistant

Say what you ate.
Consider it logged.

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.

Free to log, with no entry limit. Connecting an assistant takes about a minute.

AI assistants · Model Context Protocol

Works inside the assistant you already use.

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.

01
Copy one address

mcp.blankfit.app is the only technical thing you will ever see, and the app copies it for you.

02
Paste it into your assistant

Every assistant has a place for custom connectors. Pick yours in the app and it shows the exact taps.

03
Sign in and tap Allow

You decide what the assistant may read and whether it may log for you. Disconnect in one tap, any time.

Things to say

Ask it anything the log can answer.

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.

What did I average for protein last week?
Log the pastry from the station, about 300 calories, as a snack.
How much is left today if I have the pasta tonight?
Move the croissant to breakfast. I put it in the wrong meal.
Save last night’s dinner as a recipe called Tuesday salmon.
Plan a forty minute push day for Thursday, no barbell.
Was the deficit real this week, or did the weekend cancel it?
Swap bench for dumbbell press in tonight’s session.
What did I eat on the days I hit my protein target?
Add 250 ml of milk to breakfast.

The app

When you would rather tap.

Every job gets one screen, every action can be undone, and nothing stands between you and a logged meal.

Quick add

Calories are the only required field. Choose a preset, tap Add, and you are done in two taps.
