Food and calorie tracker
Tell your assistant what you ate. Fettle keeps the log.
Say “two rotis and a bowl of dal” to Claude and it lands in your log with calories and macros, ready to review on your phone. No searching a food database, no typing.
- Works with Claude
- Android, iPhone planned
- No ads, no data sales
Why Fettle
A calorie counter that fits how you actually eat
Home-cooked meals, shared plates and “a bit of everything” are hard to log in a database. Describing them is easy.
Talk, don’t type
Describe a meal in your own words. Your assistant splits it into items, estimates calories and macros, and files it under the right meal.
See the whole picture
A daily ring, protein, carbs and fat, a weekly chart, a logging streak and your weight trend, all in one calm view.
Eaten, burned, net
On Android, Fettle reads active calories from Health Connect, including from Samsung Health, and shows your net for the day.

FAQ
Questions
Do I have to type every meal?
No. Tell Claude what you ate, like “two rotis and a bowl of moong dal for lunch”, and it adds the items to your log with estimated calories and macros. You can edit or delete anything in the app.
How accurate are the calories?
They are estimates. Your assistant works out calories and macros from what you describe, so the numbers are only as exact as the description. Every entry can be edited in the app if you know better.
Which assistants does it work with?
Fettle connects through the open MCP connector standard. Claude is supported today. Other assistants that can add a custom connector may work with the same link, but only Claude has been tested.
Does it work on iPhone?
Fettle is built for Android first. An iPhone version is planned.
Can I disconnect my assistant?
Yes, any time. The Settings screen shows when your assistant last used Fettle, and Disconnect stops it immediately.
