Tools that do one thing well
Calculators, converters, generators, and templates — each one works standalone, and many combine with each other. No account required.
400 tools live so far — more added every week.
Calorie Calculator
Free calorie calculator that turns your maintenance calories (TDEE) into a daily target for losing, maintaining, or gaining weight, using the real ~7,700 calorie-per-kilogram-of-fat rule for the rate you choose.
Macro Calculator
Free macro calculator that shows carbohydrate, protein, and fat targets all at once from your TDEE — instead of the separate carb, protein, and fat calculators most sites split into three different pages.

How this site is built
No ads inside the tool
The input, the button, and the result sit in one card with nothing sold around it. Ads (where they exist) stay below the fold — never between you and your answer.
Built from real complaints
Before we build a tool, we read the app store reviews and forum threads about the ones that already exist. Each tool page links to what we found and what we changed because of it.
Runs in your browser
Most tools process everything client-side — your input never reaches a server. No file upload, no account, nothing to explain in a privacy policy beyond the basics.
Changes are logged, not hidden
Every tool page ends with an update history — what changed and when. If a tool sits untouched for a year, you can see that too.
