See what you ate, what you have left, and how your week is balancing—without digging through a giant food database or doing math in your head.
Protein first. Flexible fats and net carbs. Your foods, your real meals.
The whole app comes back to two questions
Three Macros keeps both answers visible, so your next meal does not require another calculation.
My Pantry
Foods I actually eat
Build your own pantry
No giant food list.No guessing.
Most nutrition apps hand you thousands of foods you’ll never eat. Three Macros starts differently. Save the foods you actually buy and build a Pantry that becomes faster every time you use it.
Your foodsSave the foods you actually buy. No scrolling through thousands of unrelated results every time you eat.
Your mealsSave breakfasts, dinners, restaurant orders, and combinations you repeat so logging gets faster over time.
Built around youYour Pantry starts empty on purpose. It grows with your habits—not someone else’s.
Get started
One file. Yours forever.
Buy once. Use it on your personal devices. Your data stays locally on each device.
Secure Stripe checkout will be connected before launch.
Good to know
Simple on purpose.
Three Macros is one standalone file. Download it once, open it in your browser, and start with the foods you actually eat.
Three steps. That’s it.
No login. No password. No subscription.
Is this a spreadsheet?
No. Three Macros is a real interactive HTML file. There are no cells to break and no formulas for you to accidentally delete. Open it in your browser and it behaves like an app.
Do I need an account?
No account, login, or password is required for the standalone version. Open the file and it is ready to use.
Can I use Three Macros on my phone?
Yes. Three Macros works in supported desktop and mobile browsers, and the interface automatically adapts to the screen size.
Will my phone and computer sync?
Not yet. Three Macros stores your information locally on the device and browser you use, so your phone and computer will each have their own data.
We’re planning a future cloud version with optional syncing between devices.
Want that feature? Join the list and we’ll let you know when it’s ready.
Can I use the same purchase on more than one personal device?
Yes. The personal-use license allows the purchaser to use their copy on their own devices, but saved data does not synchronize between them.
Where is my information stored?
Foods, meals, goals, and history remain locally in the browser. Three Macros does not upload nutrition data to an account or cloud database.
What happens if I clear my browser data?
Clearing browser or site data may erase saved information. Private browsing is not recommended.
How do I open it on my phone?
Download the HTML file, open it in a supported browser, and follow the included setup instructions. Where supported, it may also be added to the Home Screen.
Do I need to download it again for another device?
Customers may transfer or download their purchased file onto their own additional devices. Each device stores separate data.
What exactly will I receive?
The standalone Three Macros HTML application, setup guide, version information, and personal-use license.
Does it work offline?
Yes. The core tracker works without Wi-Fi or internet. Your information stays in that browser on your device. Speech recognition and website links may still require browser support or internet access.
Is this medical advice?
No. Three Macros is a tracking and educational tool, not medical or nutrition advice. Always check with a qualified clinician for guidance specific to you.
Can I share the file?
No. Your purchase is licensed for personal use. The application may not be shared, distributed, copied for others, or resold.
Will I receive future updates?
Early customers who join the Three Macros update list will receive product news and launch offers as the project grows toward a hosted app. The planned early-customer offer is separate from the standalone file purchase and will be explained before signup.
What’s next
Want Three Macros on every device?
A future cloud version may include backups, cross-device sync, updated food data, and new tools—while keeping the same no-nonsense approach. Join the early update list for product news and future launch offers.
