Build Your Own Net-Carb & Macro Tracker for Keto

If you’re on keto, you don’t need net carbs, protein, and fat the way most macro apps assume. The good news: instead of hunting for the perfect app, you can build your own keto macro tracker in Auto that counts exactly what you care about.

Why build instead of download

Search “macro tracker for keto diet” and you’ll find plenty of options. Some are good. But most generic trackers bury net carbs, push a huge food database you didn’t ask for, or lock keto-specific features behind a subscription. If you’ve been looking for a keto net carb tracker app or a carb manager alternative, the honest answer is that any off-the-shelf app is someone else’s idea of how you should eat.

Auto flips that. You describe what you want, snap a photo of your meal, and Auto builds you a personal mini-app—a “Frame”—around your exact targets. It takes minutes, and it fits because you defined it.

Building it in Auto

Here’s the short version of how to track macros on keto with your own Frame:

  1. Tell Auto what to track. Say you want to log meals by photo and text, and pull calories, protein, fat, and carbs from each—plus fiber and sugar so you can watch net carbs.
  2. Describe your screens: today’s meals with daily progress, a history view, trends over 7 and 30 days, and a settings screen for your targets.
  3. Set your keto targets—low carbs, higher fat, protein to goal.
  4. Snap a photo of a meal. Auto estimates the macros. Adjust anything that’s off.

That’s a working tracker. From there you shape it.

How someone built theirs

One Auto user built a Frame they simply called “Meal Tracker,” and their prompts show how it grew.

They started broad: analyze food photos, extract primary stats (calories, protein, fat, carbs) and secondary ones (fiber, sugar, sodium), then lay out four screens—today, history you can swipe day to day, trends with bar charts, and settings for targets.

Then they refined. They added manual meal entry by typing or just telling Auto what they ate. They wired up meal-time push reminders. They made each meal open a full detail page with a full-bleed photo, then asked for bigger, chunkier stat numbers and icons for each macro so it looked less plain.

They also fixed real problems as they hit them—meals landing on the wrong day until timezones were handled correctly, and delete buttons and content hiding behind the tab bar until padding was fixed. They even let Auto’s chat read and edit their food items, settings, and goals directly.

The point: they didn’t settle. Each tweak made it more theirs.

FAQ

Can it track net carbs specifically? Yes. Ask Auto to pull carbs and fiber per meal and show net carbs. Keto is about net carbs, so build that in from the start.

How accurate are photo estimates? They’re solid estimates, not lab measurements. You can edit any meal, or add it by text when a photo won’t do.

Do I need to code? No. You describe changes in plain language and Auto builds them.

Can I change it later? Yes—it’s your Frame. Add screens, notifications, or new stats whenever your goals shift.
