Build Your Own Calorie Tracker Instead of an App
If you want to track calories and macros the way you eat — not the way some generic app assumes you do — you don’t have to settle for a download. With Auto, you describe the tracker you want, and it builds you a personal mini-app (a “Frame”) around it in minutes.
Why build instead of download
There are plenty of calorie apps out there, and some are genuinely good. But most bury the features you actually use behind subscriptions, ask you to log in ten ways, and still don’t quite fit your routine. If you’re tired of paying for calorie tracking apps — or you just want to track macros without an app that nags you to upgrade — building your own is a real option now.
The point isn’t to copy an existing app. It’s to make one that matches your targets, your meals, and the exact stats you care about. You own it, and you can change it any time by just asking.
Build it in Auto
Open Auto, describe your tracker, and snap a photo of a meal to see it work. A few things worth telling it up front:
- What to track. Calories, protein, fat, carbs — plus secondaries like fiber, sugar, and sodium if you want them.
- Your screens. A “today” view with progress toward your goals, a history you can page through by day, trends over 7 and 30 days, and a settings screen for your targets.
- How you log. Photo, free text, or just telling Auto what you ate. You can mix all three.
Because you’re describing it in plain language, you can track calories without an app-store search and without learning anyone’s menu system. If a screen looks off, you say so and it changes.
How someone built theirs
One Auto user built a Frame they called Meal Tracker, and their prompts are a good template. They started broad: analyze food photos, estimate macros from the image, and lay out four screens — today’s meals with daily progress, a swipeable history, 7- and 30-day trend charts, and a settings screen for targets.
From there they refined it the way you actually would in real life. They added manual logging by text, then meal-time push notifications. They made each meal open a full detail page with the photo full-bleed, then decided the stat numbers were too small and asked for them “big and chunky.” They fixed a time-zone bug so meals landed on the right day, added icons and a card for the calorie section to make the detail page prettier, and gave the AI chat the ability to list, edit, and update meals, goals, and settings.
They also hit ordinary polish issues — content hidden behind the tab bar, a delete button you couldn’t reach — and just described the problem until it was fixed. That’s the whole loop: describe, look, adjust.
FAQ
Do I need to know how to code? No. You describe what you want in plain English and Auto builds and updates it.
Can I log meals without taking a photo? Yes. You can add a meal by typing it or telling Auto directly — photos are optional.
Can I change my macro targets later? Yes. Set them in your Frame’s settings, or just ask Auto to update your goals.
Is this a one-time build or can I keep editing? Keep editing. It’s your Frame, so you can add screens, stats, or reminders whenever your routine changes.
