Frequently asked questions

Everything you need to know before you start tracking.

How does the AI photo calorie counter work?

Take a photo of your meal and MacroLens uses AI to recognize the food and estimate its calories, protein, carbs and fat in seconds. You can also scan a barcode, search the food database, or describe your meal in text.

What is multi-angle precision scanning?

After your first photo you can capture the same meal from two or three angles. Using parallax and volume estimation, this can reduce portion-size error by roughly 40% compared with a single photo — it’s what makes MacroLens more accurate than a quick snap.

Is MacroLens free?

Yes. MacroLens is free to download and you can explore it as a guest. An optional Pro subscription unlocks unlimited AI scans and advanced tracking.

How accurate are the calorie and macro estimates?

Estimates are approximations meant to guide you, not medical advice. You can edit any result before saving, and multi-angle precision mode improves portion accuracy. For conditions like diabetes or allergies, please rely on a professional.

Which sign-in options are supported?

Email and password, Google, and Apple (including Hide My Email). You can also try the app as a guest without an account.
