How it works

Three steps, a few seconds each

  1. Snap

    Photograph your meal. Results arrive in a few seconds: the dish, calories, protein, carbs and fat, with a confidence rating.

    Scan result screen with the dish name, calories, macros and a confidence rating

  2. Adjust

    Fix a portion, swap an item or add the oil you cooked with. Every item is editable, and the app asks about easy-to-miss extras.

    Add oil or sauce sheet listing olive oil, butter, mayonnaise and other extras with their calories

  3. Adapt

    Your calorie and macro targets update from your real weight trend, and a calm daily summary shows where you landed.

Log your way

Photo, type or say it

A photo is the fastest way in. When the camera is not an option, type the meal or say it out loud, with amounts if you know them, and SnapMacro estimates it the same way.

  • Photo scan for plated meals
  • Type or dictate for everything else
  • Add a meal by hand whenever you like
Type or say it sheet with the text Grilled salmon, rice and broccoli and an Estimate button

Fix anything

Edit what the camera missed

A camera cannot see the oil in the pan. Swap a wrong item for a close alternative, change a portion, or add oil, butter or sauce in two taps. Low-confidence results say so and ask you to check them.

  • Swap items instead of starting over
  • Add oil or sauce from a short list
  • Every item, portion and dish name is editable
Scan result items for grilled salmon with rice and broccoli, each with a portion you can change

Your plan

A plan that adapts weekly

You start with a plan built from your body stats and your situation. As your weight trend comes in, the numbers are refined, so the target follows what is actually happening rather than a guess you made on day one.

  • Calories and three macro targets
  • Refined from your real weight trend
  • Optional Apple Health data sharpens the estimate

Coach

A coach that has your data

Ask how your protein is going or what to eat for the rest of the day, and the answer comes from what you have actually logged. The coach is part of SnapMacro Pro.

  • Answers based on your day and your targets
  • Quick suggestion chips when you are not sure what to ask
  • Calm daily and weekly summaries

GLP-1

Built for low appetite days

Choose the GLP-1 situation and protein comes first, the coach never shames low intake, and a short check-in records appetite, nausea and energy with a chart over time. It is the kind of detail a clinician asks about at follow-up. SnapMacro is not medical advice.

  • Protein-first targets
  • Appetite, nausea and energy check-in
  • A gentler coach

Accuracy

Photo estimates are estimates

Photo estimates are estimates; you can edit every item. Each scan shows how confident the result is, and low-confidence results ask you to check them.

A camera cannot see everything on a plate. Expect results to be useful for trends over days and weeks rather than exact to the calorie. SnapMacro is not a medical device.

FAQ

Questions, answered.

The short version of what people ask before they start. Anything else, email support@snapmacroapp.com.

How does the free trial work?

You get 7 days free. We send a reminder 2 days before the trial ends. To cancel, open Settings, tap your name, then Subscriptions, and choose SnapMacro. Cancel before the trial ends and you won't be charged. After the trial it's $59.99 per year or $4.99 per week.

What happens if I cancel?

You keep Pro until the end of the period you've already paid for. After that, Pro features pause until you subscribe again. Your logged meals stay on your phone.

How accurate is the AI?

Photo results are estimates and can be off by 10 to 20 percent or more, mostly from hidden oil, sauces and portion size. Every item is editable. Label and barcode scans are exact, because they read the numbers straight from the label. You can add a note or answer a quick question to sharpen an estimate.

Do I need a food scale?

No. Snap or describe the meal and adjust the portion if something looks off. A scale is welcome if you like one, but it's never required.

Is my data private?

There's no account to create. Your data stays on your phone, with optional iCloud backup. Meal photos are sent only to produce the estimate. Read the full privacy policy.

Does it work with GLP-1 medication?

Yes. One of the starting situations is built around reduced appetite, with protein-first tracking and a gentler coach. SnapMacro is not medical advice; talk to your prescriber about your nutrition needs.

Does it connect to Apple Health?

Optionally. If you allow it, SnapMacro reads weight, active energy and steps to refine your calorie estimate, and can write your logged nutrition to Apple Health. You choose each permission and can turn either off.

Is it a medical device?

No. SnapMacro is a tracking tool, not medical advice. The GLP-1 features are for tracking only, so talk to your prescriber about your nutrition needs.
