Logging is where most food trackers lose people

Searching a database, picking the right entry and guessing grams for every item gets old fast. A photo takes seconds, so you're far more likely to keep going long enough to learn something useful about your diet.

✓No searching item by item
✓No scales or measuring cups
✓Works for home cooking, eating out and takeaways
✓Upload photos later if you forgot to log at the time

How it works

1

Take or upload a photo

Point your camera at your plate, or pick a photo from your camera roll.

2

Boone does the work

It identifies what's on the plate and estimates each portion from the image.

3

Check and save

Add a detail if you want to, such as veggie rather than beef, then save it to your day.

One photo, the full picture

Every meal you snap is broken down the same way as everything else in Boone, based on your age and sex.

Add a detail when it matters

A photo can't always tell beef mince from soya, or whole milk from skimmed. When the difference matters, tell Boone in a tap and your numbers update. When it doesn't, just save and move on.

Good estimates, not lab measurements

Photo logging estimates what's on your plate and how much of it there is. It's quick and close enough to show real patterns in your diet, which is what matters over weeks and months. Mixed dishes and food made to order are the hardest to judge, so that's where adding a detail helps most.

Not every meal needs a photo

Type it

Write it the way you'd say it: "two slices of toast with butter and a flat white".

Optional

Add your DNA for extra context

An optional home test adds your nutrigenetic profile, covering areas such as vitamin metabolism, iron and omega-3. It doesn't change your targets. It adds weight to the advice Boone already gives, where your genetics point the same way.

Questions about photo food logging

How it works, how to get the best results, and what happens to your photos.

What is photo food logging?

A way to record what you eat by taking a picture instead of searching for each item. Boone identifies the food in the photo, estimates the portion sizes and adds the nutrition to your day.

How does Boone recognise food from a photo?

Boone uses image recognition to identify the foods on your plate, then estimates how much of each there is from the image. Each item is matched to nutrition data and broken down the same way as everything else you log.

Can I upload a photo I took earlier?

Yes. You can take a photo in the app or upload one from your camera roll, so it still works if you forgot to log at the time.

Does it work for home cooking, restaurants and takeaways?

Yes. Photo logging works for anything on a plate. For restaurant and takeaway food, where recipes and ingredients are not published, the breakdown is an estimate based on what the dish usually contains.

Should I use a photo for packaged food?

For packaged food, scanning the barcode is usually quicker and more precise, because Boone can use the product's own nutrition information and ingredient list. Photos are best for meals on a plate.

How do I get the best results from a photo?

Get the whole plate in frame, in reasonable light, from slightly above. Try to keep separate foods visible rather than stacked. If something is hidden, such as a sauce, dressing or the oil it was cooked in, add it as a detail.

Does it work for mixed dishes like curry, stew or pasta bake?

Yes, although mixed dishes are the hardest to judge from a photo because ingredients are combined. Boone will estimate the dish, and adding a detail, such as vegetarian rather than beef, makes the breakdown much closer.

What about drinks?

You can log drinks by photo, but for things like coffee it is often quicker to type it, for example "large flat white with oat milk", since milk type and size are hard to see in a photo.

Can an app really count calories from a photo?

It can give you a good estimate, not a lab measurement. That is close enough to show real patterns in your diet over weeks and months, which is what makes tracking useful. When you want more precision, you can correct items and portions in a tap.

How does Boone estimate portion sizes?

From the image itself, so you do not need to weigh anything. If a portion looks wrong, you can adjust it before saving.

What if Boone gets something wrong?

Edit it. You can change an item, adjust a portion or add a detail, and your totals update straight away.

Is photo logging getting better?

Yes. We are improving recognition all the time, particularly for mixed dishes and food eaten out.

What does Boone show me after I log a photo?

Calories for the meal and each item, macros (protein, carbohydrate and fat), 29 vitamins and minerals, and a rating for how processed the meal is likely to be. Everything is added to your daily dashboard.

Can Boone tell how processed a meal is from a photo?

It gives a prediction. A photo cannot show an ingredient list, so Boone predicts the rating from what is on the plate and your purchase history. Scanned products are rated from their full ingredient lists, so they carry more confidence.

Will a photo flag ingredients I want to avoid?

Only in a limited way. A photo cannot show hidden ingredients such as sesame in a sauce or nuts in a pesto, so do not rely on photo logging to spot them. If an ingredient matters to you, check the label or ask, especially if you have an allergy.

Is photo logging free?

Yes. Photo logging is included on the free plan, along with every other way to log: text, barcode and receipt.

Do you sell my photos or data?

No. We never sell or share your photos or personal data with advertisers or other commercial third parties. You can ask for a copy of your data or have it deleted at any time.

Is Boone medical advice?

No. Boone is not a medical device and does not diagnose or treat anything. If you have a health condition or ongoing symptoms, speak to your GP or a qualified healthcare professional.
