Snap your plate. Then just tell it what is wrong.
GK Health is an AI calorie counter for iPhone and iPad. Photograph your meal and it estimates the calories, protein, carbs and fat from what it recognises on the plate, and tells you what it assumed. If something is off, say so in plain words and it corrects that one item, keeping everything else.
An example
[photo of a plate: chicken, rice, broccoli]
Chicken breast (about 150 g), white rice (about 200 g cooked), broccoli and a splash of soy sauce. I assumed a medium portion of rice, so say if it was more.543 kcal · protein 55 g · carbs 63 g · fat 6 g
I think the rice was bigger, more like a full bowl
Rice changed to about 300 g. The chicken, broccoli and soy sauce are kept as they were.673 kcal · protein 58 g · carbs 92 g · fat 6 g
How it works
- Photograph the plate. Or the nutrition label on the packet, which gives the real figures instead of a guess.
- Check the estimate. It names what it sees, with the portion it assumed, and shows the calories and macros before anything is saved.
- Say what is wrong, if anything. "The sauce was teriyaki", "two slices, not one", "I think the calories are a bit higher". Speak it or type it. Only the thing you named changes.
Why talking beats tapping
Photo calorie apps usually get a plate nearly right: four things out of five. The hard part is the fifth. If fixing it means deleting the meal and starting again, or searching a database for the right sauce, most people give up and leave the wrong figure in.
GK Health keeps the conversation. It remembers what it has just estimated, so a correction is applied to that estimate, not to a fresh guess. How corrections work.
It gets better at your food
- Foods you log become your own catalogue, so the porridge you have every morning comes back with the same figures, not a new guess each time.
- Say "my usual breakfast" and it logs the version you had last.
- When you correct something, it remembers for next time.
- If a figure looks unusually big for what it saw, it says so rather than quietly logging it.
What it tracks
Calories, protein, carbohydrate, fat, fibre, sugar and salt, plus vitamins and minerals shown as a percentage of UK daily intake, with a plain-English line on what each one does. Every meal you log is written to Apple Health too.
Estimates are estimates. GK Health is a tracking tool, not medical advice. If you are pregnant, diabetic or have had an eating disorder, speak to your GP before big changes to how you eat.
Questions
How accurate is a calorie estimate from a photo?
It is an estimate. One photo cannot see the oil in the pan, the butter on the toast or what is under the sauce, so GK Health tells you what it assumed and makes correcting it a sentence rather than a form. Foods you have logged before and nutrition labels you photograph give real, repeatable figures.
Do I have to start again if it gets one item wrong?
No. Say what is wrong, for example "that is rice, not couscous", and it changes that item only. Everything else on the plate stays exactly as it was.
Can I photograph a nutrition label instead?
Yes. Photograph the label on the packet and it reads the real figures from it rather than guessing.
