The nutrients your food is missing.
Photograph what you eat and Trace works out the iron, folate, B12 and twelve more that came with it — read by Apple Intelligence on the iPhone itself. One question on the front screen: how many of the fifteen did today cover?

What it does
- Reads your meal on the device One photo, one tap. Apple Intelligence names the meal, picks out the foods and works out the nutrients each one carries — on the iPhone itself. Every food arrives as a line you can correct, and fixing a portion rescales its nutrients with it.
- Fifteen nutrients, not calories Iron, calcium, magnesium, zinc, potassium, iodine, selenium, vitamins A, C, D, E, K, folate, B12 and fibre — the ones people actually run short on. Calories are shown, but they never get the ring.
- Built for a varied diet, not a smaller one There is no calorie target anywhere in Trace, deliberately. It is for people who want to know whether a diet that looks fine is quietly missing something.
- Patterns, not one odd Tuesday Every nutrient keeps a fortnight of days, the foods that actually brought it, and what to eat if the answer is "not much".
- Amounts that match you Iron is 18 mg a day against 8 mg, so Trace asks once whose day it is. Meals already saved keep the amounts they were saved under.
- Share how you are doing, never what you ate Friends you invite see how many of the fifteen you covered and how many meals it took, through your own iCloud. Not your photographs, and not which nutrients you were short of.
- Nutrients in Apple Health Turn it on and each meal is saved to Health with its calories and every nutrient Trace read, alongside everything else Health tracks.
- Six colours, and the icon follows Change the colour and the app on your Home Screen changes with it.
What it doesn't do
There is no account and no server of ours. Your photos, your meals and which nutrients you were short of stay on your iPhone, and the reading happens there too. Nothing is measured about how you use the app, because there is nothing in it that measures you. Trace is not a medical device and gives no medical advice. Read the privacy policy — it is short, because the truthful version is short.
