Photograph a meal, see its seed oil.

Common questions

How accurate is the estimate?

It is an estimate, which is why it is shown as a range with a stated confidence rather than a single number. Trace reads how a dish was cooked, how large it is, how greasy it looks and how much dressing or sauce is on it, then computes from published oil absorption rates. The biggest unknown is which oil a kitchen actually used — so when Trace has to assume, it says "assumed", and you can correct it in one tap.

How does it know which oil was used?

It doesn't, and it doesn't pretend to — the oil is not visible in a photograph. Trace infers a likely oil from the kind of venue and cuisine, and for meals you cook at home it uses the oil you told it you cook with. Tap "Cooked in" on any result to set it yourself; the number updates instantly.

Why did my salad score higher than my steak?

Almost always the dressing. Two tablespoons of a standard restaurant dressing is around 14g of oil on its own — more than many sautéed main courses. A steak cooked in butter or tallow contains no seed oil at all.

How do I change my daily target?

Settings → Daily target.

How do I cancel my subscription?

Subscriptions are billed by Apple, so they are cancelled in Apple's settings: open the Settings app, tap your name, then Subscriptions, then Trace. Cancelling stops the next renewal; you keep access until the period you have paid for ends.

I paid but the app still says I'm on the free tier.

Tap Restore at the top of the subscription screen. If it still doesn't appear, email us — we can see whether the receipt reached us and fix it.

How do I delete my account?

Settings → Delete account. It removes your profile, every meal, every photograph and the account itself, immediately and permanently.

Where are my photos stored?

In private storage, readable only by your account. Location data is stripped from every photo on your device before it is uploaded. Full detail is in the privacy policy.

Is seed oil actually bad for me?

We try to be straight about this. No health authority sets a limit on seed oil intake, and linoleic acid — the main fat in most seed oils — is essential in the diet. The most defensible concern is about repeatedly reheated frying oil, which is common in commercial kitchens. Trace tracks a dietary preference and shows you where yours is coming from. It is not medical advice.
