The part calories do not explain.
Sodium, potassium, calcium, iron, magnesium, zinc, phosphorus and the vitamins. Derived from the food you already logged, with nothing extra to enter. It is usually what explains why a week felt worse than the calorie total suggested it should.
Free · Derived automatically from your food log

You already did the work.
Every micronutrient here comes out of food you logged for other reasons. There is no second screen to fill in and no supplement diary to keep.
Fifteen, derived from what you ate
Sodium, potassium, calcium, iron, magnesium, zinc and phosphorus, plus the vitamins, alongside fiber and the headline macros. All of it is computed from entries already in your log, you do not enter any of it separately, and adding a meal fills in its micronutrients at the same time.
Free- Sodium, potassium, calcium, iron, magnesium, zinc, phosphorus
- The vitamins, plus fiber alongside the headline macros
- Derived from your existing food log, not a second chore
- Daily and rolling views, with gaps called out rather than hidden

It tells you when it does not know
A micronutrient figure is only as good as the entry it came from, and not every food in any database carries a full panel. Where Loopa is working from an estimate it labels it as one and shows its working; where the data is too thin to say anything useful, it says that instead of drawing a confident line through nothing.
Free, 5 estimates/day- Estimates labeled as estimates, with the working shown
- Gaps called out rather than quietly averaged over
- Correct any value in a tap
- Free tier gives you up to 5 fresh estimates a day
Alongside everything else you track
The point of having micronutrients here is that they sit next to the rest of your day rather than in a separate app. The same log that fills in your macros fills in your sodium and iron, and it sits beside your weight trend, your water, your blood pressure and glucose, your fasting window and your meal plan, one account, one subscription, one place to look.
Free- Beside your weight trend, water, activity and vitals on the same screen
- Feeding the meal planner, so a plan is built against your targets
- Included in the monthly report in plain English, not just a chart
- Free for every member, on iPhone and Android alike
More on how Loopa works
Questions people ask
How many micronutrients does Loopa track?
Fifteen: sodium, potassium, calcium, iron, magnesium, zinc and phosphorus, plus the vitamins, alongside fiber and the headline macros. All fifteen are derived from food already in your log rather than entered separately.
Do I have to log micronutrients separately?
No, and that is the point of it. Every figure is computed from entries you made for other reasons. Logging lunch fills in lunch's micronutrients at the same time. There is no second screen and no supplement diary to keep up.
Is micronutrient tracking free?
Yes, free. They are derived from food you had already logged, so charging for them would be charging you to read your own entries back. Fifteen of them, against the Recommended Dietary Allowance for your age and sex, the figures the Institute of Medicine publishes in its Dietary Reference Intake tables, with the estimator that fills in what a food label leaves out, also free, with an allowance of 5 fresh estimates a day, because without it the screen is a column of blanks.
Which micronutrients does Loopa track?
Sodium, potassium, calcium, iron, magnesium, zinc and phosphorus, plus the vitamins, alongside fiber and the headline macros. Fifteen in all. They are the ones that most often explain how a week actually felt, and every one of them is filled in from food you already logged.
Why track micronutrients in the same app as everything else?
Because that is where they are useful. Your sodium sitting next to your blood pressure, your iron next to how the week felt, free, on the same account. Add Premium and the same nutrient picture also feeds the meal planner that builds your next few days. That is what you get from one app rather than several, and Loopa Premium Family covers up to six people for $119.99 a year.
What happens when the data is incomplete?
Loopa says so. Where a value is estimated rather than read from a nutrition panel it is labeled as an estimate with its working shown, and where the data is too thin to draw a conclusion it says that instead of showing a confident line through nothing. You can correct any value in a tap.
