Your food log is yours. VitalFill does not sell dietary data.

Can I try it before installing anything?

Yes. The nutrient tracker at drgily.com/the-calorie-counter.php runs a single day of the same calculations in your browser, with no account and nothing stored.

What does VitalFill track?

Calories plus more than 40 nutrients — protein, carbohydrate, fat, saturated fat, fibre, sugars, calcium, iron, magnesium, potassium, zinc, selenium, vitamins A, C, D, E, K, the B vitamins including B12 and folate, choline and omega-3 — each against a target set for your age, sex, and pregnancy or breastfeeding status.

Gily Ionescu, MS MD, an internal medicine physician and nutritionist with a master's degree in human nutrition. Nutrient targets come from the NIH Dietary Reference Intakes and food data from USDA FoodData Central.

Q: When is the Android version coming?

VitalFill has been submitted to Google Play and is under review. It is currently available on the App Store for iPhone.

Potassium at 66% of today's target

The idea

One picture instead of forty numbers

A table of forty nutrients is information, but it is not insight. Nobody scans forty percentages every evening and forms a view about their diet.

So VitalFill shows one nutrient at a time as a body filling with liquid. Tap potassium and you see how much of today's potassium you have covered. Tap vitamin B12 and the figure redraws. The two nutrients you should stay under rather than reach — saturated fat and total sugars — change colour as you approach the limit instead.

It takes about two seconds to understand, which is the point. A number you glance at and forget changes nothing; a picture you remember at the supermarket does.

The silhouette matches you, too — male, female, pregnant or breastfeeding — because the targets behind it differ substantially between those four, and pretending otherwise would be sloppy.

What it tracks

Everything That Actually Has a Recommended Intake

Calories and macronutrients, yes — but also the micronutrients that quietly determine how you feel and how you age.

Targets come from the NIH Dietary Reference Intakes — the RDA where one exists, the Adequate Intake where it does not, and the Tolerable Upper Intake Level as a ceiling. Food data comes from USDA FoodData Central, the same database behind most of the nutrition labels you have ever read.

Why not just count calories?

Because calories answer one question and stay silent on every other one. A day of 1,800 calories built from vegetables, beans, fish and yoghurt and a day of 1,800 calories built from refined carbohydrate are the same number and a completely different day for your body. One covers your protein, fills your potassium and calcium, and delivers the B12 your nerves and blood cells need. The other delivers energy and very little else.

A calorie counter cannot distinguish those two days. That is not a flaw in any particular app — it is what counting calories is.

	Typical calorie counter	VitalFill
Calories	Yes	Yes
Protein, carbs, fat	Yes	Yes
Vitamins and minerals	A handful, if any	40+
Targets by age and sex	Rarely	Always
Pregnancy & breastfeeding targets	Almost never	Yes
Tells you what you are missing	No	That is the whole point

I have written at greater length about why I took this route — and about the evidence that self-reported calorie counting is far less accurate than people believe — in why I built a nutrient tracker instead of another calorie counter.

Common questions

Do I need the Pro subscription?

No. The free version tracks calories, the macronutrients and a core set of vitamins and minerals, and it is genuinely useful on its own. Pro unlocks the complete nutrient set and the deeper history. Try the free version first — I would rather you decide you need Pro than be nudged into it.

Is my data private?

Your food log is yours. I am not in the business of selling dietary data, and I would not have built this if that were the business model.

When is the Android version coming?

It has been submitted and is under review. The mailing list above is where I will announce it — NutriRank, my other app, arrived on Google Play the same way.

Can I try something before installing anything?

Yes. The nutrient tracker on this site runs a single day's version of the same calculations in your browser, with no account and nothing stored. It is the honest way to see whether this approach suits you.

Who made this?

I did — Gily Ionescu, MS MD, an internal medicine physician with a master's degree in human nutrition. The nutrient targets and the food database are the ones I would defend in a clinical discussion, which is a higher bar than most nutrition apps set for themselves.
