Nutrition tracking for iPhone
Nutrition beyond calories
Most apps count calories. Log Nutrients helps you understand what you eat — tracking calories, protein, sodium, potassium, and your sodium-to-potassium ratio, with trends that show where your health is heading.
Track what actually matters
The problem
Calories tell only part of the story
It's easy to track what every app already shows you — and easy to miss the nutrients that quietly shape how you feel.
What most apps track
Calories
Protein
Carbs
Fat
What they leave out
Sodium
Potassium
The balance between them
One simple log
Every nutrient that matters, in one place
Log a meal once and Log Nutrients captures calories, protein, carbs, fat, sodium, and potassium together. Save your go-to meals and add them again in a single tap.

The feature most apps skip
Your electrolyte balance, made simple
Sodium and potassium work together, yet most apps show them in isolation. Log Nutrients brings them into one clear electrolyte balance — so you can understand their relationship, not just track two separate totals.

The long view
See the trend, not just today
Single days bounce around and tell you very little. Two-week and one-month trends reveal where your nutrition is genuinely heading — calories, deficit, sodium, potassium, and protein over time. Log Nutrients Pro extends that view to three months and a full year.

Why balance matters
High sodium gets the headlines. Low potassium gets ignored.
Almost everyone hears that sodium can run high. Far fewer hear that potassium often runs low. The balance between the two can matter as much as either number on its own — which is exactly what the sodium-to-potassium ratio captures.
Sodium
Widely discussed and easy to overdo, especially in packaged and restaurant food.
Potassium
Found in whole foods like vegetables, fruit, and legumes — and easy to fall short on.
The ratio
Seeing them together gives a fuller picture than tracking either number alone.
Log Nutrients is a tracking tool, not medical advice. For guidance about your own diet, talk with a qualified professional.
Built from a real need
Because nothing else made this easy
Log Nutrients started with a simple frustration: existing apps made it hard to see sodium, potassium, and long-term nutritional trends in one place. Rather than competing feature-for-feature, it solves that one problem well — accurate logging, the nutrients that get overlooked, and a clear view of how things change over time.
