The Best Sodium Tracker Apps in 2026

iPhone · Free · Best for: Fastest way to track only sodium or salt

Sodio is our own app, so read this entry with that in mind. But it exists precisely because full nutrition trackers make sodium tracking slow. It does one job: log what you ate, see today’s sodium (or salt) against your daily goal, and spot trends over weeks and months.

It adapts to how your region labels food: milligrams of sodium in the US and Canada, grams of salt in the UK, EU, Australia and New Zealand, so there is no mental conversion at the shelf. There’s a home-screen widget for today’s total, and no account is required.

iPhone, Android, web · Free tier; Gold subscription · Best for: Most accurate data, and sodium-to-potassium ratio

Cronometer is the accuracy pick. Its database is built from lab-verified sources (USDA and NCCDB) rather than user submissions, and the free tier shows sodium alongside potassium, a ratio many cardiologists consider more informative than sodium alone.

The trade-off is speed: the verified database is smaller than MyFitnessPal’s, so logging takes longer, and sodium is one nutrient among dozens rather than the focus of the interface.

iPhone, Android, web · Free tier; Premium subscription · Best for: Biggest food database

MyFitnessPal has by far the largest database, over 20 million foods, and sodium appears on the free nutrient dashboard. If you eat a lot of restaurant or branded food, you’ll find it here when smaller databases come up empty.

The catch is that most entries are user-submitted, and studies have found large error rates in popular entries. For sodium specifically, stick to verified (green-check) entries or the numbers can be badly off.

iPhone, Android · Free tier; Pro subscription · Best for: Polished all-round nutrition app with sodium detail

Yazio is one of the most polished general nutrition apps, with barcode scanning free and sodium visible in the nutrient detail view. If you want meal plans, fasting timers and a modern interface alongside your sodium number, it’s a pleasant place to live.

The catch for sodium specifically: full nutrient breakdowns, including historical sodium trends, sit behind the Pro subscription, and sodium is one row among many rather than the focus.

iPhone, Android · Free tier; premium upgrade · Best for: Quickly screening packaged foods before you buy

Fooducate takes a different approach: instead of detailed nutrient logs, it scans barcodes and assigns each food a letter grade that penalizes high sodium, added sugars and heavy processing. It’s the fastest way to screen packaged foods in the supermarket aisle.

It’s a screening tool more than a tracker. The grading formula isn’t transparent, so you can’t see exactly how sodium is weighted, and you won’t get a precise running milligram total the way you do from a dedicated tracker.

Sodio is our app, so we have an obvious interest here. To keep this useful anyway: every other app on this list is one we would genuinely recommend for the use case named, we state Sodio’s real limitations (iPhone-only, sodium-only), and we link every competitor directly. We compared apps on how quickly you can log a food and see your sodium total, data quality, price, platform availability, and whether sodium is a first-class feature or a buried nutrient row.

What is the best sodium tracker app for Android?

On Android, Cronometer is the strongest choice for sodium: its free tier shows sodium and potassium from lab-verified data. MyFitnessPal and Yazio also run well on Android with sodium visible in their nutrient views. Sodio is currently iPhone-only.

What is the best free app to track sodium?

Sodio is free on iPhone with no ads and no account. Cronometer’s free tier includes sodium and potassium from lab-verified data, and MyFitnessPal shows sodium on its free dashboard, though with user-submitted data of variable accuracy.

Does Apple Health track sodium?

Apple Health can store dietary sodium as a data type, but it has no built-in way to log foods; it relies on other apps writing sodium data to it. You still need a tracking app to actually log what you eat.

What’s the difference between tracking salt and tracking sodium?

Salt is sodium chloride and is about 40% sodium by weight, so 1g of salt contains 400mg of sodium. US and Canadian labels list sodium in milligrams, while UK, EU and Australian labels list salt in grams. A good tracker should handle whichever your labels use, or you can convert with our salt-to-sodium converter.

How much sodium should I aim for per day?

The FDA and American Heart Association put the general adult ceiling at 2,300mg of sodium per day (about one teaspoon of salt), with the AHA suggesting an ideal limit of 1,500mg for most adults. The UK NHS advises no more than 6g of salt (2.4g sodium) per day. If you have a medical condition, follow the target your doctor has given you.
