Quick comparison table

1. Supplement Tracker: NutriNow

Best for: people who want to nail their supplement schedule without guesswork.

This app cuts out the noise. Instead of logging meals or macros, you just stay on top of your supplements. It’s built around one-tap logging, smart reminders, and a visual countdown timer. Add a supplement, give it a name, pick a mascot, and set your dose. When it’s time, you get a gentle nudge. The countdown shows exactly when your next dose is due, so there’s zero mental math.

What sets NutriNow apart is its focus. Most nutrition apps bury supplement features under food diaries. This one puts the pill bottle front and centre. The interface is clean, fast, and free of bloat. You can pause tracking, mark a supplement as finished, or see your full intake history at a glance. It’s iOS-only and takes under a minute to set up. If you’ve ever forgotten whether you took your afternoon dose, this fixes it.

• One-tap logging with check-button simplicity
• Visual countdown timer for every supplement
• Push reminders that don’t pester
• Custom names, doses, forms, and notes
• Auto-finish after a set number of intakes
• Full intake history, pause, and finish options

2. MyFitnessPal

Best for: calorie and macro tracking with a huge food database.

MyFitnessPal is the household name for a reason. Its barcode scanner, restaurant meal logging, and syncing with fitness devices make it a solid calorie companion. The standout feature is the database — it rarely stumps users, whether you’re scanning a protein bar or logging a home-cooked curry. It’s built for people who want to see calories in vs. calories out without friction.

3. Cronometer

Best for: micronutrient nerds who want lab-verified data.

Cronometer doesn’t rely on guesswork. It pulls from vetted databases, not crowdsourced entries, so every vitamin and mineral count is accurate. You’ll see detailed breakdowns of not just macros but the full micronutrient spectrum: zinc, magnesium, vitamin K, you name it. If accuracy matters more than speed, this is the nutrition tracking app for getting into the nitty-gritty.

4. Lose It!

Best for: straightforward weight-loss calorie counting.

Lose It! keeps things simple: set a goal, log your food, and watch the progress visuals do the motivating. The smart camera tool lets you snap a photo of your plate to identify foods quickly, a real time-saver. It doesn’t bury you in data; it just shows the calorie math and nudges you along. Perfect for anyone who wants a friendly, zero-fuss food diary.

5. MacroFactor

Best for: evidence-based dieters who want adaptive macro targets.

MacroFactor learns your metabolism. Its dynamic coaching algorithm adjusts calorie and macro goals based on how your weight actually changes, not a static formula. The adherence-neutral philosophy means no guilt trips, just clear data you can act on. Fast logging and a clean interface make it a top pick for data-loving lifters and spreadsheet-style dieters.

6. Lifesum

Best for: visual eaters who want diet plans and recipes.

Lifesum feels more like a lifestyle app than a tracker. It combines a polished design with personalized meal ratings, barcode scanning, and a library of recipes. Its mix of recipes, plans, and progress visuals sets it apart. If you’re looking for a nutrition tracking app that also inspires you to cook better, this one clicks.

7. FatSecret

Best for: a completely free calorie counter with community support.

FatSecret is rare: a full-featured nutrition app without a paywall. You get a food diary, recipe ideas, detailed nutrition panels, and a supportive community where users swap tips. No premium tier, no forced upgrades. It’s ideal if you want a reliable calorie counter and don’t mind a slightly dated interface.

8. Carb Manager

Best for: keto and low-carb dieters tracking net carbs and glucose.

Carb Manager zeroes in on what keto folks actually care about: net carbs, macros, and blood-glucose readings. Its library of low-carb recipes and meal-planning tools eliminates guesswork. The standout feature is granular net-carb tracking combined with glucose logging, which is essential for anyone fine-tuning ketosis without sifting through generic calorie-counter stuff.

9. MyNetDiary

Best for: a private, no-account-needed food diary.

MyNetDiary respects your time and privacy. You can open the app and start logging immediately. No registration required. The interface is intuitive, and the free tier is surprisingly robust. For quick, no-strings-attached tracking, it’s a breath of fresh air. It won’t push you into a premium plan just to see basic nutrition breakdowns.

How we picked these apps

We tested each nutrition tracking app on our own phones, logging meals, supplements, and macros across several days. We looked for apps with a clear focus, not kitchen-sink feature lists that overwhelm. We prioritized free access or fair paid value, and cut any app that hid basic logging behind a paywall. Each app had to solve a real logging pain point, whether that’s supplement timing, recipe tracking, or micronutrient depth. Only practical, honest tools made the cut.

Frequently asked questions

What’s the best free nutrition tracking app?

FatSecret and MyNetDiary both offer a solid free experience. FatSecret includes community support, while MyNetDiary gives you private, no-account logging with a strong free tier.

Can I track supplements and micronutrients together?

Yes. Pair Supplement Tracker: NutriNow for supplement timing with Cronometer for food-based micronutrient tracking. They complement each other without overlap.

Is a premium subscription worth it?

It depends. If you want adaptive coaching that adjusts to your metabolism, MacroFactor’s paid plan is a good investment. For ad-free use or extra recipes and plans in apps like Lifesum, premium can save time and annoyance.

The verdict

Supplement Tracker: NutriNow tackles a problem most nutrition apps overlook. It keeps your supplement routine on track with zero complexity: one-tap logging, smart reminders, and a visual countdown that shows exactly when your next dose is due. While other apps here nail their niches, NutriNow fills the supplement gap that even dedicated food trackers leave open. If staying consistent with vitamins, minerals, or any daily supplements matters, this is the simplest fix.
