1. Iron Tracker: Ferritin Counter

Best for: Replenishing iron and monitoring ferritin without the noise of full diet overhauls.

Iron Tracker zeroes in on what matters: daily iron intake. No macros, no calorie counts, no meal photos cluttering the screen. If you’re dealing with anemia, eating plant-based, or boosting iron before or during pregnancy, logging is quick and fuss-free.

• Set a daily iron target based on your gender, age, and pregnancy status (backed by NIH guidelines).
• Log from a curated list of 225 high-iron foods and see the split between heme and non-heme iron so you know what your body absorbs best.
• Add meals with a photo, barcode, or voice using AI, then review each result before saving.
• See progress at a glance with a clean ring that fills up as you get closer to your goal.
• Track your streak on a weekly calendar, earn XP, and unlock 46 achievements tied to consistent iron intake.
• Take on daily, weekly, and monthly challenges that push you to vary your iron sources.

The ferritin log quietly steals the show. Record blood test results over time and spot patterns between your eating and your ferritin. Everything runs on-device with no accounts and no data collection, so your health data stays private.

Get Iron Tracker or download Iron Tracker on the App Store.

2. MyFitnessPal: Calorie Counter

Best for: Tapping into a huge food database and barcode scanner to log meals in seconds.

If you want a massive food library and a barcode scanner that rarely fails, MyFitnessPal is the default. It pairs diet and exercise logging to show net calories and nutrient splits. The database covers millions of foods, so restaurant meals and packaged products pop up fast. The exercise diary syncs with wearables, which makes calorie budgeting with macros feel straightforward.

3. Lose It! – Calorie Counter

Best for: Weight-loss accountability through goal setting, macro tracking, and community support.

Lose It! hands you a calorie budget that shrinks as you lose weight, with macros and a social feed for accountability. You can celebrate wins and swap tips with others, which helps on tough days. The Snap It feature guesses serving sizes from a photo, so you spend less time on manual entries. The free version covers the essentials, while premium adds deeper insights and meal planning.

4. YAZIO Fasting & Food Tracker

Best for: Combining intermittent fasting timers with a straightforward calorie and meal diary.

YAZIO layers a fasting timer on top of a clean food diary. You see eating windows right next to your calories, and personalized meal plans with daily challenges make building a rhythm feel less like work. When your fasting window closes, logging locks, which naturally cuts out late-night snacking. It’s a practical pick if you want fasting and calorie tracking in one place without hopping between apps.

5. Cronometer: Track Nutrition

Best for: Micronutrient nerds who want lab-verified data and a complete nutrient breakdown.

Cronometer tracks up to 82 micronutrients alongside macros, using a curated, lab-verified database. Because the data isn’t filled with user-submitted entries, you see accurate vitamin and mineral tallies. The nutrient breakdown graphs are the highlight. Tap a colorful ring chart and see exactly where you’re hitting and missing targets. It’s for anyone who treats food as fuel and wants to close specific nutritional gaps.

6. MacroFactor - Macro Tracker

Best for: An adherence-neutral approach that adapts targets to your actual metabolism.

MacroFactor doesn’t cheer or scold. It just runs the numbers. Each week you log your weight and intake, and an algorithm adjusts your calorie and macro targets based on your actual metabolism. No guilt, no hype. The transparency of the calorie coaching makes it a great fit for lifters and data-driven dieters who want to leave Lifesum’s one-size-fits-all plans.

7. Calorie Counter by FatSecret

Best for: A fully free, community-backed alternative with no premium paywalls.

FatSecret delivers a food diary, exercise log, weight chart, and an active forum, all completely free. No upsells, no credit card required. The barcode scanner and meal database are free too, and the community feed is full of recipe swaps and encouragement. While the design isn’t the slickest, it’s the obvious budget pick among Lifesum alternatives if you want solid calorie counting and peer support at zero dollars.

8. Carb Manager: Keto Diet Tracker

Best for: Low-carb and keto dieters who want a specialized dashboard and recipe library.

Carb Manager is built for keto. It puts net carbs front and center next to your fat and protein targets. The meal planner and premium recipe library remove the guesswork from staying low carb. A beginner-friendly dashboard and barcode scanner that flags hidden sugars make it the tailored choice when you’re switching from Lifesum and serious about ketosis.

9. Fooducate: Nutrition Tracker

Best for: Learning what’s actually in your food through letter grades and healthier swaps.

Fooducate scans a barcode and gives the item a letter grade based on nutritional quality, not just calories. It explains why a food scored poorly and suggests better options. Families use it to teach kids about hidden sugars and processed ingredients. The grading system is the real draw, moving the focus from strict counting to understanding what you eat. It’s a smart educational Lifesum alternative.

How we picked these apps

We looked for apps that fill the gaps Lifesum leaves open: deep micronutrient tracking, fasting tools, iron-specific logging, keto support, and food-quality education. Each was tested for daily logging speed, how well they hit specific goals, platform availability, and whether the pricing was fair. Apps with aggressive upsells, unreliable databases, or missing Android or iOS versions didn’t make the cut. Iron Tracker earned the top spot because it throws out feature clutter and goes all-in on ferritin replenishment—something no other tracker does with such focus.
