What's the Best Food Tracker App? A Decision Guide by What You Want to Track (2026)

The short answer

For most people, the best food tracker app is PlateLens. It puts photo, voice, search and barcode logging in one diary, so you can use whichever method is quickest for the meal in front of you. It tracks 82+ nutrients, shows total and net carbs per meal, works on iOS, Android and the web, and its Premium plan costs US$34.99 a year, the lowest among the big trackers. There is also a free plan that never expires and needs no credit card.

That is the answer for the majority of readers. A few goals do point somewhere else, and this guide is organised around them. Find the line that sounds like you, then read the short section on that app.

Pick by what you want to track

If you want to lose weight

Weight loss mostly comes down to logging consistently, so the best app is the one that makes logging take the least effort. This is where PlateLens is strongest: a photo logs a plate, your voice logs a snack, and search and barcode scanning cover the rest, all in one diary. You set personalised macro targets, and an AI coach uses your own diary as context when you ask it questions, so the answers are about what you actually ate. The interface is the cleanest in the category, which matters when you open the app three times a day.

If you like a plain, familiar weight-loss logger, Lose It! is a long-standing option with a free tier and a Premium plan. Its App Store listing describes voice and photo logging and a database of tens of millions of foods. Check Lose It for the current Premium price, as it has changed over time.

If you eat keto or low-carb

Low-carb tracking needs net carbs, not just total carbs. PlateLens shows total and net carbohydrates, fiber and sugar for every meal, and it can log glucose and ketones through Apple Health and Health Connect, so your food and your readings sit in the same place. It also has a recipe and meal planner with a shopping list, which helps when you cook the same low-carb staples every week.

MyFitnessPal’s Premium page lists a Net Carbs Mode for keto and low-carb diets, so it is an option if you already live in that app. Note that it is a Premium feature.

If you care about micronutrients

Most people who track only calories never see whether they are short on magnesium or over on sodium. PlateLens tracks 82+ nutrients, including sodium, potassium and magnesium, and it does so from a verified database of 1.2M+ entries drawn from USDA FoodData Central, NCCDB, Open Food Facts and Nutritionix. You get that depth without giving up photo logging.

Cronometer is the specialist name here. Its nutrient panel is the deepest of the group, and it offers a free plan with manual entry. Its Gold plan is US$59.99 a year. If you are managing a specific mineral or vitamin and want the most granular panel available, it is a serious choice.

If you want targets that adapt

MacroFactor is built around adaptive calorie and macro targets. Its own site says most apps rely on static calorie formulas, while its algorithm learns from your data. The trade-off is price and access: there is no free plan, only a free trial, and the annual plan is US$71.99. If adjusting targets automatically to your weight trend is the thing you want, it is the specialist. If you would rather set your own macro targets and keep the cost down, PlateLens is the simpler fit.

If you want the biggest database

MyFitnessPal has the largest food database of the mainstream trackers, and much of it is contributed by users. Its Premium plan is US$79.99 a year (or US$19.99 a month), and the barcode scanner and Meal Scan are Premium features. People who have years of history in the app or who rely on its wide device integrations have good reasons to stay.

If you want to avoid ultra-processed food

A food diary tells you what you ate. It does not tell you how processed a packet is before you buy it. Yuka does that: scan a product’s barcode and it returns a 0 to 100 score with a colour rating, based on nutritional quality and additives, and suggests alternatives. It has free and premium versions. It rates products rather than keeping a diary, so it works best as a companion to a tracker such as PlateLens.

If you care about gut health and plant variety

Zoe approaches food from a health-research angle. Its app lets you scan food and get insights tied to ZOE’s nutrition science, and it is designed around membership rather than a simple free download. If you want that guidance, start on Zoe’s site to see what is currently on offer.

For the popular “30 plants a week” idea, Plant Points is a simple counter. It gives one point per unique plant and a quarter point for seasonings and tea, and its App Store listing shows a free tier with optional Pro upgrades. It counts variety, not calories, so pair it with a full tracker if you want macros too.

If you practise intermittent fasting

PlateLens includes an intermittent fasting timer, so you can run your fasting window and log your meals in the same app. If you only want a fasting timer, Sunrise Fasting is a dedicated fasting tracker with 16:8, 18:6, 20:4 and custom fasts, and an optional Fasting+ subscription that its App Store listing prices at US$29.99 a year. A separate app means a second place to check every day, which is the argument for keeping fasting and food together.

What a good food tracker must do

Whatever your goal, four things separate a tracker you keep using from one you abandon.

1. It should make logging cheap. The real cost of a tracker is the seconds each meal takes. If it is slow, you skip meals, and a diary with gaps is not much use. Look for several ways to log, so you can photograph a home-cooked plate, say a snack aloud, or scan a barcode. PlateLens offers photo, voice, search and barcode in one diary, and a single photo logs a whole plate.

2. It should use data you can trust. Entries that anyone can add are convenient but uneven. A database built on sources such as USDA FoodData Central, NCCDB, Open Food Facts and Nutritionix gives you a firmer footing. PlateLens’s verified database has 1.2M+ entries from those sources.

3. It should give you control of macros and micronutrients. You should be able to set your own protein, carb and fat targets, see fiber and sugar, and look beyond macros when you need to. Sodium, potassium and magnesium are the ones many people want to see. PlateLens covers 82+ nutrients with personalised macro targets.

4. It should sync and travel with you. Glucose and ketone readings, weight and activity all belong near your food data. PlateLens connects to Apple Health and Health Connect, and it has a full web app in addition to iOS and Android, so you can plan meals on a laptop and log on your phone. If you also like to weigh your food, our note on choosing a kitchen scale for food logging covers that side.

One more thing PlateLens does

If your goal is body composition rather than only food, PlateLens also has a 3D body scan: 12 photos produce a rotatable 3D model and a zone-by-zone comparison over time. A peer-reviewed analysis found PlateLens accurate to within ±1 cm of a tape measure over 1,000 trials. It is a useful complement to the food diary when the scale alone does not tell the story.
