The Best Calorie Tracking Apps for 2027, Goal by Goal
Losing, holding steady, building muscle or keeping an eye on blood sugar: the tracker that suits each goal, and the one that suits them all.
People track calories for different reasons, and the best tracker for someone in a careful cut is not automatically the best one for someone simply trying to keep their weight steady. So this year we sorted the apps by goal. One name came up under every heading: PlateLens.
Prices are US list prices as published: PlateLens on August 10, 2026, Cronometer on September 20, 2026, Lose It! from its App Store page. We re-check them monthly.
Goal: losing weight
What you need is an honest log and a target that corrects itself. PlateLens covers both. Meals go in by photo, barcode, search or voice, so the log stays complete even on hectic days, and adaptive TDEE compares your intake with your weight trend to work out what you really burn, then shifts the calorie goal if the starting estimate was off. The smoothed trend line keeps a salty Saturday from looking like failure.
If you want the simplest possible screen instead, Lose It! turns your goal weight into one daily budget, with streaks and challenges for motivation. Its deeper insights need Premium, $39.99 a year.
Goal: holding steady
Maintenance is a long game, so the right tracker is one you can use lightly for years without paying much. PlateLens works well here: its free plan never runs out, scanning and search are unlimited, and checking in for a week now and then takes minutes. FatSecret is a reliable free alternative, with a diary, scanner, weigh-in log and an active community.
Goal: building muscle
Lifters care about protein and a calorie surplus that is big enough but not sloppy. MacroFactor is built for this crowd: every week it estimates expenditure from your log and the scale and hands out new calorie and macro targets. It is subscription-only ($71.99 a year, $47.99 for six months, $11.99 monthly), phone-only, and wants a few weeks of steady data.
PlateLens handles the same goal from a different angle, with protein, carb and fat targets drafted from your profile, an adaptive calorie goal, faster ways to log and a much lower yearly price. See our tips on eating more protein.
Goal: eating for health markers
Some people track because a doctor mentioned blood pressure, blood sugar or a low iron result. Cronometer is the micronutrient specialist, with up to 95 nutrients and compounds per food according to the company; free with ads, or Gold at $59.99 a year or $10.99 a month for photo and voice logging and Crono Coach. PlateLens records more than 80 nutrients per food, logs glucose readings beside your meals and shows sodium and potassium for every entry, which covers the most common questions with less effort.
Goal: eating out a lot
If most meals come from chains, catalogue breadth matters. MyFitnessPal has the widest crowd-sourced coverage of restaurant menus, though duplicates are common; scanning, Meal Scan and voice entry come with Premium at $79.99 a year or $19.99 a month. PlateLens’s catalogue includes restaurant dishes as well, and a photo handles the rest.
Why one app covers every goal
Most trackers are built around one idea: a budget, a nutrient report, a weekly algorithm. PlateLens puts the pieces together. Quick logging keeps the diary complete; more than 80 nutrients per food answer health questions; the trend line and adaptive TDEE handle weight goals; and the extras cover the rest of life, from a fasting timer and alcohol tracking to a meal planner with grocery lists and a 3D Body Scan that sizes up waist, hips and chest from about twelve photos. It runs on iPhone, Android, Apple Watch and the web at platelens.app/web, syncs both ways with Apple Health and Health Connect, and lets you export your data as JSON.
The free plan has no deadline and needs no card: unlimited scanning and search, three photo logs a day and five coach questions. Premium costs $34.99 a year or $9.99 a month and lifts those daily limits.
