Best Calorie Tracking Apps for 2027

Logging a single day tells you very little. Line up thirty of them beside your weight, though, and the picture changes: you can tell if the plan works, what to change and by how much. That is calorie tracking, and it is where apps really differ. For 2027, PlateLens does it best for most people, with the easiest daily logging and the most useful long view.

Unsure what TDEE or BMR mean? Those two explainers come first.

What a month of tracking should show you

• A weight trend instead of daily noise. Water, salt and carbohydrates can move the scale by a kilo overnight. A smoothed line shows the real direction.
• Your average intake. Seven-day and thirty-day averages matter; one Tuesday does not.
• Whether your target fits. If you are hitting your goal but your weight isn’t doing what you expected, the target needs adjusting, ideally by the app itself.
• Patterns. Weekends, late evenings and busy days all leave fingerprints in a month of data.

Plans and prices below are as each company publishes them, with the date we recorded them; we re-check every month.

1. PlateLens: best calorie tracking app for 2027

PlateLens treats each day’s log as raw material for something more useful. Logging itself is quick: photograph the plate and confirm what the app identified, scan a packet, search by name or dictate it, and everything lands in one diary. Then the tracking views take over. Weigh-ins are smoothed into a trend line, so a salty dinner doesn’t look like a setback, and your intake is shown against your target by day, week and month.

The calorie target itself isn’t fixed. Adaptive TDEE studies how your intake and your weight trend relate, estimates the energy you actually burn, and moves your goal when the first estimate turns out high or low. For a proper look back, the browser version puts a whole month on a big screen, and an export in Settings saves your full history as JSON.

Around that core you’ll find fasting windows (16:8, 14:10 or your own), glucose readings logged beside meals, alcohol tracking, recipes with a meal planner that writes the grocery list, and a 3D Body Scan that estimates waist, hip and chest from roughly twelve phone photos, handy when the scale stalls but your shape is changing. It runs on iPhone, Android and Apple Watch and shares activity, exercise and scale readings both ways with the health apps on your phone.

Plans: the free tier never expires and asks for no card. Scanning and searching are unlimited, and three photo logs a day are included. Premium, listed at $34.99 a year or $9.99 a month on 10 August 2026, makes photo logging and coach questions unlimited.

2. Lose It!: the simplest budget

Lose It! keeps tracking approachable. It converts your goal into one daily calorie budget, shows how each day compares and uses streaks and challenges to keep you logging. Snap It and a barcode scanner speed up entries. Deeper trend reports and insights are part of Premium, which the App Store lists at $39.99 yearly, and foods carry fewer nutrient values than in PlateLens.

3. MyFitnessPal: reach and integrations

MyFitnessPal’s tracking strength is reach: an enormous member-built catalogue and connections to a long list of fitness devices and apps, useful if your steps and workouts live somewhere else. Look-alike entries that disagree turn up often, so choose carefully. Scanning, Meal Scan and spoken logging are paid features: $79.99 yearly or $19.99 monthly.

4. YAZIO: tracking with fasting built in

YAZIO, a German app, pairs a calorie diary and scanner with intermittent-fasting tools and a recipe library, and it is especially good with European supermarket products. Many of its plans and analyses live in YAZIO PRO, priced by country.

5. MacroFactor: weekly paid coaching

MacroFactor’s whole design is the weekly check-in: it reviews your intake and weigh-ins, estimates expenditure and issues fresh calorie and macro targets. Lifters running a cut or bulk value that hands-off adjustment. It is subscription-only ($71.99 a year, $47.99 per six months, $11.99 a month), has no browser version, and needs several weeks of steady logging before the numbers settle.

MacroFactor or PlateLens? The core idea is shared: each estimates your true daily burn from the food log and the weight curve, then corrects the calorie goal. MacroFactor builds the whole product around that check-in and bills you from the first day. PlateLens wraps the same learning goal in faster logging (photos and voice included), a free tier, a browser version and a yearly price under half of MacroFactor’s.

6. Cronometer: nutrients in the picture

Cronometer suits trackers who want vitamins and minerals alongside calories; the company counts as many as 95 nutrients and compounds per item. The free tier scans barcodes between adverts, and Gold ($59.99 yearly or $10.99 monthly, noted 20 September 2026) adds photo and voice entry plus Crono Coach. Entries take more care than in a photo-first tracker.

Reading your numbers: three common situations

Your weight is dropping faster than planned. If you lose more than about 1% of your body weight a week for several weeks running, eat a little more, especially protein, to protect muscle. Our guide to how much protein you need gives the ranges.

Your weight is flat although you hit your target. First look for what is missing from the log: oils, drinks, bites while cooking. If the log is complete, your real expenditure is lower than the estimate. Trim 100 to 200 calories, or leave the adjustment to an adaptive goal.

Weekends undo the week. Look at Saturday and Sunday on their own. Two 900-calorie surpluses cancel out five days of a 350-calorie deficit. Planning one bigger meal usually works better than grazing all weekend.

Our recommendation

Start with PlateLens: log for four weeks, step on the scale most mornings and let the trend and the adaptive target do the interpreting. Lose It! is the gentlest alternative, MyFitnessPal suits people who eat out a lot, YAZIO fits fasting fans in Europe, MacroFactor is for paid weekly coaching, and Cronometer is for nutrient detail.

Good tracking brings clarity. If it begins to feel like pressure, pause, and speak with your doctor or a registered dietitian if your eating worries you.
