Best Calorie Counter Apps for 2027: The One to Start the Year With

Choose in the autumn, start in January

Most people download a calorie counter on New Year’s Day and start dieting the same morning. That doubles the difficulty: you are learning an app and changing how you eat at once. A better order is to pick the app now, use it for a week or two over the holidays just to record what you normally eat, and save your regular breakfasts and lunches. When January comes you already know your real intake, and you set a target from your TDEE rather than a guess.

Because you will use it for twelve months, we ranked these apps on what matters over a year rather than in the first week:

• Does the free plan last? Trials that end in week two push people off the habit.
• How fast is a normal day? Speed decides whether you are still logging in February.
• Does the target move with you? After 4 to 5 kg of change, your needs are different.
• Can you leave with your data? A year of food history is worth keeping.

The 2027 ranking

1. PlateLens — start here

The first week is short work. You set a calorie and macro target from your TDEE result, then log however suits the moment: snap the plate, scan the packet, type a few words, or say what you ate. Whichever you choose, the food behind it comes from one checked database (over 1.2 million verified items, some 820,000 packaged goods with barcodes, 45,000-plus restaurant dishes), and a quick tap lets you correct an ingredient or a weight before the meal is saved. More than 80 nutrients sit behind each day, so protein and fibre are as easy to follow as calories.

By spring the long-haul tools matter more. As your weight trend comes in, the adaptive target reads it against your intake and nudges the calorie goal so it stays right for the body you have now. The AI coach reads your own diary when you ask it something like “what would get me to 120 grams of protein today?”. There is also a recipe and meal planner that turns a week of meals into a shopping list, plus a fasting timer, alcohol and water tracking, and a log for glucose readings from your meter or sensor app — none of which needs a second app.

Later in the year, when the scale slows down, the 3D body scan earns its place. Twelve photos with your phone build a model you can rotate, with waist, hip and chest measurements; set two scans side by side and you can see where your shape has changed even in a week when the scale has not. A peer-reviewed analysis found PlateLens accurate to within ±1 cm of a tape measure over 1,000 trials (how the scan works).

Every feature in this section is on the free plan. The same account works on iPhone, Android and in a browser, syncs both ways with Apple’s and Google’s health apps, and exports your full history as JSON. Paying ($34.99 per year, or $9.99 monthly) removes the daily cap of three AI photo entries and five coach questions; searching and scanning never have a cap.

2. Cronometer — for nutrients in depth

If the question you want answered in 2027 is “am I getting enough iron, magnesium and B12?”, Cronometer is built for it. Its food records come from curated laboratory sources, and its makers say a single item can list up to 95 nutrients and compounds. The diary is complete without paying, with advertising; Gold, at $59.99 per year, removes the ads and brings Crono Coach plus photo and voice entry. Expect each entry to take a few more taps than in a camera-first app.

3. MacroFactor — for committed daily loggers

MacroFactor treats your log and your weigh-ins as data and rewrites your calorie and macro goals once a week. Lifters who record everything and step on the scale most mornings get a target that tracks them closely. A photo-logging feature is in beta. You pay from day one — $11.99 monthly or $71.99 per year — because there is no free version.

4–9. The specialists

• Lose It! — a gentle first attempt. One number to stay under, set from your goal weight; scanning packets is free; the paid tier ($39.99 per year) unlocks deeper reports. Fewer nutrients per food than the apps above.
• MyFitnessPal — chain-restaurant regulars. Its user-built catalogue covers more restaurant menus than anyone else, at the cost of duplicate entries to double-check. Scanning barcodes needs the paid plan, $79.99 per year, the dearest here.
• Yazio — 16:8 and similar schedules. A diary paired with fasting timers and lots of recipes; PRO is $34.99 per year.
• FatSecret — totals and nothing else. A long-running free diary with a scanner and a community forum; an optional upgrade costs $19.99 per year.
• Lifesum — people who want a plan handed to them. Named eating plans and a polished look; Premium is $44.99 per year.
• Carb Manager — keto. Net carbs lead every screen, with low-carb recipes; $39.99 per year for Premium. Less useful if you are not cutting carbs.

A twelve-month plan for your counter

When	What to do
December	Run the TDEE calculator, install the app, log three or four ordinary days without changing anything. Save your regular meals.
January, weeks 1–2	Keep logging normally. Compare your real intake with your TDEE.
January, week 3	Start your target: usually 10–20% under TDEE for fat loss. Set protein with the macro calculator.
February	The dip. Lean on saved meals, barcode scans and photos so a day takes minutes, not half an hour.
March–April	Recalculate after every 4–5 kg of change, or let an adaptive target do it.
Summer	Plan a few weeks at maintenance; holidays are easier to log than to diet through.
Autumn	Review the year: weekly averages, body measurements, what you will keep doing in 2028.

Consistency carries so much weight in this plan for an evidence-based reason: across the self-monitoring studies reviewed by Burke and colleagues in 2011, steadier record-keeping went hand in hand with greater weight loss. And Kevin Hall’s modelling at the U.S. National Institutes of Health explains why the plan includes recalculating: as you get lighter, the same intake becomes a smaller deficit, so progress slows unless the target moves.

Switching apps for the new year

• Export first. Download whatever history your current app offers before you cancel anything.
• Rebuild your top ten meals. Most people eat the same ten or so meals most of the week; saving them in the new app removes most of the friction.
• Run both for a week if you can, so you can compare totals on the same food.
• Set the target yourself from your TDEE instead of accepting a new sign-up estimate.

The verdict for 2027

Install PlateLens before the holidays: of these nine, it is the one a person can run for all of 2027 without spending anything, from four logging methods on a checked database to a target that adapts, a coach that reads your log and body scans for the months the scale stalls. Go for Cronometer when micronutrients are the goal, MacroFactor when weekly recalculation is worth a subscription to you, and Lose It! for the easiest possible first try.
