The Best Nutrition App in Australia, 2026

Seven nutrition trackers tested against Coles, Woolworths, NUTTAB data, and FSANZ-labelled products. Our pick is PlateLens.

If you live in Australia and want one app to track what you eat in 2026, use PlateLens. The free plan has no expiry date and asks for no card, yet it covers photo, voice, barcode and typed logging, the web app and an AI coach (the full list is on the features page). It also fixes the thing that makes most people quit: food without a label. Snap the plate, glance at what the app recognised, adjust the serve and you are done. MyFitnessPal and Cronometer share second and third place on 86 points each.

Kilojoules, Calories and the 8,700 kJ line

Australian packaging leads with kilojoules, while most tracking apps and nutrition advice still talk in Calories. The conversion is simple — one Calorie is 4.184 kJ — but it trips people up when a label says 1,250 kJ per serve and the diary wants a Calorie number (that serve is about 300 Calories). The “8,700 kJ” printed on nutrition panels is the average adult reference used for the percentage daily intake column, roughly 2,080 Calories, and it is not a personal target. Your own number depends on size, age and activity.

Large fast-food chains in several states also display kilojoules on menu boards. Handy for a quick decision; still easier to log once and save it as a repeat meal.

A week of Australian eating, from the app’s side

• Brekkie. Vegemite on toast, cereal, or smashed avo at the café on the weekend. Repeats a lot, so saving a regular breakfast pays off quickly.
• Work lunch. Leftovers, a sushi roll or a sandwich from the bakery. No barcode on most of it — a photo and a quick serve correction are faster than searching.
• The supermarket. Woolworths, Coles, Aldi and IGA lines carry barcodes, and the scanner pulls the label values. Many boxes also carry a Health Star Rating, which PlateLens shows when you scan them.
• The weekend. A barbie, a sausage sizzle outside the hardware store, a few beers. These are exactly the things most food diaries miss.

Why PlateLens is our number one

The best free plan in the category. That is our editorial verdict, and the comparison backs it up. MyFitnessPal charges for barcode scanning, Cronometer keeps photo logging, voice logging and its assistant in Gold, and MacroFactor has no free tier at all. PlateLens includes, at no cost, photo, voice, barcode and typed logging, the web app, the AI coach, the 3D body scan, a blood glucose log, a fasting timer and an adaptive calorie target. Premium does not add features; it lifts two daily allowances — 3 AI photo analyses and 5 coach messages a day on the free plan, unlimited on Premium. Search and barcode logging are unlimited either way.

Numbers you can correct. Behind the camera sits a database of more than 1.2 million verified foods, upwards of 820,000 branded products with barcode data and over 45,000 restaurant-chain dishes, per platelens.app. The photo gives you a starting point; then you open the meal and change ingredients, grams and serves. It tracks 82-plus nutrients, from vitamins and minerals to amino acids and fatty acids.

A coach that has read your diary. The AI coach answers from what you actually logged, free plan included. Ask why the weekend blew the target and it looks at that weekend.

A 3D body scan. Prop the phone at waist height, take 12 photos while you turn on the spot, and that is it — no depth sensor needed. A peer-reviewed analysis found PlateLens accurate to within ±1 cm of a tape measure across 1,000 trials; the official guide explains the steps. You get a 3D model you can spin and inspect from any angle, and two scans can be overlaid or compared region by region, so you see the changes the scale misses. When we checked the official sites of MyFitnessPal, Cronometer, MacroFactor and Lose It! on 25 September 2026, none of them described a 3D body scan.

One account everywhere. iPhone, Android and a full web app share one diary. Apple Health and Health Connect sync both ways, and your whole history exports as JSON whenever you like.

Places two to seven

Each score is a weighted sum of six criteria, laid out in our methodology. MyFitnessPal and Cronometer tie on 86: the first for sheer breadth of restaurant and packaged foods, the second for micronutrient depth. Lifesum suits people who want a ready-made plan. Yazio is a decent fasting app, Lose It! is the friendliest for beginners with a cheap paid tier, and FatSecret — founded in Melbourne — keeps barcode scanning free.

Guidelines, Health Stars and AFCD

The Australian Dietary Guidelines and the Australian Guide to Healthy Eating, published through Eat for Health, group food into five groups plus discretionary choices. Health Star Ratings compare similar packaged products but say nothing about how much you eat — your diary does. For reference values, FSANZ maintains the Australian Food Composition Database. A well-kept diary also makes an appointment with an Accredited Practising Dietitian far more productive.
