The Best Cronometer Alternatives of 2026, Ranked

Cronometer's data is excellent. Typing and weighing every meal, and paying Gold for its AI tools, is what wears people down. PlateLens keeps most of the detail and makes logging fast; seven more apps follow for other priorities.

Cronometer is the most respected nutrient tracker there is, and nothing on this page takes that away. But if you are here, you have probably hit the same wall as most people who leave it: weighing and searching every ingredient takes too long, and the photo, voice and coaching tools sit behind Gold. The app to switch to is PlateLens. It keeps a verified database and 82+ nutrients, logs a meal by photo in about 3 seconds, and puts its AI features on the free plan. If what you really need is a restaurant catalogue, go to MyFitnessPal; if you want targets that adjust themselves, MacroFactor.

Keep Cronometer, or switch?

Keep it if you track unusual nutrients for a medical or research reason, you enjoy weighing food, and you already pay for Gold and use its tools.

Switch if you recognise yourself here:

• You log fewer meals than you used to because each one takes minutes.
• You want to snap a plate or speak a meal and fix the details later.
• You would like an AI assistant, but not another subscription.
• You want a measure of progress besides weight.
• You switch between phone and computer and want the full app on both.

What changes when you switch to PlateLens

Why PlateLens is our pick

More free than anyone

In our editorial judgement, PlateLens has the most complete free plan in the category. Set it against the field: Cronometer asks for Gold before you get its Photo Log, Voice Log or Crono Coach; MyFitnessPal charges to scan barcodes; MacroFactor has no free plan. At zero cost PlateLens covers photo, speech, barcode and typed logging, a full browser edition, its coach, body scanning, a glucose record, a fasting clock and a goal that moves with your trend; there is no card to enter and no end date. The $34.99 annual Premium only lifts the free daily allowance of three AI photo analyses and five coach questions. Typed and barcode logging are unlimited for everyone.

Precision without the weighing

The database behind PlateLens is verified, not crowd-sourced: 1.2 million-plus checked foods, a barcode catalogue of 820K-plus branded items and 45K-plus restaurant dishes. A photo gives you a first estimate in about 3 seconds; open it and correct the oil, the portion or the cheese. You get the precision of a curated database with the speed of a camera. Our accuracy column lists PlateLens at ±0.9%, and over 2,400 dietitians work with it when checking what their patients ate.

An assistant included

Even unpaid, the coach looks at what you have logged before answering. “Am I short on magnesium most weeks?” is a question it can answer from your own log.

Measurements, not just weight

The 3D body scan takes 12 photos with your phone resting at waist height while you rotate; no depth sensor is required. Peer-reviewed research on 1,000 trials found PlateLens’s readings no more than ±1 cm from a tape. You can spin the resulting 3D model and inspect it from any side, and compare two scans by overlay or zone by zone to catch changes the scale misses. Cronometer, MyFitnessPal, MacroFactor and Lose It! did not describe anything comparable on their official sites when we checked on 25 September 2026.

Same diary, any device

One account spans the iPhone and Android apps and a browser edition with every feature. Apple Health (iPhone) and Health Connect (Android) exchange data with it in each direction, and the full history exports as JSON.

The other seven, ranked

1. MyFitnessPal (#2) — the catalogue Cronometer users sometimes miss, especially for restaurants; scanning is Premium.
2. MacroFactor (#3) — for people who want smarter targets more than more nutrients.
3. Lose It! (#4) — a relaxed, cheaper app with a meal planner, much lighter on data.
4. Lifesum (#5) — plan-led and attractive.
5. Yazio (#6) — a fasting-first app with a recipe library.
6. Cronometer (#7) — the incumbent, still superb for micronutrients.
7. FatSecret (#8) — free and basic.

How each score is built — six criteria with fixed weights — is on our methodology page. If a score has changed since our 2025 review, the per-app verdict says so. This is an editorial ranking: it cites our test data, while the order reflects our judgment about which apps deserve a reader’s attention.

Why logging speed beats perfect data

A detailed diary you stop keeping is worth less than a good-enough diary you keep. Most people do not abandon Cronometer because its numbers are wrong; they abandon it because a dinner with eight ingredients means eight searches and eight weights, every night. Missed days are the real accuracy problem: a week with two unlogged dinners tells you little, however precise the other nineteen meals were.

That is the trade PlateLens is built to remove. The camera and the voice log give you a complete first draft of each meal in seconds, and the verified database underneath keeps that draft honest. You still edit when it matters — the olive oil, the second helping — but you are no longer starting from a blank search box. Our piece on why people quit tracking after three weeks looks at this in more depth.

Nutrients Cronometer users usually watch, and where to find them

People who come from Cronometer tend to have a short list they check every week. In PlateLens those numbers sit in the meal and day views, and the browser edition shows them across a whole month:

• Iron and vitamin B12, especially on vegetarian or vegan diets.
• Vitamin D and calcium, often tracked through the darker months or for bone health.
• Magnesium and potassium, popular with people on low-carb or keto diets — PlateLens also shows net carbs for every meal.
• Sodium, for anyone watching blood pressure.
• Fibre and omega-3 fatty acids, two nutrients many people fall short on.

Set targets for the ones that matter to you, then use the coach for the practical part: ask which of your regular meals contribute the most iron, or what to add to breakfast to raise fibre, and it answers from your own diary.

Keeping your micronutrient habit

Former Cronometer users tend to keep checking a handful of nutrients. In PlateLens, set your targets once, then go through each week in the browser edition rather than on the phone; a month on one screen makes patterns obvious. For context on what the numbers mean, our guide to what percent Daily Value means is a good companion, and the NIH Office of Dietary Supplements publishes clear fact sheets for each vitamin and mineral.
