The Best Nutrition Apps of 2027

Every January, the same handful of food resolutions comes round again: more vegetables, more protein, less sugar, more fibre, fewer takeaways. They are good resolutions. What usually undoes them is not willpower but visibility. It is hard to eat more fibre when you have no idea how much you eat now.

That is the job of a nutrition app, and it is a gentler job than calorie counting. You are not chasing a number every day; you are building a picture over weeks, so you can see which resolution needs work. For 2027 we looked for the apps that make that picture easy to build and pleasant to look at.

A nutrition app for each resolution

• "More plants this year." PlateLens makes a varied plate easy to log from a photo, and its nutrient record shows whether fibre, iron and B12 keep up. If you want the most detail, Cronometer.
• "More protein." PlateLens shows the day's protein in grams against a goal set from your profile. Lifters who want weekly adjustments may prefer MacroFactor.
• "Less sugar." PlateLens records sugar alongside the rest of the label for every food, so a week's average is one glance away.
• "Eat to a plan." Lifesum hands you one, from Mediterranean to high-protein.
• "Fewer takeaways, smarter ones." PlateLens covers tens of thousands of restaurant dishes and logs anything else from a photo; MyFitnessPal's catalogue is the broadest for chains.
• "Just start." Lose It! is the gentlest first step.

Why PlateLens is our pick for 2027

The best nutrition app is the one you keep opening in March. PlateLens earns that by making the daily part almost effortless: a photo for the plate you cooked, a barcode for the snack, a quick search or a sentence for everything else, all landing in one diary. The food behind it comes from a catalogue the company describes as verified, so the numbers you build up over weeks are consistent.

The nutrition part happens quietly in the background. Each food carries more than 80 nutrient values, from fibre and sodium to potassium, magnesium, iron and calcium, and net carbs are calculated automatically. When you want to check how a resolution is going, the detail is there; when you just want to log lunch, it stays out of the way.

Around the diary, PlateLens has the extras a year of good intentions tends to need: a fasting timer for those who eat in a window, a place to log glucose readings beside meals, a meal planner that builds a grocery list, and a body scan from a dozen phone photos for anyone tracking measurements rather than weight. It runs on phones, Apple Watch and a full web app at platelens.app/web, lets you download your history as JSON, and the free plan has no end date. For the longer haul it adds adaptive TDEE, which nudges your calorie goal as your weight trend comes in, and alcohol tracking for the evenings resolutions tend to forget. Premium, at $34.99 a year (price checked August 10, 2026), mainly lifts the daily photo limit.

The close second: Cronometer

For readers who love detail, Cronometer is a wonderful tool. It goes deeper on vitamins and minerals than anything else here, and it is free to start, with ads. The trade-off is effort: entries take more care, and photo and voice logging need Gold, at $59.99 a year (checked September 20, 2026). If your 2027 resolution is about one specific nutrient, it may be the better fit.

How we chose

We compared each app's current features, plans and prices, and weighed them for a reader who wants to eat better rather than to count obsessively: how easy the daily habit is, how much nutrient detail is kept, and how pleasant the app is to come back to. Prices are US list prices with the dates shown. This list is reviewed monthly.
