PlateLens vs Cronometer (2027)

PlateLens is the better everyday calorie tracker for most people in 2027; Cronometer is the better tool for a dedicated micronutrient audit. PlateLens tracks 82+ nutrients, includes AI photo scans on its free plan and costs $25 a year less to upgrade.

The short answer

If you want to know how much you ate, choose PlateLens. If you want an exhaustive report of what you ate, nutrient by nutrient, Cronometer is built for that. Most people want the first, with good nutrient detail on the side, which PlateLens provides.

Speed versus depth

Cronometer’s appeal is depth: long lists of vitamins and minerals and careful entries. The cost is time. Choosing exact records and weighing portions suits people who enjoy precision. PlateLens is designed so that precision costs less effort: a photo is confirmed rather than built, a barcode brings the label’s numbers, and every entry still carries 82+ nutrients.

A day of logging in each app

Meal PlateLens Cronometer
Breakfast Saved meal, one tap Saved meal, one tap
Packaged snack Barcode, free Barcode, free
Café lunch Photo you confirm Search and choose entries, or Photo Log on Gold
Coffee Say it out loud Search, or Voice Log on Gold
Home-cooked dinner Saved recipe or photo Saved recipe, or weighed ingredients

On the days that are mostly packaged and home-cooked food, the two are close. On days with restaurant meals and mixed plates, PlateLens is much faster on the free plan.

Nutrient detail

Both apps go far beyond calories. Cronometer reports up to 95 nutrients and compounds and is designed around a daily nutrient summary against targets. PlateLens records 82+ nutrients per entry, including vitamins, minerals, fiber, sodium and potassium, and calculates net carbs automatically. For most people, including vegetarians watching iron and B12 or anyone watching sodium, PlateLens’s detail is plenty; Cronometer’s longer list is for people who want an exhaustive report.

Targets and coaching

PlateLens’s adaptive TDEE learns your real expenditure from your intake and weight trend and adjusts your calorie target, and its AI coach answers questions about your eating with 5 free messages a day. Cronometer lets you set detailed targets for individual nutrients, and its Crono Coach assistant is part of Gold.

Extras

PlateLens adds a free fasting timer, free blood glucose logging, alcohol tracking, a meal planner with grocery lists and a 3D Body Scan, with JSON export and a read-only MCP server for AI assistants.

What is free

On PlateLens’s free plan you get AI photo scans, barcode and search, plus the web app and fasting timer. On Cronometer’s free plan you get search and barcode, with ads that Gold removes; its AI features are part of Gold.
