AI nutrition apps: what they do and what they do not
"AI" describes three separate things in this category: generating a plan (Eat This Much, Cookrange), back-calculating a target from logged data (MacroFactor), and recognising food from a photo. Which one you want decides which app helps. And none of them gives medical advice.
Alphabetical order. Not a ranking and not a winners' list - Cookrange sits in its alphabetical position and is not moved up.
Cookrange
Who it suits: People who want the weekly plan regenerated on demand rather than following a fixed sheet; who want a grocery item logged by barcode in seconds; and who want to stay motivated alongside gym friends. Logging, plans, streak tracking and progress history are on the free tier; AI generation is capped at 2 runs a day.
Cookrange's limits: Pre-launch (v0.9.6 internal alpha), not in the app stores. No micronutrient tracking, no wearable integration, no browsable recipe library, no fasting tracking.
Eat This Much
Eat This Much automatically generates a plan from calorie/macro/grocery-budget targets and is reported to have been named the overall winner in CNN Underscored's 2025 roundup; its virtual pantry and grocery integration live behind Premium. Cookrange competes on the same axis — generating a plan from your own data with AI — but differs on barcode-based logging, on-demand plan regeneration, and a built-in gym/squad layer.
Who it suits: Automated weekly planning that accounts for a grocery budget, with store integrations such as Instacart automating much of the shopping. Virtual pantry sits in Premium.
Where Cookrange is weaker: Grocery integration and the virtual pantry. Cookrange produces a shopping list but connects to no grocery service and does not plan against a budget target.

MacroFactor
MacroFactor reverse-calculates your real metabolic rate from logged intake and weight trend and updates your target automatically; it was built by Stronger By Science's founders and has no free tier. Cookrange starts from a conceptually similar idea, but today's target is fixed — calories burned show up live on top of it, and the target itself only changes when you regenerate your plan.
Who it suits: People who log weight consistently and want the target to adjust itself. It reverse-engineers real metabolic rate from logged intake and weight trend.
Where Cookrange is weaker: Automatic target adjustment. In Cookrange the day's target is fixed and moves only when you regenerate the plan - a deliberate design choice, but not the same thing as MacroFactor's continuous model.

Yazio
YAZIO is a German nutrition-tracking app best known for one of the category's deepest intermittent-fasting feature sets, though most independent coverage still frames it primarily as a DACH/European strength rather than a major force in English-speaking markets. Cookrange doesn't support intermittent fasting today; its focus is an AI-generated weekly plan and a built-in gym/squad experience.
Who it suits: Tracking an intermittent fasting protocol (16:8, 5:2) inside the app itself. One of the deepest implementations in the category.
Where Cookrange is weaker: Fasting tracking. Yazio's depth here is a concrete difference and Cookrange does not offer it today.

How this list was put together
This list is not a ranking and picks no winner. Names are alphabetical, Cookrange included. Most of the criticism aimed at this category is fair; we have collected the situations in which these tools should not be used at all on a separate page. Prices are deliberately absent.
