The deepest database. Or something that reads it.

Cronometer's verified nutrient database is the best in the category and this page says so in the first paragraph. What POWR offers is not a deeper one. It is a diary that gets read back to you, with a Pro coach that discusses your logged meals.

Side by side

Every POWR cell is a fact checkable on the page that owns it. Every cell in the other column is either a structural fact that changes on a scale of years, or a note telling you to check for yourself.

The database row is the one to read twice. It is the row POWR loses, it is the row most people are choosing on, and it is stated here rather than left out.
	POWR	Cronometer
Nutrient database depth (POWR loses)	Good, and smaller. Barcode, search, manual entry, and saved meals.	The deepest verified nutrient database in the category. It is the reason people use it.
Micronutrients on the free tier	Every entry, with %DV where a reference value exists.	Check theirs — this page will not quote a tier that can change next week.
Something reads the diary back	On Pro, the coach discusses the food you logged in plain language. Review the ingredients and portions first; an AI interpretation can be wrong.	Reports and charts over your own data. No coach reading a single meal back to you.
Our approach	Our approach explains the evidence standards, practical principles, and limits of POWR guidance.	Check theirs — this page will not quote a tier that can change next week.
Where the numbers come from	The coach uses relevant information from your logs. AI responses can contain errors, so check important details and do not use them for medical decisions.	Arithmetic over database values.
Bloodwork	93 biomarkers read from a lab PDF or a photo, every transcribed row reviewed before it saves.	Check theirs — this page will not quote a tier that can change next week.
Recovery, training plans, workout detection	In the app, read from the same Apple Health ledger as the diary.	Check theirs — this page will not quote a tier that can change next week.
Platforms (POWR loses)	iPhone only. An Android app is roadmap, not release.	iPhone, Android, and the web.

Where Cronometer wins

The data. Cronometer's verified nutrient database is the deepest in the category, its provenance is the reason serious trackers use it, and POWR does not match it. POWR carries micronutrients on every free entry with %DV where a reference value exists, which is a different claim from having the best-sourced value for every food.

On Pro, the coach discusses the food you logged in plain language. Review the ingredients and portions first; an AI interpretation can be wrong.

And Cronometer runs on Android and in a browser. POWR runs on an iPhone. If the exact nutrient value is the deliverable, or you are not on an iPhone, this is a short decision.

Pick Cronometer instead if

Any one of these is enough. They are not weighed against a list of POWR's advantages, because that is how a real decision works.

The precise nutrient value is the deliverable, and provenance matters more than commentary.
You are on Android, or you log from a desktop browser.
You do not want an opinion about your food, only the numbers.

FAQ

Does POWR match Cronometer for nutrient depth?

No. Cronometer's verified database is deeper and better sourced. POWR holds calories, macros, vitamins, minerals, and ingredient-level data on every free entry, which covers most questions, and adds photo logging on Pro for food no database has. If the exact sourced value is what you are after, Cronometer is where it lives.

What does POWR add that Cronometer does not?

POWR brings meal discussion on Pro together with workout recording, training plans, recovery, and bloodwork. Compare that connected workflow with the nutrient database and reporting you use in Cronometer; check its publisher for current capabilities.

Can I run both?

Yes. HealthKit is a shared ledger and POWR is one more reader of it. POWR writes nutrition, workouts, water, and weight to Health; if another app is writing workouts or sleep there, POWR reads those too. Nutrition is the one category POWR will not read in, so the two diaries stay separate.

Where is the score?

POWR does not display a food grade. On Pro, the coach discusses your meal in language, alongside its nutrition information.
