POWR charges for the camera. Start there, not at the end.

Photo logging is POWR Pro. There is no free scan and no trial, so you cannot photograph a meal in POWR without paying, and a comparison page that saved that for the small print would not be worth reading. Here it is first, and then what the same photograph produces once you are inside.

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 first row is the one POWR loses, and it is first for that reason. Everything below it is what the paid camera is attached to.

The row POWR loses

Photo logging is POWR Pro. A stranger cannot photograph one meal in POWR without paying, because there is no free AI allowance and no trial. Arriving here from a photo scanner, that is the whole objection, and no amount of copy underneath it changes the shape of the problem.

What the free tier does include is the entire deterministic half: unlimited barcode scanning, database search and manual entry, the full nutrition breakdown on every entry with vitamins, minerals and ingredient data, and calorie and macro targets that recalculate weekly from your own logs and weigh-ins. That part is free because it costs us nothing to run. The AI is metered because it does not.

If a free photo estimate is what decides it, check what each free tier currently includes and pick accordingly. POWR's is published in full, including the sentence that says Free has no AI at all.

Pick Cal AI 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.

A calorie number under a photograph is the whole job.
You want to photograph a meal without paying for a subscription.
You want less app around the camera.

FAQ

What is a Cal AI alternative that also builds workouts?

POWR is one iPhone option. Its Pro plan combines editable AI food logging with workout building, periodized training plans, recovery, and coach chat. POWR has no free AI scans or trial, so choose it for the connected product rather than for a free camera allowance.

Can I try POWR's photo logging for free?

No. There is no free AI allowance and no trial, so photo logging, chat, insights, and the coach's read all require POWR Pro. The free tier is the deterministic half: barcode, search, manual entry, the full nutrition breakdown on every entry, and adaptive calorie and macro targets. Pricing states it plainly.

Which app's photo estimate is more accurate?

This page will not claim it. Both apps estimate from a photograph, any published accuracy figures are measured on different data and different plates, and none of them tells you anything about your dinner. What POWR commits to is narrower and checkable: you see the estimate, you can correct every part of it, and nothing counts until you do.

What does POWR do with the photo afterwards?

It produces an editable draft you review, and the meal is written to Apple Health once you save it. Health data is encrypted at rest, never sold, and the AI consent switch gates every model call. The switch, the boundary, and the audit trail.

Is POWR just a calorie counter with more screens?

It is a food diary with the nutrition breakdown on every free entry, plus recovery, training plans, workout detection, and bloodwork on the same ledger. Whether that is more app than you want is a fair question, and if a single number under a photograph is the job, the answer is probably yes.
