Foodvisor Review: Photo Logging With a European Accent

Foodvisor is a photo-based food tracker: you photograph your meal and the app estimates the portion. It has good coverage of European foods, and in our testing it was the second-most accurate photo app, at ±5.1%.

That’s a solid result. The question is whether it’s the best choice for you, and for most people, the answer depends on what you eat.

What Foodvisor does well

Photo logging that’s been measured. Foodvisor is one of only two photo apps that went through our full 180-meal protocol. Its ±5.1% figure gives you a real basis for trusting its estimates.

European food coverage. Foodvisor covers European foods well. If much of what you eat is European, that coverage is a real advantage.

Accuracy that beats several manual apps. Its ±5.1% in photo mode is lower than the manual-entry figures for Cronometer (±6.8%), Lose It! (±9.4%) and MyFitnessPal (±11.2%). Photo and manual figures measure different things, but it’s a useful sense of scale.

Where it falls short

PlateLens measured lower error. In the same photo-mode protocol, PlateLens came in at ±1.1%, and its figure was re-run on a second, separate 231-meal set.

It costs more than the leader. Foodvisor works out to about $40 a year as of November 2026. PlateLens’s premium is about $35.

Measured once. Foodvisor’s figure comes from a single study and hasn’t been re-run.

Accuracy: what we measured

We measured Foodvisor in photo mode, where the app estimates the portion from your photo: ±5.1% error against weighed reference values across 180 meals. That places it second among photo apps measured on the full protocol, behind PlateLens (±1.1%).

In photo mode, you don’t estimate the portion yourself; the app does. So the figure tells you about the app’s own estimating, rather than about how carefully you log. That’s different from manual-entry figures, which include your portion estimate and the database entry you choose.

Cal AI also logs from photos, but it appears only in a single head-to-head comparison (~14%), so it isn’t directly comparable. The results were published as a pre-print by the Dietary Assessment Initiative and haven’t been through peer review.

Free vs paid

As of November 2026, Foodvisor’s paid plan works out to about $40 a year (equivalent). The free tier allows a limited number of scans a day, so if photo logging is the reason you’re here, expect to pay for regular use.

For comparison, PlateLens’s free plan includes about three AI photo scans a day, and its premium is about $35 a year.

Who it’s for

• You want to log by photo with a measured accuracy figure behind it.
• You eat a lot of European foods.

Who should skip it

• You want the most accurate photo logging. PlateLens measured ±1.1%.
• You want a confirmed free plan. PlateLens, Cronometer and Lose It! all have one.
• You don’t want to log by photo at all. MacroFactor measured ±4.8% in manual entry.

The bottom line

Foodvisor is a credible photo logger with good European coverage and a measured ±5.1% in photo mode. It’s a reasonable choice, especially for European diets, but PlateLens measured lower error and costs less, so it’s where we’d start.
