FatSecret’s appeal is refreshingly narrow and we’ll take it at face value: it’s free, the core tracking isn’t held hostage behind a subscription, and there’s a real web app for people who’d rather log from a keyboard than a phone. In a category where “free” increasingly means “free until you hit the paywall,” that’s a genuine differentiator. The flip side is equally plain and gets the same weight: it looks dated, it has no photo logging, and the free tier carries ads. We marked it mixed consensus because the room agrees on both halves — great if free-and-functional is the whole requirement, underwhelming if you want anything modern.

I installed it fresh, used both the phone app and the web version, and logged in it for a few weeks before writing this.

What it actually does well

The headline is the price, and unlike some rivals it holds up: the everyday calorie and macro tracking is free, and you’re not constantly bumping into a “go Premium” wall to do the basic job. For people who flatly refuse to pay for a calorie counter — and there are a lot of them — FatSecret is the honest answer, which is why it reliably surfaces in a perennial “best free app” thread in r/CICO and in the broader best-free-app discussions when someone draws a hard line at zero dollars.

The web app deserves its own mention. A lot of trackers have gone mobile-only or treat the desktop experience as an afterthought; FatSecret’s web version is genuinely usable, which matters if part of your day is at a laptop and you’d rather type your lunch than dig out your phone. Free and available on the desktop is a combination fewer apps offer than you’d think.

Where it falls short

I’m holding it to the same standard as everything else the desk reviews, so the cons carry equal weight:

  • A dated interface. It’s functional but visibly older than the polished trackers. Nothing’s broken, but the look and flow feel like a previous generation, and that first impression costs it with anyone used to a modern app.
  • No photo logging. Entry is manual — search and type. In a year when photo-based logging has become a real category, the absence is conspicuous, and it means FatSecret offers no shortcut for the meals where manual entry is the chore.
  • Ads on the free tier. The no-cost model is paid for with advertising. Premium removes the ads, but on the free tier — the whole reason most people are here — they’re part of the deal.

None of these breaks the core use case. All of them are reasons someone who cares about polish or speed will look elsewhere.

Who should pick something else

Be honest about what you actually want. Skip FatSecret if you want photo logging or a modern, polished interface more than you want a free price tag; if you’re a micronutrient purist who needs trustworthy iron, potassium and vitamin data (Cronometer is the better tool); or an advanced user chasing adaptive targets and deep analytics (MacroFactor). For those people “it’s free” doesn’t outweigh what they’re giving up.

The relevant contrast on speed is photo logging: someone who finds manual entry the thing that makes them quit, and who’s willing to consider a paid tier, often ends up on a photo logger like PlateLens instead — trading FatSecret’s free-and-web model for a faster mobile workflow. If your bottleneck is cost or desktop access, FatSecret wins that trade; if it’s the manual typing itself, it doesn’t.

What long-term users and the threads say

The recurring view is consistent: FatSecret is the app people name when the conversation is specifically about free, and it earns that slot honestly. The criticism is just as consistent and rarely about whether it works — it’s about the dated feel and the lack of modern conveniences like photo logging. There’s little drama here in either direction; it’s a steady, no-frills tool with a clear constituency. The honest summary is that FatSecret knows exactly what it is and doesn’t oversell, which is more than you can say for some flashier competitors.

Verdict

FatSecret is the genuinely-free, no-nag tracker with the bonus of a usable web app, and for someone whose first requirement is “don’t make me pay” or “let me log from my desktop,” that’s a real and honest win. The trade-offs get equal billing: the interface is dated, there’s no photo logging, and the free tier carries ads. As a no-cost, no-fuss way to count calories, it does the job without pretending to be more. As a modern experience, it doesn’t compete — and to its credit, it doesn’t claim to.
