A free MacroFactor alternative — for people who don't want a coaching subscription
MacroFactor is a well-regarded adaptive-nutrition-coaching app with no free tier at all — every user eventually pays. Nibble is a free, account-free calorie and food diary with one tier, no subscription, and no card required, ever.
Up front, honestly: this isn't really an apples-to-apples comparison, because MacroFactor and Nibble solve different problems. MacroFactor's whole product is its adaptive algorithm — it recalculates your real energy expenditure from your logged weight trend and intake, and its own testing found that after 3-4 weeks of consistent logging its recommendations were 120-170% more accurate than a static TDEE formula.4 That's genuinely useful if you're trying to optimize a cut, bulk, or recomp with precision. Nibble doesn't do any of that: it's a plain diary with fixed goals you set yourself, no algorithm, no coaching. If you want MacroFactor's adaptive coaching, Nibble won't replace it — that's a real, deliberate gap. If you just want a free, no-account way to log food and calories without a $6-12/month subscription, read on.

Where Nibble actually wins
- Actually free — not just a trial. MacroFactor has publicly said there will never be a free tier; every user is on a paid plan sooner or later.1 Nibble has one tier, free, with nothing paywalled.
- No card required to try it. MacroFactor's 7-day trial requires your payment details up front and auto-charges if you don't cancel in time.2 Nibble needs no card, no trial, and no cancel-before-it's-too-late deadline.
- No account, ever. MacroFactor requires an account (email/password or Google/Apple sign-in) tied to a MacroFactor ID that your data is stored under.3 Nibble has no login and no user database at all.
- Your diary stays on your device. Nibble runs no server — your log lives only in this browser's local storage, so there's no cloud account to breach or disclose.
- Nothing to install, nothing to sign up for. Nibble runs in your browser and works offline after the first load — start logging in one tap.

Where MacroFactor is the better choice
Credit where it's due: MacroFactor's adaptive-coaching algorithm is a real, tested advantage, not just marketing copy. Instead of calculating your calorie target once from a static formula, it continuously reverse-calculates your true energy expenditure from your actual logged weight trend and intake — updates begin as early as the third day of use, and MacroFactor's own testing found its recommendations were 120-170% more accurate than a standard TDEE equation after 3-4 weeks of consistent logging.4 Weekly "Check-In" coaching modules also help catch common logging mistakes before they skew your numbers. If you're actively cutting, bulking, or recomping and want your targets to adapt to your real-world results rather than a formula, that's a genuine reason to pay for MacroFactor. Nibble's fixed-goal, no-algorithm design is a deliberate simplicity-and-privacy tradeoff, not an oversight: adaptive coaching needs a server crunching your ongoing weight and intake history, which is exactly what Nibble is built to avoid.
