The calorie diary that stops being work.

No. It doesn't expire and it doesn't ask for a card. Barcode scanning, food search, saved meals, your charts and your whole history stay free permanently. What's rationed is the AI — three estimates a day — because that's the part that costs real money to run. It's funded by ads, which is why paid plans don't have them.

Good enough to be useful, not good enough to be gospel — and the app says which is which. Anything looked up from a barcode or a food database is marked verified. Anything the AI estimated is marked as an estimate, itemised, with the portion it assumed shown so you can correct it in a tap. Over a week, consistent slightly-wrong beats accurate-but-abandoned every time.

Everything else keeps working — search, barcodes, saved meals, re-logging anything already in your diary, all your charts. Only new AI estimates pause, and they reset the next day.

Cancel any time from Settings, in two taps — it goes through Stripe's own portal, not a form that emails somebody. Your plan runs to the end of the period you've paid for. Ask within 14 days of subscribing and you get a full refund whether you've used it or not.

No. Without one, QuicKcals estimates what you burn from your stats and then corrects that estimate as it watches your actual weight change — which for most people lands close. Connecting a WHOOP replaces that estimate with a measurement, which is sharper, and it's why that sits on Pro.

Apple Health and Android's Health Connect are a different thing: neither can be read by a website, so there's no live connection to offer. What QuicKcals does instead is accept the export file those apps already produce and read your weight history out of it — free, on every plan.

Yes. It isn't sold, and it's never given to an advertiser — nothing you log is used to target ads, here or anywhere else. Free accounts see ads, but the only thing the ad script learns is that a page was opened. On a paid plan the advertising script is never loaded at all. The privacy policy spells out exactly what goes where.

Both, really. It runs in a browser, and you can install it to your home screen, where it opens full-screen, works with no signal, and can send you reminders — like an app, without an app store between you and an update.

No, and it shouldn't be treated as it. It's a diary that estimates. If you're managing a medical condition, pregnant, under 18, or have a history of disordered eating, talk to a doctor or a registered dietitian before changing how you eat.
