A person answers, usually the same day.

It counts calories, but that is not what it is for. The score you build is made of behaviours you control — logging, moving, weighing in, hitting protein — and never of what you weigh. Most people find the counting becomes background within a fortnight.

Momentum dips and your level does not move at all. When you open it again there is no backlog, no summary of what you missed, and no red. You get one easy thing to do and a bonus for doing it. That is the entire design.

No. A day with one item logged counts as a logged day. Kenja would rather have six honest days than seven where two were invented, because the estimates it builds are only as good as the days you actually recorded.

Because that framing turns food into a debt and exercise into a punishment, and it does not work. Training is there because it protects muscle while you lose fat. It is never a correction for a meal.

Reasonable, and honest about not being exact. Figures come from FSANZ AUSNUT, Open Food Facts and panels typed in by people using the app. Anything estimated from a photo or description is labelled as such. Your expenditure is inferred from your own intake and weight over time, which is more useful than a formula but still an estimate.

Your scale can move over a kilo overnight on water alone. Trend weight is a fourteen-day rolling average, so it shows the direction rather than the noise. If the scale is up but the trend is down, nothing has gone wrong.

No. They save you typing — steps, workouts and weight arrive on their own if you connect Health Connect or Apple Health — but everything works without them and the app never behaves as though something is missing.

No. Not to advertisers, insurers, employers or data brokers, not in aggregate and not de-identified. Kenja is paid for by subscriptions, which is the only reason it can make that promise.

Wherever you choose, per set. On the device only, which means they are gone if the phone is, or in your account, encrypted in transit and in storage and reachable only when you are signed in. You can move a set either way, or delete everything at once.

Yes, and you should say so in settings. Kenja protects an intake floor instead of pushing you lower, raises the protein target, and watches lean mass rather than celebrating the scale. Losing weight is easy on those medications; keeping muscle is the hard part.

Yes. You can set your day to start when you wake rather than at midnight, or run a flexible day for rotating shifts. A night shift that crosses midnight stays one day.

Any time, in two forms. A complete JSON file with every entry, or a printed report with charts, nutrient tables and plain observations — the one to take to a doctor.

Tell Kenja in settings and it changes behaviour: no daily weight prompts, no calorie deficits framed as achievements, and the option to hide numbers entirely. It is not a treatment tool, and if tracking is making things worse the right answer is to stop and talk to someone.

It is Japanese for a wise or thoughtful person. The idea is an app that thinks about the boring parts so you do not have to.
