MetaSelf

A personal, offline-first Android fitness tracker. Describe a meal in plain words; the numbers follow.

What it does

Logging by description

Write what you ate, in English or Hebrew. It comes back as one row per component, each carrying the portion assumed and how sure it was — never a single unarguable total.

Barcodes

Scan a packet and get the manufacturer's own label, via Open Food Facts. A product scanned once works afterwards with no signal at all.

A target that checks itself

Computed from your body and your goal, then corrected by what your weight actually does. Most apps guess once and never look again.

Weight as a trend

Smoothed, so a salty Sunday reads as noise rather than a setback. The daily target follows it, and says on screen what changed and why.

Movement that isn't double-counted

Only movement above your own usual day earns anything, discounted and capped. An ordinary Tuesday is worth nothing; a long hike is worth a snack.

A health record of your own

Steps, distance, heart rate, sleep and workouts, copied from Health Connect and kept on the phone. A walk two apps both recorded shows once, each figure saying where it came from.

A trainer, when you ask

Plan the next session, then say how it felt and get feedback. It sees your sessions and totals, never your meals or your sleep, and its words are labelled advice.

Your data, yours

Everything lives on the phone. Export it to one readable file whenever you like, or have a copy written automatically to a folder you choose or to your own Google Drive.

How it thinks

Every stored number records where it came from — typed, estimated, read off a label, or repeated — so an estimate can never quietly become a measurement. The arithmetic behind the daily target is shown rather than asserted.

Going over is stated as a plain fact — "210 kcal over", "you ate over 11h; your ratio allows 10h" — in the same ink as everything else, never as a reproach. There is no message anywhere in the app for a failure: no broken streak, nothing red on a day you cannot change.

MetaSelf is a personal project, written for one person. It is not on any app store, has no accounts, no analytics and no advertising, and there is no server behind it. What leaves the phone, and when, is listed in full on the privacy page.

Not medical advice

Calorie and macronutrient targets come from population formulas carrying real error bars, and nutrition figures come from AI estimates and a community food database. Both are often approximately right and sometimes wrong. The trainer is an AI model too, not a coach. Nothing here is medical, dietary or training advice — see a qualified professional for that.
