EOV Fitness Weight v1.0.0

A weight diary for Windows 10 and 11. One number a day, and the app turns it into a chart, a BMI reading, a trend and a forecast for the day you reach your goal. Everything is kept in a single folder on your own disk: the app has no account, no cloud and no network code at all.

Why bother

A single reading on the scale means almost nothing on its own. Weight swings with water, salt, the time of day and last night's dinner, and over a short stretch that noise easily drowns out the actual result. The only way to know whether you are getting somewhere is the history — and the history has to live somewhere you cannot lose it along with somebody else's service.

What it does

Logging a weigh-in takes two seconds: press plus, and the date and time are already filled in — you just confirm the number. Entries can be backdated to any day you happen to remember.

The chart draws your history over a week, a month, three months, a year, three years, or all of it. Periods are counted back from today; the mouse wheel zooms into a stretch and dragging pans across it.

Change cards show what happened over the past week, month and year, and compare each against the previous stretch of the same length.

BMI is computed from your height and shown not just as a number but as a band — from underweight to obese — along with the healthy weight range for that height.

If your scale measures body fat, you can log that percentage next to the weight: turn on "Track body fat" in the settings (it is off by default). The field may be left empty; the log gains a "Fat, %" column, the home screen shows the latest reading, and the value travels with CSV and backups.

A forecast that does not pretend

A goal is a type (lose, maintain, gain), a target weight, and the day you count your journey from. From there the app answers twice, independently: once across the whole journey, once over the last 2–26 weeks, with the window set by buttons on the card itself.

Each side either names an expected date or says plainly that there isn't one: goal reached, not getting closer, over ten years, not enough data yet — and in the last case it tells you how many entries are needed and how many you have.

When the two answers disagree, the short window is the more honest one about right now, and the long one about the journey as a whole. A plateau usually shows up first as the gap between them, earlier than you would spot it on the chart.

Gaps stay visible

If you skipped the scale for a month, the chart will not join two distant points with a confident solid line. The gap is drawn dashed instead. On a history kept over years — with dense stretches and long silences in it — the difference is obvious at a glance, and it is more honest than an even line from edge to edge.

Progress photos

Any day can have a photo attached. In the gallery it sits next to the weight recorded for that date, so "eight kilos down" stops being only a number. Your original file stays exactly where it was: the app copies it into its own folder.

More than one person

Profiles switch with a single click on the avatars in the top-right corner. Each has its own history, height and age, its own goal and its own photos. A whole family logs into one app without the numbers ever mixing.

The data stays yours

Everything lives in %LOCALAPPDATA%\EOVFitnessWeight: an ordinary SQLite file and a folder of photos. Any SQLite viewer opens the database, and the folder can simply be copied to another machine — which is exactly what the backup does.

There is CSV import and export, ZIP backups, and a mirror of the database kept next to the executable: land on a new machine with empty data and the app offers to bring itself back from that mirror.

The WEIGHTTABLE_DATA environment variable moves the database and the photos to any folder you name — a USB stick, for instance.

Help is one key away

F1 opens an illustrated manual in the language of the interface, English or Russian. Every screenshot carries callouts — a number, a thin line to the spot and a caption saying what it is for. The manual sits next to the app as plain HTML pages and opens in your browser without an internet connection.

What it does not do

It does not count calories, track workouts, build meal plans or hand out health advice. It is a weight diary, not a coach.

It does not sync across devices and there is no mobile version. There is no network code in it whatsoever — a deliberate limit, not an unfinished feature.

It does not diagnose anything. BMI is a crude yardstick that knows nothing about your muscle mass, and the app presents it as a reference, not a verdict.

It does not promise results. The forecast is arithmetic over your own entries, and it moves as they do.
