Weight Tracker: Daily Weigh In

A weight tracker built around one honest idea: your daily weigh-in is noisy, and the trend underneath it is what actually tells you something.

Step on the scale, open the app, and the number pad is already filled in with your last weight. Nudge it with the ± buttons or type the new one, tap save, and you're done — about two seconds. Your weigh-in lands as a dot on the chart, your streak ticks up, and the smoothed trend line redraws.

WHY A TREND LINE
Weight moves with water, food, salt and time of day. Two pounds can arrive overnight and leave again by Thursday. Weight Tracker draws a moving average through your weight log so a single heavy day nudges the line instead of jumping it — and it always keeps your real weigh-ins on the chart alongside it. The line never replaces your data.

WHAT YOU GET
• A two-second daily weigh-in with the pad pre-filled from your last entry
• Your weight trend as a smoothed moving-average line over your daily dots
• A pace figure in plain numbers — how much per week your weight log is actually moving
• Goal pacing: set your own goal weight and date, and see the date your current pace would reach it
• Milestone markers every 5 lb / 2.5 kg between where you started and the goal you chose
• Streaks and a calendar heatmap, so the habit is visible
• A full weight log you can scroll, edit and correct
• Charts over 30 days, 90 days, a year, or everything you've ever logged
• BMI, if you choose to enter your height
• Progress photos, kept on your device
• CSV export and a backup file, so your weight log is always yours
• kg, lb or stone — switch any time without touching your history

A DAILY WEIGH-IN, IF YOU WANT ONE
Turn on one optional reminder at a time you pick — morning, before bed, whenever you actually stand on the scale — and the app will nudge you once a day to weigh in. One reminder, never more, and off again in a tap. The streak and the calendar heatmap do the rest: a weight tracker only works if you use it, and the easiest way is to make it the same two seconds each day.

UNITS THAT ACTUALLY SWITCH
Your history is stored once and converted for display, so changing between kg, lb and stone never rewrites or rounds a number you already logged. Weigh in in pounds, review in kilograms, and nothing drifts.

PRIVATE, OFFLINE, NO ACCOUNT
There is no sign-up, no login and no server. Your weigh-ins, your goal, your settings and any progress photos stay on your phone, because this weight tracker has nowhere to send them. It works on a plane, in a basement gym, and with the wifi off. Nothing to delete from a cloud later, because your log was never uploaded.

WHAT THIS APP IS NOT
Weight Tracker records the weight you type and does arithmetic on it. That is the whole app. It does not give health, diet, fitness or medical advice. It will not suggest a target weight, recommend a rate, or tell you any number is good or bad — your goal is yours to set, and gaining and maintaining are treated exactly like losing. For guidance about your weight, talk to a qualified healthcare professional. BMI, when you enter a height, is a bare number with the note that BMI is a screening measure, not a diagnosis.

WHO IT'S FOR
Anyone who wants a simple weight log without a calorie database, a social feed, or an account: people tracking a long slow change, people holding steady, people gaining on purpose, and anyone who just wants to know whether this month is different from last month.
