PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. Step on the scale, log one number, and see the truth: not today's water-weight blip, but the line your body is actually following. This is a weight diary built around the 7-day moving average — the same idea trend-tracking veterans swear by — so a salty dinner or a long flight never looks like failure again. Most weight apps bury the scale under calorie counting, meal photos and macros. This one does the opposite: one number a day, a chart that tells the truth, and a goal that points wherever YOU are going — down, up, or holding steady. Everything works in kg or lb, and nothing requires an account. WHAT YOU GET • Your real trend at a glance — a 7-day moving-average line drawn through your actual weigh-ins, so daily jitter flattens out and the direction becomes obvious • A goal that works in any direction — losing, gaining, or maintaining, with a projected days-to-goal figure based on the pace you are actually logging • An answer to "how far to go?" the moment you open the app — current weight, target weight, and the exact distance between them on one dashboard • A history you can actually read — Today, Yesterday, every entry with its optional note, filtered to the last 30, 90, 180 days or all time, with weekly low/average/high • A daily weigh-in reminder at the hour you choose, feeding a day-streak counter that makes the habit stick • Your numbers on your terms — one tap exports every entry as a CSV you can hand to a coach, a doctor, or your own spreadsheet PERFECT FOR • Anyone losing weight who is tired of panicking over normal daily fluctuation • Hard gainers and athletes tracking a deliberate bulk toward a target date • People in maintenance who just want an early warning when the line starts drifting • Anyone whose doctor said "keep an eye on your weight" and wants a private place to do it WHY NOT JUST USE A SPREADSHEET OR THE HEALTH APP? A spreadsheet shows you a jagged line and leaves the interpretation to you. A general health hub buries weight three menus deep among steps and sleep. This app opens straight to the one question that matters — where is my weight really heading, and how far is the goal — and answers it in two seconds, with a smoothed trend a raw list of numbers can never show. It can also estimate BMI from your height if you want that context, clearly labeled as a screening range, not a diagnosis. PRIVATE BY DEFAULT Your weight history stays in the app's own database on your iPhone. No account, no sign-up, no cloud upload, no tracking. The only way your data leaves the device is when you export the CSV yourself. PREMIUM (PURCHASE REQUIRED) The app runs on a Full Access pass that unlocks everything: unlimited weigh-ins, the trend chart with moving average, goals with projected days-to-goal, streaks, weekly stats, daily reminders and CSV export. Choose a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. Payment is charged to your Apple ID account; subscriptions renew unless cancelled at least 24 hours before the end of the period, and can be managed in your account settings. Weigh in tomorrow morning, log the number, and in a week you will see something no bathroom scale can show you: your line.
