About

Simple Weight Log

Features
Read full description

Simple Weight Log lets you record your daily weight in about three seconds. No judgment, no pressure, no lectures — just your numbers, shown clearly. ■ A 3-second daily routine The app opens straight to a number pad with your last weight already filled in. Adjust with the +0.1 / -0.1 buttons and save — done. One entry per day; saving again on the same day simply overwrites it. No account, no setup. ■ Trend chart with moving averages View your weight as a line chart over 1 month, 3 months, 1 year, or all time. Overlay 7-day and 30-day moving averages to smooth out day-to-day fluctuations (like water weight) and see the gentle underlying trend. ■ Day-to-day change, streak, and BMI The home screen shows the change from the previous day and your recording streak. Set your height to see your BMI and a reference standard weight (based on BMI 22) — shown as reference values only. ■ A goal, expressed in numbers Set a target weight and date to see the required pace (kg per week), your progress, and a projection based on your pace so far. It works the same whether your goal is to lose or to gain. If the pace exceeds 1% of your body weight per week, the app shows a gentle caution note. ■ Home Screen and Lock Screen widgets Your latest weight and 7-day change on Home Screen widgets (small and medium) and Lock Screen widgets (circular and rectangular) — visible without opening the app. ■ CSV export Export all your entries as a CSV file (date, weight_kg). Your data is always yours to take. ■ Your weight stays on your device All entries are stored on your device. No account is required, and your weight data is never uploaded. There is no HealthKit or iCloud sync. ■ Honest about its limits - Units: kilograms (kg) only. Pounds are not supported. - The daily boundary is based on Japan Standard Time (JST). - This app is not a medical device. BMI and other figures are reference information, not medical advice. It does not promise weight loss or health outcomes — it records your weight and shows it clearly, nothing more. [Ads and purchase] Every feature is available to use. A banner ad is shown at the bottom of the screen; a one-time "Remove Ads" purchase hides the banner (no subscription, no auto-renewal). Showing ads requires a network connection, but your weight data is never sent. Privacy policy: https://honki.ai/simple-weight-log/privacy.html
