About this app

Weight Tracker is a simple weight log that shows the trend, not just the number. Type the weight your scale shows, and see your real trend under the daily ups and downs, how much it moved this week, and the date you reach your goal at your current pace. Your data stays on your phone and exports any time.

The scale jumps half a kilo overnight with water and salt. This body weight tracker smooths those jumps into one calm trend line, so you can see whether you are really moving, week by week.

WHAT YOU CAN DO
• Log a weigh-in in seconds: your last weight is already filled in, tap minus or plus and save
• Kilograms, pounds, or stones and pounds, switch any time
• See your trend: weight tracker with trend line, your daily weigh-ins as dots behind it, over 30 days, 90 days, a year or all time
• Set a goal with any start date, past or future, and see the projected date you reach it
• A weight loss tracker that also works for weight gain or maintenance: the goal goes both ways
• BMI calculator built in: add your height to see the BMI of your trend weight (you can hide it)
• Optional body fat field and a note on each weigh-in
• Daily weight tracker reminder: a weigh in reminder each morning at your time, back after a restart
• Up to three people: keep a weight diary for a partner or a family member too

YOUR DATA IS YOURS
• Export a CSV file any time, for any period
• Weight tracker PDF export: a report with the trend, the range, a chart and every weigh-in
• Import a CSV from your old weight log app: dates and weights, kilograms or pounds
• Save a backup file and restore it on a new phone
• Weigh-ins, heights, goals and names are stored on your device only. There is no account. The app uses Firebase Analytics and Crashlytics for anonymous usage and crash reports, and Google AdMob for ads; no weight, height, goal or name is ever sent with them.

MADE TO OPEN EVERY MORNING
• One big button, one number, done in ten seconds
• Light and dark themes
• 19 languages

HOW TO USE IT
Weigh yourself at the same time each morning, after waking, on the same scale, and log it. After a week the trend settles; after two weeks the goal date appears.

IMPORTANT
Weight Tracker is a personal log for general wellness, not a medical device and not medical advice. It does not measure your weight: it records the values you type from your own scale. BMI is a general indicator and does not apply to everyone. Talk to a health professional before big changes to your weight or your diet.
