You can easily view your history with the app, and you can delete data if you want to. All the measurement data are yours; you have full control of your own data. (1) Tap on the “Trends” icon (bottom center of the main screen), you will be able to access your measurement history. You can configure your charts by week, month, or by year. You can also choose to show data by AM, PM or All Day. This is a useful feature to eliminate the impact of your body weight fluctuation. (2) Tap on the “Calendar” icon (upper right corner, a clock alike icon), or click anywhere on the chart to view details, a calendar will appear, with measurement data shown under the calendar.
