Currently when you go to Progress > Body Measurements there is no way to view exact dates for previous weight entries. A missed opportunity imo, adding some decent charts for body stats would add a lot of value to a tracking app for those in a calorie deficit and tracking weight loss over a period of time. Other apps have this feature and it seems fairly simple to achieve. Also, I don't think you should have to go to update your body measurements to access the chart, just make it easily accessible for users to reference.
