Just Weight makes weight tracking simple. Logging takes about five seconds. Tap, spin the wheel to your weight, and save. The History tab charts your weight by week, month, or year. If you weigh in on a set day each week, you can show only those days to smooth out daily ups and downs. Working toward a number, whether losing or gaining? Set a plan with a goal and a target date. The Plan tab shows whether you're ahead or behind, and how much change per week it takes to get there. Works in lbs or kg. Entries are backed up to your account, so switching phones doesn't mean starting over.
