Track your weight and see what's really happening — not the daily noise.
Momentum uses trend smoothing to cut through the natural fluctuations that
make daily weigh-ins misleading. Water retention, meal timing, and other
factors can swing your weight by several pounds in a single day. Momentum
shows you the real trend underneath, so you always know whether you're
actually making progress.
SET A GOAL, TRACK YOUR PROGRESS
Set a target weight for losing, gaining, or maintaining. Watch your progress
with a visual progress bar, and get a predicted goal date based on your
current pace. If your weight stalls or moves the wrong direction, Momentum
tells you clearly with trends.
MAINTAIN WITH CONFIDENCE
Reached your goal? Switch to maintain mode. Set a comfortable range, and
Momentum tracks your streak of days within it. You'll always know where you
stand.
CHARTS THAT TELL A STORY
A smooth trend line and weekly bar chart show your trajectory over 7 days,
30 days, 90 days, a year, or all time. Tap any point for details. Toggle
between your actual weigh-ins and the smoothed estimate.
KNOW YOUR BMI
Enter your height once, and Momentum calculates your BMI from your trend
weight. See your category, your healthy weight range, and how it changes
over time.
