For a short, focused push — a cut, a bulk, a deadline. About $103 a year if you stay, and we'd rather show you that math than hide it.
LOSE WEIGHT
Today can be up while the trend is down.
A single weigh-in can reflect food, fluid, timing, and ordinary variation. Trendline keeps the longer direction in view.
The useful question is sustained direction
Daily weight is real, but it is not the whole story. Trendline organizes repeated readings into a slower-moving interpretation so one morning does not get to rewrite the plan.
Progress without false precision
The app can describe change supported by your readings. It does not promise a future result, prescribe a deficit, or claim to know exactly which tissue changed.
Plan for what comes next
A cut is a phase. Maintenance is another skill, not an empty space after the “real” work. Trendline is designed to make that handoff visible.
Feel it with your own numbers first: the free Goal Timeline turns a target into a realistic arrival window, and the Weight Trend Calculator shows the direction under your daily readings.
THE APP UP CLOSE
A cut, read honestly.
This is the real dashboard during a losing phase — the app's own sample readings, not a mockup. What it says, and what it refuses to say.
The headline
“Steady loss at level fat share.” The app leads with the sustained direction, then keeps the body-fat estimate in context rather than assigning meaning to one morning’s reading.
The two three-month tiles
Weight is down 4.5 lb while the body-fat estimate is down 0.7%. The two measurements stay distinct and visible together.
The milestone
The Weight tile marks a recent low, while the goal card keeps the 180 lb target and 16.2 lb remaining in view. The moment matters without replacing the longer trend.
A real screen from the app, running fictional sample readings. No person’s health record is shown.
