Log a weigh-in

Weight is the single most important input for the trend line, the ETA-to-goal estimate, and most pattern insights involving body composition. One number per day is enough.

How to log

  1. Tap Quick Log → Measurement (or weight section on the Log page).
  2. Enter the weight in your unit (lbs or kg, set in Profile → App → Units).
  3. Date defaults to today. Pick a different date for back-dating.
  4. Tap Save.

That's it. Most users do this first thing in the morning.

When and how to weigh

For the trend line to read clean:

  • Same time of day — first thing in the morning is most consistent.
  • After bathroom, before food / drink.
  • Same scale, same surface — moving the scale to a different floor changes the reading.
  • No clothes or consistent clothes — anything is fine, just be consistent.

You don't need to weigh every day. Three to five times a week produces a usable trend. Daily is best.

Backdating

Pick any past date in the date picker, log normally. The trend line and stat grid recompute.

What the dashboard shows

After a few entries, the dashboard's body section displays:

  • Daily weight dots — your raw entries.
  • Trend line — a smoothed regression that filters daily noise.
  • Goal line — horizontal line at your target weight.

The trend matters more than the dots. Daily weight bounces ±1–3 lb on water, glycogen, sodium, sleep, cycle phase, and digestion. The trend line cuts through that.

Stat grid

Below the chart, eight numbers summarize your progress:

StatWhat it is
CurrentMost recent entry.
Total changeDifference from your first logged weight.
BMIBody Mass Index, computed from your height and current weight.
% changeTotal change as a percentage of starting weight.
Weekly averageTrend-line value at today (smoothed).
TrendSlope of the trend line, in lb/week or kg/week.
To goalDistance from current to goal weight.
ETAWeeks until you reach your goal at the current trend rate. See Trend & ETA.

If you don't have a goal set, the goal-related stats hide.

Common questions

"My weight bounces 3 lb in a single day. Should I worry?" No. That's normal. Daily fluctuation comes from water (1–4 lb), glycogen (1–2 lb when carb intake changes), sodium (1–2 lb temporarily), and digestive contents. Watch the trend.

"Why is the trend line flat when I'm eating in a deficit?" Possible causes, in order of likelihood:

  1. The deficit is smaller than you think (TDEE estimates can be off ±20%).
  2. You're early — give it 2–3 weeks for the trend to stabilize.
  3. You're recomp-ing — losing fat and gaining muscle. Check waist or photos for confirmation.
  4. Water retention from new exercise, sodium, or stress.

"Should I track weight and waist together?" Yes if you can. Weight without waist misses recomp. Waist without weight misses water shifts. The dashboard's multi-series chart can plot both on the same time axis.

"What unit does the app use?" You pick lbs or kg in Profile. The setting is global.

The weigh-in feeds:

  • The trend line (regression) and ETA projection.
  • Per-day BMI in the stat grid.
  • The rolling 7-day budget uses your current weight when recomputing TDEE if you've changed weight significantly since setup.
  • Pattern insights — weight is one of the highest-frequency series in the data, so it correlates well against doses, calories, and macros.
