Progress tracker
A date and a weight, as often as you like. The page keeps the log in your browser, draws the 7-day average and the trend, and tells you whether the body is following the plan.
Showing an example of six weigh-ins. Add your first one and it is replaced.
Down 0.7 kg a week on the trend line
The trend line is a least-squares fit through every weigh-in. Single days are noise (water, salt, a late meal); the line and the 7-day average are what to read. Weigh yourself the same way each time: morning, after the bathroom, before food.
Plan says, body says
No plan saved yet. Build one in the cutting timeline; it reads these weigh-ins back.

The plate is what changes the line
Same base all week, one sachet at the table. The numbers do not move.
Build a plateHow this is calculated
7-day average: for each weigh-in, the mean of all weigh-ins in the seven days ending on that date. Trend: least-squares slope through every logged weight, expressed per week.
Plan says / body says: the planned pace is the saved cutting timeline's total loss divided by its weeks; the measured pace is the trend slope. Ratio within 0.75 to 1.25 is reported as on plan. Waist and body fat are logged but not used in the arithmetic.
- Least-squares regression (ordinary), any statistics text; no external data used.
- Cutting timeline tool on this site - source of the planned pace
Straight answers
Where is my data stored?+
In your browser's local storage on this device. Nothing is sent to us.
How often should I weigh?+
Daily if it does not bother you, three times a week if it does. Same conditions each time: morning, after the bathroom, before food and drink. Consistency matters more than frequency.
Why read the 7-day average and not the daily number?+
Daily weight swings a kilo or two with water, glycogen, sodium and the timing of meals. The 7-day average smooths that out, and the trend line through all weigh-ins is the most honest single number for pace.
What does plan says / body says mean?+
If you built a cutting timeline in this browser, the tracker compares its planned weekly pace with the measured trend over your weigh-ins. Within 25% either way counts as on plan.
