Weight Tracker
Losing weight is simple in theory, but staying on track is hard when the scale swings up and down from one day to the next. A weight tracker takes the guesswork out of the process by turning scattered weigh-ins into a clear trend line you can actually read. This free weight tracker lets you log your weight each day in pounds or kilograms, set a start weight and a goal weight, and watch the overall direction emerge through the daily noise.
Most people quit a diet not because it isn't working, but because a single up-tick on the scale feels like failure. The truth is daily weight fluctuates by several pounds thanks to water, sodium, carbs, hormones, and bathroom habits - none of which reflect fat loss or gain. By charting your entries over weeks, this tracker shows you the trend that matters instead of the number that doesn't.

How it works
1
Log your weight
Pick a date and enter today's weight in pounds or kilograms. Entries are saved automatically in your browser.
2
Set your goal
Add a start weight and goal weight. The chart draws a dashed goal line and the sidebar shows your remaining distance.
3
Watch the trend
The line chart connects your entries so you can see the overall direction, not the daily noise. Compare your latest weight to the dashed goal line to see exactly where you stand.
Understanding your result
A healthy, sustainable rate of weight loss is about 0.5 to 1 lb per week (roughly 0.25 to 0.5 kg). That pace is slow enough to preserve muscle, avoid nutrient shortfalls, and keep your metabolism steady, and it's far more likely to stay off than weight lost quickly. Losing faster than 2 lb a week usually means shedding water and muscle along with fat, and raises the risk of rebound gain.
Your day-to-day weight will swing up and down even when you're doing everything right. A salty restaurant meal can add 2 to 4 lb of water overnight; a hard workout, hormones, or not sleeping well can do the same. None of that is fat. Expect the scale to move in a zigzag, not a straight line - some weeks you'll see a whoosh of loss, others a flat or up reading.
That's why the trend is what counts, not any single weigh-in. If the line over two to four weeks is drifting down toward your goal line, you're on track. Compare your latest entry to where you started and to the dashed goal line, and let the overall direction - not yesterday's number - decide whether to adjust your calories.
Frequently Asked Questions
How often should I weigh myself?
Most people do well weighing in daily under consistent conditions - same time of day, ideally first thing in the morning after using the bathroom. Daily weights fluctuate from water, sodium, and carbs, so focus on the weekly trend rather than any single day. This tracker charts your trend so day-to-day noise is easier to ignore.
Should I track my weight in pounds or kilograms?
Either works - pick whichever your scale uses. This tracker lets you toggle between lb and kg at any time, and all entries are stored in the unit you logged them in. Your goal weight and start weight travel with the share link so you can bookmark your setup.
Is my weight data private?
Yes. Every entry is saved only in your own browser using localStorage - nothing is uploaded to a server. Clearing your browser storage will remove the data, so export or copy the share link if you want to preserve your goal settings.
How is the remaining-to-goal calculated?
It is the difference between your most recent logged weight and your goal weight. Set a goal weight in the sidebar and the tracker shows how far you have left to go, along with total change since your first entry.
Why did I gain weight overnight?
An overnight jump is almost never fat - you'd need to eat roughly 3,500 extra calories to gain a single pound of it. The usual culprits are water retention from a salty or high-carb meal, a tough workout that inflames muscles, hormones, dehydration, constipation, or poor sleep. Weigh again under the same conditions for a few days and the number typically settles back down.
What's a healthy weight loss rate?
Aim for 0.5 to 1 lb per week (about 0.25 to 0.5 kg), which corresponds to a daily calorie deficit of roughly 250 to 500 calories. Faster loss tends to shed water and muscle and comes back more easily. If you have a lot to lose, the higher end is fine; if you're already lean, slower is better to protect muscle and metabolism.
What if the scale isn't moving?
First, give it two to three weeks - water can mask fat loss for that long. Then double-check your portion sizes and tracking, since people routinely underestimate intake by 20% or more. If you're genuinely stuck, a small 100 to 200 calorie cut or a bit more daily movement usually gets things moving again. Re-calculate your needs too, since a smaller body burns fewer calories.
