Your weight jumps around every day. Your progress doesn't.
The scale can swing 2–6 lbs overnight — water, salt, hormones. logseen smooths that noise into your real trend, so one heavy morning never derails you again.
The Tuesday problem
You know that Tuesday morning.
You've been careful all week. You step on the scale — up 1.8 lbs. You didn't gain 1.8 lbs of fat overnight; that's water, salt, and timing. But it still ruins your morning, and it's the #1 reason people quit. logseen was built for exactly that moment.
How it works
One number a day. That's the whole job.
Weigh in each morning
Type one number. Two seconds, done.
We smooth the noise
A proven moving-average method turns scattered mornings into one honest line.
Watch the real line
Trend, forecast to your goal date, milestone progress.
The trend line
The dots are your mornings. The line is the truth.
Every weigh-in lands as a faint dot. The mint line running through them is your real direction — watch the noise flatten in front of you.
The talk-down
When the scale spikes, we talk you down with math.
"Up 0.6 lb today — your trend is still falling." Not a platitude: computed from your own data, shown exactly when the number stings.
The forecast
Progress you can put on a calendar.
At your trend's real pace, logseen projects your goal date — "around Oct 12" — and tracks how far you've come. No wishful math: if the trend isn't clear yet, it says so.
Two seconds tomorrow morning. That's all it takes.

The difference
Not another calorie counter.
Most weight apps hand you a second job: log every meal, scan every barcode, track every workout. That's why most people quit them. logseen deliberately does none of it.

FAQ
Questions, answered.
Is logseen free?
Yes: logging and your trend line are free, no limits on entries or history. Premium adds progress photos, automatic weight import from Apple Health and Health Connect, and multi-device sync — as a subscription or a one-time lifetime purchase.
Why does my weight jump around so much?
Water retention, sodium, glycogen, hormones, and timing move the scale 2–6 lbs day to day. It isn't fat — fat changes far more slowly. That daily noise is exactly what logseen filters out.
How is the trend calculated?
An exponentially-weighted moving average over your daily weigh-ins — the method trend-weighing tools have used for decades. Recent days count more, so it reacts to real change within about two weeks.
What if I skip days?
Nothing breaks. The trend continues from the data you have. No streaks, no guilt.
Pounds or kilograms?
Both — logseen follows your device's region and you can switch anytime.
Is my data private?
It lives on your device first and syncs encrypted. We don't sell data, show ads, or use third-party trackers. See the privacy policy.
