Just record your weight each day (or as often as you like). The app uses some fancy math to smooth out normal day-to-day fluctuations and estimate your overall trend.
I used to track my weight in a spreadsheet. After experimenting with different ways to average out daily noise, I landed on a combination of formulas that gave a clean trend without hiding real change.
I built Yes Weigh so I wouldn't have to deal with that spreadsheet anymore. Then I figured others might find it useful too.
No problem. You can't fill in past days, but Yes Weigh estimates missing entries so the trend line stays smooth.
Not long. After about 10 days of entries, you'll start to see your rate-of-change gauge, along with a short prediction on the chart showing where your trend looks to be headed over the next couple of days.
The bar shows how fast your weight is changing each week.
The center means no change. Fill to the left means losing weight. Fill to the right means gaining weight.
The dotted arrow shows where your rate appears to be heading. If your pace has been steady, no arrow appears.
The scale is relative to your own history, so the bar fills more as your current rate approaches your personal fastest change.
You're losing about 1.2 lbs per week at a consistent pace.
Your rate of loss is accelerating. You're losing faster than last week.
Your rate of loss is slowing. You may lose a little less next week.
You're gaining about 0.6 lbs per week, and the pace appears to be increasing.
Yes Weigh takes a rolling median of your last few days of weigh-ins — so a single odd day doesn't skew things, but a real multi-day shift still comes through quickly — then runs a linear regression on that to estimate the trend. Missing values are estimated automatically so the chart stays readable even when you don't log every day.
Any unit works, as long as you stay consistent.
Yes Weigh is intentionally simple. If you want something more fully featured: Happy Scale is a subscription-based mobile app with more advanced features. TrendWeight is a lightweight app based on the Hacker's Diet method that syncs with smart scales.
Your weight entries are stored privately in a Supabase database and sent over an encrypted connection. Nothing else is collected.
This is a free hobby project, so support is limited. But feel free to email help@yes-weigh.com and I'll do my best to respond.
This is a dead simple weight tracking app. No goals, points, streaks, bells, whistles, or subscriptions.
Just enter your weight each day and the app will give you an estimate of your current weight along with trends about how your weight is changing over time.
The more consistently you record, the more accurate your results. That said, record as often or as sporadically as you like — the math under the hood will do its best either way!
