How forecasting works.
Trend smoothing
We model your weight as a moving trend, filtering daily water-weight swings so you see signal, not noise.
Adaptive pace
Your loss rate is recalculated rolling-window — the forecast adapts as your body and habits change.
Calorie balance
Combining intake, output, and trend, we project realistic dates and flag when you're drifting off pace.
Plateau detection
When your trend flattens, WeightLytic alerts you early with concrete, personalized adjustments.
Goal flexibility
Change your goal anytime. The forecast recalculates instantly with no data loss.
Honest confidence
We show forecast ranges — not false precision. You always know how certain (or uncertain) we are.
Common forecasting questions.
When will I get my first forecast?
Typically within about a week of consistent weight logging. The forecasting engine needs a short run of data points to establish your trend before it can project a goal date.
How accurate is the forecast?
Accuracy improves the more consistently you log. Rather than a single false-precise date, WeightLytic shows a confidence range, so you always know how certain the projection is.
Does the forecast update over time?
Yes. It recalculates as you log — your projected goal date adapts to changes in your pace, your habits and your goal, with no data loss when you adjust your target.
What if I hit a plateau?
When your weight trend flattens, WeightLytic flags it early and suggests concrete adjustments, so a stall becomes information rather than a motivation killer.
Can I try forecasting before the app launches?
Yes. The free Forecast Calculator gives you a rough goal-date estimate from a few numbers right now; the full in-app forecast updates daily once WeightLytic launches.
