An editorial weight tracking experience — built with science, designed with empathy, protected by privacy.
Your daily weight is noisy — water, sodium, hormones, and timing create fluctuations that mask the real signal. Filiz uses an Exponentially Weighted Moving Average to reveal the true trend beneath the noise.
Pre-seeded horizontal ruler with yesterday's value as anchor. Swipe to adjust — haptic feedback on every 0.1 kg tick. Numpad fallback for big changes or accessibility.
"This number is today's. Tomorrow it will change. That's normal."
From sodium spikes to menstrual cycles, from new exercise routines to travel disruptions — Filiz has an explanation card for the most common weight fluctuation causes.
Your body stores glycogen + water in recovering muscles. This is repair, not weight gain.
This is metabolic adaptation — your body is adjusting to a new baseline. Completely normal.
Filiz supports 11 GLP-1 medications including pipeline drugs. Track your dose, see estimated plasma levels, rotate injection sites, and compare your progress to clinical trial benchmarks.
