See the trend. Keep the ritual gentle. Shell & Scale is a focused daily weight tracker built to make check-ins feel clear, calm, and satisfying. Log one number, understand how it changes over time, and let a curious sea turtle add a little personality—without turning your health data into a game you can fail. WEIGHT TRACKING THAT STAYS CLEAR • Record in pounds or kilograms • Review 7-day, 30-day, 90-day, or all-time trends • Inspect individual entries on an interactive chart • Edit or delete any check-in • Explore your history with a check-in calendar • Export your complete history as CSV DESIGNED FOR REAL DAILY FLUCTUATIONS A single reading is context, not a verdict. Shell & Scale emphasizes the longer trend and uses neutral language whether your weight moves up, down, or stays steady. CHOOSE HOW MUCH YOU SEE Exact mode shows readings and changes. Gentle mode keeps the trend central. Blind mode lets you log without seeing numbers or direction. A COMPANION, NOT A COACH Name your turtle and reveal small reactions, keepsakes, and environments as you keep checking in.
