A precise ruler-style value picker with a centered indicator, dense major/minor tick marks, and a large live numeric readout with units (e.g., kg). Smooth inertial scrolling and step snapping make it ideal for inputs that need accuracy without a full keyboard.

Functionality

• Scrollable ruler track with major (numbered) and minor ticks.

• Center indicator line: align ticks under the marker to select the value.

• Large live value with unit label (kg, cm, %, etc.), configurable precision.

• Step size & snapping (e.g., 0.1 / 0.5 / 1.0) for consistent increments.

• Min/Max bounds with soft limits and clamped selection.

• Inertial scrolling with gentle deceleration for natural feel.

• Tap/drag gestures and keyboard support (optional) for fine tuning.

• Haptics/ripple feedback on step changes (optional).

• Theming: accent color, tick density/length, typography, indicator style.

• RTL & localization: reversible direction, localized number format.

• Accessibility: high-contrast ticks, readable type, semantic value announcements.

• Data-ready: bind to Firestore/Supabase/REST/local state; onChange / onEnd.

• Light/Dark support with subtle shadows for depth.

• Use cases: weight/height, dosage, budgets, percentages, scores, timers.

Great for: health forms, fitness apps, calculators, booking limits, and any UI that needs a precise yet touch-friendly numeric input.
