A precise ruler-style value picker for centimeters with a centered indicator, dense major/minor ticks, and a large live numeric readout. Smooth inertial scrolling and step snapping make height/length input fast and accurate—no keyboard needed.

Functionality

• Scrollable ruler track with numbered major ticks and fine minor ticks.

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

• Big live value with cm unit; configurable precision (e.g., 170.0).

• Step size & snap (0.1 / 0.5 / 1.0 cm) for consistent increments.

• Min/Max bounds and clamped selection (e.g., 100–220 cm).

• Natural inertial scrolling with gentle deceleration.

• Tap/drag gestures and optional keyboard fine-tuning.

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

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

• RTL & i18n: reversible direction and localized number formats.

• Accessibility: high-contrast ticks, large value text, semantic labels.

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

• Light/Dark support with subtle shadows for depth.

Great for: height pickers, garment sizing, fitness profiles, medical/measurement forms, budgets/limits (with custom units), and any UI that needs a precise, touch-friendly numeric input.
