## What is Wheel Builder?

Wheel Builder is a native bicycle wheel spoke length calculator for builders who want quick, local access to hub, rim, and lacing measurements.

Calculate left and right spoke lengths from ERD, flange diameter, center-to-flange distance, spoke count, left/right cross pattern, rim offset, and spoke hole diameter. Save common hubs and rims as presets, store complete wheel builds, and import or export JSON backups when you want to move data between devices.

Features:

- Left and right spoke length calculation
- Hub and rim preset library
- Saved wheel builds with notes
- Rounding options for order lengths
- Rim offset and spoke hole diameter adjustments
- Local JSON import and export
- Offline-first native app experience
- No account, ads, analytics, or tracking

Always verify manufacturer hub and rim specifications before ordering spokes.
