## What is Spoketrue?

Spoketrue is a private bicycle wheel-build desk for spoke geometry, measured tension, truing checkpoints, and service history.

Calculate left and right spoke length from rim and hub dimensions, keep component and lacing records, enter your own manufacturer target and calibrated meter readings, visualize side variation and balance, track dish, lateral, and radial checkpoints, and export a local build card.

KEY FEATURES
- Left and right spoke-length geometry
- User-entered target and tension-reading log
- Side balance and variation visualization
- Rim, hub, spoke, lacing, truing, and service records
- Searchable 90-plate offline wheel guide
- Local PDF build card
- No account, ads, analytics, tracking, subscription, or network requirement

Spoketrue does not prescribe safe tension or certify a wheel. Verify dimensions, calculations, calibration, component limits, and the finished build with authoritative sources.


## Version history (last 2 releases)

### 2.0 — 2026-08-24

This release rebuilds Spoketrue around real wheel-shop workflows:

- True left/right spoke-length geometry: separate flange dimensions per side, bracing angles, predicted tension share, rounding to stock sizes, and validation warnings.
- The tension log now draws the wheel as it actually measures: a polar chart of your meter readings, per-side statistics, evenness against each side's own average, and measured vs. predicted side balance.
- Wheel records collect components, saved geometry, tension sessions, dish/lateral/radial truing checkpoints, and service notes - and export as a one-page build card PDF.
- The 90-plate reference guide is now searchable, with category filters.
- Notes you saved in 1.x are kept and imported into a wheel record automatically.

As always: fully offline, no account, no tracking, and Spoketrue never prescribes a tension - targets come from your component maker.

### 1.0 — 2026-07-22

No release notes.
