Monthly readout; scorecard stays free

$149 / month

Free move list: email when this shop's stamp changes. Watch ($149/mo) is the monthly readout beside it — different product. Payment never touches the grade.

Told when a model starts or stops naming them
Machine-readability changes re-checked each edition
Payment never touches the grade

Watch — $149/mo

$149 a month against a four-figure job. If one readout helps you win back a single job a year — or hold one you were about to lose to a shop the assistants like better — it has paid for itself. The scorecard stays free either way.

This scorecard is free and it is not for sale. We do not sell the fix, and no payment moves this number — not from this business, not from whoever markets it. Send corrections with evidence to watch@lodestarindex.com.
