Field Ledger for Product Signals
Name every metric once, then carry it across store, web, and in-app event streams without renaming it in the slide title.
Course pageStudio notes from Ashby De La Launde
One reporting week, three surfaces, fewer arguments in the stand-up.
Workspace Anchorcore trains product and data desks to write Cross-Platform App Reporting that survives store delays, SDK drift, and the habit of screenshotting dashboards into Slack. The work is paper-first: definitions, then queries, then the narrative you can defend on a Thursday.

What people actually said after the first cohort
All desk notes“Field Ledger forced us to stop treating Android retention as a cousin of iOS. The workbook is fussy, which is the point.”
“I still dislike writing the limitation line in every weekly pack. I now do it because Storefront Discrepancy Lab made the cost of skipping it obvious.”

A reporting voice that does not collapse when a platform lags
Most teams already have tools. They lack a shared sentence for “this number is late,” “this number is sampled,” and “this number is a different user identity.” Those sentences are the studio’s output.
- A metric passportEach measure gets an owner, a grain, and a platform caveat you can paste into any weekly note.
- A discrepancy ritualYou practise a fifteen-minute check before publishing, not an autopsy after the exec thread.
- A narrative spineThe pack follows cause, coverage, and next experiment — not a gallery of charts.

When funnels disagree on purpose
A checkout that is three steps on iOS and five on web is not a tracking bug. It is a product fact.
