“The identity week assumed more SQL comfort than I had. I still finished with a retention view our iOS lead would actually defend.”
Priya N., product analytics, Leeds
Worplesdon · App Analytics atelier
A ledger for what the product actually did.
Most mobile dashboards report motion. Broker Kernelhub trains product people to report behaviour: named events, honest cohorts, and the few charts a Monday meeting can survive.
Founded for United Kingdom product teams who are tired of DAU theatre. One programme is taught in depth; the rest exist to support it.
Heard after the work
Not a chorus. Three different desks.
★★★★☆
“Stopped treating ‘session start’ as a business event. Painful, then quieter dashboards.”
Platform note · 4/5 · Cohort Signal Studio
We had been mixing calendar months with rolling 28-day windows. The studio’s ledger template made the mismatch visible in a single Friday export.

Flagship
Cohort Signal Studio
An 11-week atelier on event taxonomy, identity stitching, and the family of retention curves that lie when you let a vendor pick the window. Taught by Meredith Ainsworth from live UK app datasets, not toy CSVs.
Informational fee from £1,240. No payment is taken on this site.
What we insist on
App Analytics without costume jewellery.
Name the verb
If the event name cannot be acted on a stage, it does not belong in production. We drill taxonomy until “button_click_12” is embarrassing.
Pick a window in public
Cohort math is a policy choice. Kernelhub makes the window, the clock, and the exclusion rules visible to engineering and marketing together.
Keep a weekly ledger
Dashboards rot. A dated Signal Ledger — five numbers, one caveat — is the artefact alumni still open six months later.
