Name the verb, not the screen
If your event is called HomeViewed, you have described a layout. We teach you to name the human action the product hoped for, and to refuse events that only exist because a designer shipped a new tab.
App Analytics
Most teams drown in charts. We teach the few signals that change the product.
Retention is a conversation with people who already installed you. Learn to hear it without inventing a story.Open the course list
From the studio
A short letter, not a manifesto
Dev Pulsebase exists because too many App Analytics programmes begin with a vendor login and end with a wall of dashboards nobody trusts. We start the other way: name the events a product actually deserves, then decide which charts are allowed in the room.
Our rooms are small. You bring an app you already ship — or sit beside the person who does. We work in Greenwich Mean Time, with recordings for those who cannot join live. The work is slow on purpose. A clean event dictionary beats a decorative North Star every time.

Retention Signal Architecture
The autumn studio walks a product team from a noisy event stream to a weekly readout a sceptical founder will actually sit through. Modules cover naming, activation windows, cohort honesty, and revenue events that survive store-kit changes.
Informational fee for a Studio Seat: £1,840. Seats are limited because critique does not scale.

What we insist on
Three essays we keep handing back
Activation has a clock
Day-1 conversion is not a personality test. We map the actual opening rhythm of your app — lunch-break banking, evening language drills, weekend DIY — and set windows that match those hours, not Mixpanel’s default.
A weekly readout, not a museum
Friday should produce one page: what moved, what we distrust, what we will change in the next build. If a chart cannot survive that page, it does not belong in the studio.
Voices from recent rooms
They argued with the homework. That was the point.
The taxonomy session in Retention Signal Architecture stopped our Android and iOS events from drifting apart. The instrumentation homework ate two evenings I did not have; I still finished, because the drift was costing us more than the evenings.
I came in convinced DAU was our north. After the module on vanity week-0 spikes I took DAU off the all-hands slide. Our CEO disliked that for a fortnight. Then trial-to-paid stopped looking mysterious.
Short note: the Signal Atlas naming rules are now in our pull-request template. That is the whole review.
