This is a copy of what the app just sent to Firebase, newest first. On a real job you don't have this panel: you'd use DebugView. Try to check the events there too (see the last tab).

Click an event to see its parameters.

Measurement plan = the rulebook. It lists every event and parameter the app must send. Your job is to check the app sends exactly this.

Event	When it fires	Parameters
`screen_view`	Every screen	`firebase_screen` (lowercase, e.g. `card_activated`), `firebase_screen_class`
`sign_up_start`	Tap "Open an account"	–
`onboarding_step`	Each onboarding step completed	`step_name`
`sign_up`	Account opened screen, once	`method` = "email"
`login`	Successful login	`method` = "passcode"
`experience_impression`	Home screen, when the banner shows	`exp_variant_string` = "home-banner:A" or "home-banner:B"
`transfer_start`	Tap "Send money"	–
`transfer_complete`	"Money sent" screen	`value` (number), `currency` = "EUR"
`card_activated`	Card activated screen	`card_type` = "debit"
User properties and ID
`login_status`	Updated at app start, login, sign-up and logout	"logged_in" / "logged_out"
`user_id`	Set after login or sign-up, cleared on logout	internal ID, e.g. "C-84721"

How to play: keep "Inject tracking bugs" on, go through every flow (sign-up, login, home banner, transfer, card). Each card is a complaint from a colleague. Reproduce it in the event log or DebugView, then pick the cause.

DebugView shows events from devices in debug mode, live, within a few seconds. This app sends debug_mode: true with every event, so you'll see it there.

Open console.firebase.google.com → project uli-practice.
Left menu: Analytics → DebugView (or in GA4: Admin → DebugView).
Use the app here. After 5–30 seconds your device appears and events show on the timeline.
Click an event to see its parameters. Compare with the measurement plan.
Standard reports (Events, Explorations) fill up after 24–48 hours.

Tip: ad blockers can block analytics. If nothing arrives, pause your ad blocker for this page.
