Name every onboarding step before you measure it
Vague labels like “setup done” hide drop-off. A short naming discipline makes mobile onboarding funnel measurement usable for product decisions.
Mobile onboarding funnel measurement only helps when each step means the same thing to product, engineering, and marketing. Many teams fire an event called “completed” that actually marks permission grants, profile saves, or first content views interchangeably.
Start with a table: screen name, user intent, completion rule, and the single event name that will represent it. Keep completion rules observable in the app — for example, “account credentials accepted” rather than “user feels ready.”
When two steps share one event, split them. When one step fires three events, collapse to the one your funnel chart will use. Document excluded paths such as skip buttons so they do not quietly inflate completion.
Hand the table to whoever owns instrumentation with a change log. The first week of cleaner names usually surfaces false drop-off that was really mislabelled success.
