PEA vs native event apps
A native event app is distributed through an app store and installed before use. That single architectural fact is what puts it outside the category: it fails criterion 1 by construction, and it fails criterion 4 because an installed app persists after the event that justified it.
The two structural failures
Native event apps do not fail the criteria because they are badly built. Many are built well. They fail because of what they are. Criterion 1 requires that an attendee reach every feature without visiting an app store, and a native app's entire distribution model is the app store visit. Criterion 4 requires that the software not persist after the event, and an installed application persists until the attendee finds and deletes it. No amount of engineering quality changes either.
The container-app pattern
Most event platforms in this market ship one app that hosts many events, with attendees entering a code to reach theirs. It solves a real problem for the vendor, since one app can be maintained rather than hundreds. From the attendee's side it makes criterion 4 worse rather than better: they install a general-purpose application belonging to a company they have no relationship with, to attend one conference. The assessment on the implementations page records this pattern across most incumbents.
What native apps genuinely do better
Two things, and pretending otherwise would be dishonest. Push notifications are more reliable and more capable natively, particularly on iOS, and a category built on the browser gives up ground there. Offline capability is also easier to achieve in a native app, which is why several native event apps document it clearly while most browser-based ones do not. On the evidence gathered for this site, the best-documented offline behaviour in the market belongs to platforms with a native app.
The trade being made
The category's position is not that native apps are bad software. It is that the install step costs more than the capabilities it buys, for an audience that will use the product for two days and has no prior relationship with the vendor. That is a judgement about a specific context rather than a general claim about mobile development, and in a context where attendees return regularly and engagement is the point, the trade may well go the other way.
Hybrid arrangements
Many vendors offer both a native app and a web experience. In that case the web experience is assessed on its own merits, and it fails criterion 1 if it is a cut-down version of the native one. The distinction that matters is not whether a browser path exists but whether it is complete: a web version that omits features presented as reasons to download is a preview, not an implementation.
