I'm puzzled by the following time picker:
Proposing only the even hours is fine, but then why bother to propose minutes as well? It's strange to let the user choose 10.05
but not 11:00
.
If that matters, this picker is part of a mobile app selling train tickets, and selecting 10:00
will display all trains departing from a specific station after 10am.
This picker has been like that for about one year, so I suppose it's a deliberate choice. Maybe this design has been proven to be effective? If so I'd be curious to have some references.
