Flight shugyō, made local.

A small companion for the Japanese aviation community — now a native SwiftUI app for iPhone and iPad, alongside the web app at flightchain.app. Built in response to changes in a major airline's elite-tier program: a quiet experiment in carrying the rhythm of “shugyō,” the frequent-flyer pilgrimage, into the living room.
