Nice for storing trip details, but failed to show gate number at KIX. Just showed a question mark until and after departure, so had to rely on screens at airport. Also failed to report the delay to the flight. Worked OK on return trip from Hong Kong. Sent 2 emails to support and never received a response. Update: doesnt reflect correct (changed) flight times as advised by airline (e.g. Hiroshima to Seoul). Showed wrong terminal for a flight from Taipei. Developer doesnt reply to e-mails.
