★★★★☆ 効果アリです。素晴らしい! ただ私の場合、乗り物から降りたあとに環境が変わるせいか、多少気分が悪くなります。 Using the app helps to reduce discomfort while on the bus, but it still gives me mild motion sickness for a while after I get off the bus.
★☆☆☆☆ After I added the second set of tickets I purchased just now, the app cannot be opened with no reason. It make no sense not to allow users to save 2 sets of tickets.
