きかんしゃトーマスせんろをつくろう is a lifestyle Android app developed by neos. It offers a fun and interactive experience for users to create their own train tracks with Thomas and Percy. The app features two modes: "かんたんモード" (Easy Mode) and "じっくりモード" (Detailed Mode).

In the "かんたんモード" (Easy Mode), users can easily control Thomas and his friends by simply tracing their fingers on the screen. This mode is recommended for beginners and provides a sense of achievement as users see their trains running on the tracks they created.

The "じっくりモード" (Detailed Mode) allows for more advanced customization, including elevated tracks and branching paths. This mode offers a higher level of difficulty but provides more creative freedom for users to build their own unique train tracks and towns.

One of the notable features of the app is that Thomas speaks during gameplay, providing audio guidance to enhance the user experience. Additionally, users can enjoy Thomas' videos within the app, and there are special character stages available.

The app also offers a timer feature to prevent excessive playtime, ensuring a healthy gaming experience. With its user-friendly interface and engaging gameplay, きかんしゃトーマスせんろをつくろう is suitable for users of all ages.

Please note that for additional features and benefits, there is a monthly subscription option called "あそびほうだいコース" (Play Unlimited Course) available, which includes character additions, save/load functionality, timer control, and ad removal.
