DokoDoor makes your journey a little smarter and smoother.

[Supported routes expanding]
We plan to gradually add support to routes currently unavailable.

[Do you have these concerns?]
- Short transfer time! I want to get off right in front of the stairs.
- Since I'm using a stroller, I absolutely need to know which car has an elevator.
- Searching by entering station names is a pain.
- Poor signal on the subway, so no search results.
