Application ios - city bus schedule, template or how to do it yourself?

Question

iOS

I would like to know how to make such an application that would show the bus schedule by bus numbers. With the ability to update the schedule in the application. Perhaps there are similar templates somewhere that could be easily tweaked and configured ... The functionality does not look very complicated, but so far I am just starting to understand this issue and there is not much knowledge. Let me know if anyone has information on this issue or perhaps suitable templates.

Answer 1

Why create something that has already been created? For example: Yandex transport

Answer 2

This is for a small city in another country, Yandex.transport does not work there)
