AOdia is a free Android app developed by KameLong in the Travel & Navigation category. It falls under the subcategory of Maps & GPS. With AOdia, you can create your own timetable, specifically for train times at each station. The app allows you to make a list of stations and add trains with their corresponding times at each station.

One of the key features of AOdia is the ability to view a train diagram based on the timetable you create. This can be helpful for visualizing the train schedule and planning your travel accordingly. It's worth noting that the current version of the app is only available in Japanese. However, the developer is actively working on translating the app into English.

If you are interested in using AOdia, you can follow the developer on Twitter (@kame_long) and provide feedback and comments. Your input will not only help improve the app but also motivate the developer to continue working on it.
