There are 4 screens, each has a navigation bar at the top:
1. Home: For selecting the stations to see times for.
2. Stations Chooser: For selecting from the list of stations.
3. Train Times: The list of trains from a station.
4. Journey Details: The stops a particular train makes.
For full details of the exact elements each screen needs to include, please look at the Screen_requirements.png file.
I have also included a file showing the current design details, including the app's icon: Current_design_details.png
Screens_as_they_are_now.png shows what the screens look like now (very basic and functional!).
Apps_with_similar_functionality.png shows 2 apps with similar functionality, and a design concept for another I like the style of.
The main people using the app will be people travelling to work. Their primary reasons for using the app will be to check if their train is running late, and see what platform they need to go to.
Before leaving the house for work I'll check to see if there are any issues with the trains.
When coming back from work the station I use has 19 platforms, so I use an app to find out which platform the next train to my home station is leaving from.
