Hey Mike,
Thanks for the feedback and for flagging the outdated data. Right now, I run a job at the start of each month to pull the latest fares (this takes about 3 days) and then I manually trigger an app store update. Ultimately, I would like to decouple data updates from app releases so I can refresh fares without requiring a new build.
In the meantime, I have added an “updated” timestamp to the bottom of the home screen so users can see when the data was updated. Down the road, I plan to include an online fetch option to pull fares directly from TFL whenever the device is connected.
Google should approve these updates sometime on the 8th July, let me know if you have any other thoughts!
