I decided to write this application because whenever there are delays on my line, I never check tfl website. Sure I could have checked every other day that week, but not on the day with a bad service!
Using this app I can get the current status, weekend status and set up my regular commutes so I get notified if I'm going to be affected by problems. Simple and fast.
We make use of push notifications so it won't drain your battery! ;)
Suggestions and feedback are more than welcome!
This app is open source. Check it here: https://github.com/antonyt/TflTravelAlerts
