5 stars: Accurate and easy to use.
3 stars: Th often it will not show the best choice of buses and shows instead changes that have 2 minutes of change time, although it's common for a bus to have 2 minutes delay. The specific bus combination that I have just used was not listed but it was given as option for 1 hour later, although there was a connection every 10 minutes. The application works more or less but is not always reliable.
3 stars: Good app for basic info, but network maps are limited (ex. no map with complete metrobus stops) and no price is shown for some trips (ex. via regional trains). I know you can download the other maps from the website, but only the pdf versions are available and it would be nice if all these can be viewed through the app instead or an image version is downloadable from the website.
4 stars: Very helpful and accurate. It has all the features one would need. Also possible to buy tickets online that makes it a bit cheaper than a paper ticket. I just found the map a little slow hence no 5 stars. I would have given it 4.5stars but didn't have the option. The infos here are more updated than in the google map, which includes change of route due to \
5 stars: After the rework/recode, this app really is useful now! I don't own a permanent traffic ticket subscription and regularily use the app to quickly buy my ticket in literally seconds! :) Some inter-region trains do not update as fast as one would wish but as an IT-guy, I can bet...
