First of all: Welcome to the forum! 
You might want to introduce yourself here.
Secondly: Thanks for this complete list, there are many interesting apps, I did not know from. I will link to your post in my topic starter.
I do not use 1MobileMarket any more and try to use web apps instead. To replace the Wiener Linien app, you could use the web app of anachb.at. I just found out today, that you can save recent searches and it works much more intuitive than the mobile page of ÖBB Scotty.
PS.: From your usage of the Wiener Linien app, I take, that you are currently placed in Vienna? If so check out the invitation to our 1. community meet-up next week.
