Thank you for this app! – MetrO Review

In short, Metro has helpful transit information on a lot of cities worldwide. I used this in 4 cities in Europe and I am really glad I had this. Sure, maybe there are some stops missing from here but still, if you don't have an internet connection or you want to save data while traveling, this app is for you. Tip: you need to know the stop name in order to make use of this (unless the stop is a landmark). I used an offline map app (also free) with public transport stops to look up the stop names.
