So much value, but...
I use this app constantly. So if you are thinking “is this worth it”, the answer is yes, yes it is.
The developer must have done a ton of work to collect all of the data needed to make this app work and having access to that data is just super useful. On the other hand, the app execution isn’t outstanding. I think tapping each station just loads a static image or pdf file which feels clunky and makes the app pretty large. And… it is fine. I learn what I need to know from the app. Sure, the design keeps me from unequivocally recommending this app to everyone friend I talk to, but if you are already reading the reviews here, you will probably be happy with the purchase.
