Very useful but buggy
I rely on this app every day. It has saved me a lot of time and frustration and is more accurate than "Transit", which seems to only know what ought to be happening, rather than what is. My main complaint about MTA Bus Time is that it periodically locks up while showing an error message that the internet connection is faulty. It never gets working again once it is stuck on this error. The only way to get it functioning again is to delete it and download it again. I have had to do this at least five times in the past 6-8 months.
