I've also never liked the built-in Transit functionality in either Google or Apple maps. It always seems like it's trying to be smart, rather than giving me the information I actually want. (The information I actually want is, "should I leave now, or will I just be stranded underground for 30 minutes?" I know how long it takes me to get down to the platform at the stations I frequent, but Apple and Google don't.)

I wrote my own little thing: https://jrock.us/mta.html. It just pulls the train arrival times for my home and work stations, the transfer stations along the way, and system-wide service advisories. It fits on one screen. The code is a trash fire (it's just jquery that injects raw HTML), but it works ;)
