Latest update ruins Apple Watch app

The latest update has ruined the Apple Watch app that is paired with NJ Rails. Ive been using NJ Rails and the Apple Watch app for awhile now, and its been working fine. But since the update, when I launched the Apple Watch app, it wouldnt load at all, and eventually returned me to the home screen. So I just left it. But then I realized my iPhone was getting really hot, but I didnt look into it. Then I realized about 5 hours later, my battery had dropped from around 90% to 30%, but I barely even used my phone. I checked the Battery section in the Settings app, and I found that NJ Rails had been consuming 60% of my battery usage, and it was running 6.5 hours in the background.

I will be deleting this app until the developer of NJ Rails comes up with a fix.
