You can use Hallow while driving, but if it worked with Android Auto, it would automatically pause when maps was giving audio directions, etc. It would also be able to be on the navigation split screen (map on one side, audio controls on the other).

I would be able to use Hallow much more safely and more often while I was commuting if it was Android Auto compatible… need maps up with traffic data

This would be helpful. However, I often use Hallow in the car by plugging my phone in and just starting the audio on Hallow that I want to play. It works great. I pray the Rosary while driving, listen to audio books, homilies, or the reading of the day.
