What's a good Android app for booking hotels that actually works when you're in the hospital wifi dead zone?

Okay, so after a crazy 12-hour shift, the last thing I want is an app that crashes when I'm trying to book a hotel room near the hospital. The IHG One Rewards app has been surprisingly good. It's not flashy, but it's got a no-fuss approach that I appreciate when I'm running on fumes. I've used it in the hospital basement with terrible Wi-Fi, and it still manages to pull up available rooms. Plus, I can easily use my points, which is a huge win. It's like having a pocket reference guide for hotels, but without the complicated instructions. I'm too tired to learn complicated apps, but this one's pretty straightforward. It hasn't crashed once in the six months I've been using it, which is saying something. Definitely recommend if you need something reliable after a long shift.
