We heard everyone loud and clear: you wanted an Android app. We're happy to announce that our Android app is officially on the Google Play store!
It's currently in a "public beta" state. This means that it's quite stable; it has most features from the Mac and iOS apps, but it's still missing a few things, such as viewing visitor attributes, DND controls, etc. This will all be added in short order, but we wanted to get it into the hands of users as soon as possible. Please let us know what you think by popping onto our live chat at firehosechat.com.
It is not currently possible to upgrade to premium through the Android app, but we've just announced our own subscription service that doesn't require a Mac or iOS device. Simple visit https://billing.firehosechat.com/login to log in, choose your plan, and add your credit card.
Lastly, a spoiler: Web app is next!
