I just installed Pushover (https://pushover.net/) which seems to do the same thing for both iOS and Android, seems better designed and gets bonus points for IFTTT support.
I considered that one too. But for most of the things I was interested, pushover had no support. Currently getting notifications from Nagios, OpenNMS and a custom Arduino I use on my door bell.
The screenshot on the Pushover site is hilarious with the "Download of 'Not illegal copyright infringement in anyway.mkv' complete" and icon of Transmission BT.
Yeah, i've been using this to send notifications from our Nagios to my Android and also on a couple other applications to notify me on certain events. Really cool.
