Pushover is a small app that let’s you push notifications to your phone in a very simple and elegant way. It’s available on both Android and iOS.
It’s great for all those small things that you’d otherwise feel too lazy to write a proper app for. I’ve used to for receiving notifications of when a build breaks, when people push commit to a certain repository and a bunch of other stuff.
As you can see from this example that I hacked together in CL, they’ve got a great API that’s super easy to use.
