This isn't entirely unexpected, but I probably should have known better than to back a kickstarter product which relied on a cloud service. #SmartHalo have gone bust and turned off the servers, rendering devices pretty much useless.

"Since we are not able to pay for server and maintenance costs, SmartHalo 1 and 2 devices have stopped working properly. For those who have devices, you should know that you can always use the front light and the alarm in offline mode, without the app."
