Looks like I forgot to write about this when I released it in February, but Searchlight 1.5 is out!
The big thing this update adds is a widget that can be added to your launcher or to your lock screen on 4.2+ devices. That means you can toggle the light without unlocking the device!
As always you can download it from Google Play and directly from this site.
Also, for the sake of completeness, since I never got around to writing about version 1.4, here’s the download for 1.4.
