I hate to necropost and mention my app again, but since this is the top google search result for "android lucid dreaming", I have to do this, as it may benefit new dreamers. Here it goes:
I've spent some time developing an Android Lucid Dreaming App which will please lucid dreamers. It is completely free, has no ads and offers the best features of other apps that lucid dreamers might've used in the past . It is built by a lucid dreamer for lucid dreamers!
The app lets you combine voice and vibrate reminders and schedule them to be played during your suspected REM cycles. The app also tracks sleep through actigraphy and is geared towards lucid dreamers - you can enter dream related events (drems/LDs/awakenings) with a single gesture. These help track sleep cycles better, so the generic do technique after 5 hours becomes a very specific "do technique after 4:30 to 4:50", because you've reported dreams at that time frame. Furthermore, the app adjusts next sleep cycle REM event based on the events entered earlier in the night.
This means that if you wake up, make a dream gesture for the app, write a dream in your dream journal, go to the bathroom, etc the app will account for that when delivering the next reminder.

Lucid Dreaming App » It works!*
Here's an example of a few days of data with dreams as orange triangles, suspected REM episodes as red lines and Xs as places where the app would've delivered the reminder (based on current config - see how it would change the app's behavior!)
