Great idea. I was looking at this app recently but downloaded a free supposed equivalent. I will get it now. I suppose using my phone for recording will not mess up the results since indeed I will be awake while recording .

The app I'm using for RC reminders on iOS is Lucid Reality Check By KitschMaster. Kind of annoying custom interface, reasonably configurable, but can't use your own sounds at least not in the free version. I've tried using it for morning alarm-based DEILD too (set the exclude times to be FROM 8am TO 6am in order to enable this mode) but I haven't had luck with that mode and now I'm using remee for that purpose.

I still want to write my own lucid dreaming app as I can write iOS apps. I'll get to it one day .
