Hate to break it to you (and your friend), but there are absolutely no apps that record dreams (of any kind). There are apps that supposedly help you reach the right state of sleep...but that's about it. I'm fairly certain that you can get mp3's that'll do that.
Save yourself the trouble and meditate for free...follow lucid dreaming guides online. Shortcuts USUALLY don't work...either way, you'd look silly sleeping with a phone.
The lucid dreaming app from Alexander Stone works very good. It records your dreaming activity. If you want better data you can even connect it with a Zeo Mobile.
How exactly does an app record your dream? Jack into your brain? Do you connect electrodes to your body? Maybe it wirelessly connects, or has special x-ray dream powers?
Nope, it uses your phone's gyroscope/accelerometer to monitor the movements of your mattress, and somehow figure out your sleep pattern in that way. Doesn't record your dream, just figures out your sleep pattern, and then uses some sort of voice reminder when it believes you are in REM sleep to trigger lucid dreaming.
EDIT: FYI, took about 20 seconds of research for me to find this.
