LucidWeaver is the world's first lucid dreaming training software for multimedia mobile phones with Java.

Lucid dreaming means knowing that you are dreaming while it is happening. It is a learnable skill that allows you to decide what is going to happen in your dream. You can control your dreams or soar up to the sky!

LucidWeaver gives you periodic sound cues called Dream Alarms during REM-states when dreams are seen. This will greatly improve your dream recall which is crucial for learning lucid dreaming. Dream Alarms can also be used for advanced lucid dreaming practice. LucidWeaver keeps on reminding you to do Reality Tests during day. Of course LucidWeaver can be used as ordinary alarm clock.
This is pretty neat. You can set a special alarm to go off 6 hours into sleep and then every 90 minutes.
The alarm is very subtle and doesn't startle you.

This is great for anyone who wants to try DEILD or signaling for a RC.
You are also able to adjust the alarm intervals to your needs.

Enjoy
