LucidWeaver uses Java J2ME configurations of MIDP2.0 and CLDC1.0. Your mobile device has to support these or higher in order for the LucidWeaver to install and work. Check your manufacturer's manual or web page: Sun's list for Java J2ME support in different manufacturers' devices.

See above.

LucidWeaver uses Java Virtual Machine on your mobile device. Java Virtual Machine will take more power than regular use of your mobile device. Just keep your battery charged when you go to sleep so that the 'battery low' alarm will not wake you up. Exit the LucidWeaver when you are not using it during nights or days. Please note that you have to use the Exit menu command or the LucidWeaver will remain on the background of your mobile device and Java Virtual Machine will consume the same amount of power that it would when LucidWeaver is on the foreground.

Check that application and warning sounds are turned on in your mobile device settings (not part of LucidWeaver). On some phones "silent" profile means that no Java application sounds are heard. Check also the volume level of your speaker. LucidWeaver uses Java Mobile Media API (MMAPI) sounds and these can be turned off from some mobile devices' settings. Check your mobile device's manual on how to turn on warning sounds.

LucidWeaver uses Java Mobile Media API (MMAPI) sounds library. If your mobile device doesn't support this, sounds can't be heard. Sorry.

"I set vibration from LucidWeaver settings but my mobile phone is not vibrating when dream alarm comes"

First try to activate a profile from your mobile phones settings that has vibration active. If this doesn't work then Java vibration functionality has not been implemented by your manufacturer for your mobile phone even if your mobile phone vibrates when you are not using Java application. Sorry.

J2ME Mobile information device MIDP2.0 is relatively new release in Java technology and mobile phones that are older don't support it. So why use it? That's because of sound support. There was practically no sound support in earlier versions of MIDP. Sounds in games etc. were made with vendor specific interfaces. MIDP2.0 MMAPI (Multi Media API) is platform independent and that's why it is used in LucidWeaver.

LucidWeaver is designed for mobile devices. There are however some Java or J2ME emulators for PCs. You can try for example Sun's emulator. Download and install Sun's J2ME Wireless Toolkit (WTK). Your desktop's browser should open LucidWeaver to your computer after this if you download it from www.lucidweaver.com.

Try to get your mate excited about lucid dreaming so that you both train with the same lucidity cues from LucidWeaver. After all this might be the other fun thing you do together in bed :)

LucidWeaver was donationware for two years. Not a single donation were made. So much for charity :)

Currenly LucidWeaver is a non-profit project. However there are cost for keeping the LucidWeaver site open. This is why there is a marginal cost for the software.
