Hello. I have an IPad with an app called Dream Inducer. It plays ambient sounds mixed with a brainwave frequency. It also has timers. I havent really used it cause its hard for me to sleep with headphones but you guys should look into it. I also have a app called Penultimate which i can write by just using my finger. I use that app for Dream Recall. It's not a keyboard and I don't need to use a pen. Just my finger which is very useful when you just wake up and need to write. I hope this helps.
