Does it have creamed spinach noise? ("Creamed spinach" refers to the color used in the DMG Game Boy's screen, as Sega referred to it in one of its Game Gear commercials)
How battery intensive is it? I tried sleeping to a brown noise audio file in a normal music player app (Music Player Go) and my phone ran out of battery before my alarm went off, causing me to oversleep 😬
If you're the kind of person that plays on their phone to fall asleep, get a 10' cable so it can be plugged in while you're doing whatever you do before sleeping.
This app was fully offline previously. Now with premium thing they removed it and i cannot turn of my mobile data to sleep. So this ruined the whole experience for me.
