Does exactly what it says. To be honest, this app gives me the chills. A black screen with a line that moves at the slightest sound. Perhaps, to improve (and if it's not too complicated) add a record function that would record the sound and the line on the screen into a video? Other than that, a brilliant app!
It doesn't work very well I'm sitting with it less than a foot away and it's not picking up any sounds. Positioned fine. App not for me
Doesn't work with my HTC One, the line won't move. But it seems to work on all of my friends phones, so it's probably a fault on my end.
Works Like it Says Thanks helped me to figure out what was wrong with my sine wave.
Great App But This app does what it says it will do, maybe you should add settings to the app, maybe a color options and the ability to record. This seems like a great idea because the app would seem more enjoyable for people looking for a fun and useful app, the app is useful because our phone can probably hear better ourselves. In my opinion, you should add settings if your thinking about updating the app, I suggest you do. And if you do add a settings tool, I'll be sure to rate this app five stars.
Great!! But it would be EVEN better if you can change color, record or maybe even let the user choose an image from gallery as the bg!!
+ Added WAKE_LOCK permission to keep the screen awake while the app is running
+ Fixed bug where wave was a straight line
