While doing a Google search for ASMR, which I do practically every day, to see what comes up, I saw a page on iTunes for a new ASMR app. This was followed a few days later by a YouTube video demonstration.
This app was developed specifically for any product using iOS 5.0 or later by Sandratra of Sassou Studio, and is available off of iTunes for 99 cents. Version 1.0 is small, at about 200 KB.
What it features is direct YouTube browsing, with YouTube videos sorted by category (which seems to have a connection to asmrvideos.com), favourites management, as well as direct access to The Unnamed Feeling blog. It also sports in-app support by email or comment. There’s also a support page which is listed on the iTunes page mentioned earlier.
As long as you have an iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPod touch (3rd generation), iPod touch (4th generation), iPod touch (5th generation) or iPad and have iOS 5.0 or later, this app might be worth looking in to.
Update: This app has been updated to v 1.1 as of October 2, 2012. Some bugs were fixed, and the app has been renamed ASMR Mobile.
