It works. Great app. It seemed not to work after the kk 442 update for the Samsung GN3. But if you enable and open Samsung's s voice and disable the home key to open option and re-disable the app it will no longer interfere with this great customization. Thanks to +Stephan Sanchez on G+ for pointing this out. I use it as a quick double tap of the physical home key to Google Now. Edit:doesn't work well with Nova launcher but wasn't really necessary.
Works great on my Galaxy S3, with KitKat 4.4.2. I've mapped the Google app to a double-click, which gives me easy access without using the Google Now Launcher. NOTE: IF you're having problems on a Galaxy device, make sure you disable "Open via the home key" in the S-Voice app settings. If you don't do that, then Home2 won't bring anything up on a double-click, even if you turn off S-Voice.
Sheer genius, incredible function added. Cons: interface is not the easiest to setup. Pros: doesnt matter. Set it up once and you are set. Using this app in combination with Google Now, google now actually necomes useful. It is only a brief button click away thanks to this handy app, lending android devices Siri-like voice accessibility. If I had to pay for tgus app, that would be ok. It would be worth it.
Does what its supposed to do... But poorly. I have a droid turbo running 4.4.4 and the shortcut works but every time I press my home key I see my multitask menu for a second. I understand this is the app waiting to recognize a second home key press, but it wasn't always doing this. An official release of this app would be nice. If I get a reply I might donate.
PLEASE FIX to work with KitKat Worked wonderfully (5 STARS) until I upgraded to 4.4.2 KitKat release. I have Galaxy Note 3 with T-Mobile, and after updating to KitKat, it doesn't work at all now. Emailed developers, no response. Awww, too bad, was a really great tool to use Google Search on double pressing HOME.
Stopped working with KitKat I installed Kitkat and the app stopped working after a few hours as others have mentioned. The home key works to bring me to TouchWiz home but I can't double tap the home key to bring up another app. I have a Galaxy Note 3 with AT&T. This used to be an awesome app. I will modify to 5 stars if it is fixed.
