A few Note 3 Apps have been ported to the G2
Morning (smart alarm): Alarm app that reads out weather, news, traffic, and new emails.
Sketchbook: stock Note 3 sketchbook app
Both apps work great on the G2.
The Samsung Remote app has also been ported, but I haven't tested it since I'm using the stock LG app.
