i found this article a few days ago on Engadget about fleksy a keyboard which you can type with without even looking.
Smartphone typing like a Boss...
Works just great on Galaxy gear. Typing is so easy with this.
You need Xposed framework. I suggest flashing _null Rom and using this guide epsecially this post
Install Fleksy on your Smartphone.
Backup apk in an .APK file format:
Install SuperManager on your Smartphone
in SuperManager Tap on APK Manager
Tap on fleksy
scroll the menu down on the bottom to the left an tap on "bAPK"
Tap on "Showed Name"
Send APK to Gear:
Open a file browser of your choice
Browse to "SuperManager -> MyAPKs"
long tap on your file
send via Bluetooth
select your gear
Confirm those sending messages
Browse to Bluetooth folder on Galaxy Gear SD
Now it's time for rescaling or you can not use fleksy because one Button does not show up. so you can not finih the startguide
If you setted up App Settings for Xposed Framework properly you browse to settings - > App Settings -> fleksy
Tap on it
Turn it on
Now Set the DPI to 60.
That works for the startguide.
Than you can mess around which settings fits your needs best.
