At the Galaxy Gear’s announcement, Samsung stated that the Galaxy Gear smartwatch (that right now works only with the Note 3), would launch with more than 70 apps (which are available through Samsung apps). Folks at droid-life have received a review unit from Samsung and they comment that only few of the important apps have been made available that includes Evernote, Path, Snapchat, Vivino and some more. Downloading apps to your Samsung galaxy gear sounds very easy – just open up the gear manager app on your Note 3, and open up Samsung Apps. Here are few of the screenshots of Samsung Apps user interface.
Just select the app and hit the Install button to install it on the Gear. Keep in mind that only those apps that are compatible with the Samsung smartwatch (as shown in the below screenshot).
