Keep, Google's cloud-based note taking app, has always been pretty handy. But having to pull out and unlock your phone, then launch the program, open a new note and finally type in your thought is often enough to make anybody yearn for a pencil and pad of paper. Luckily, Google has a newly updated means of jotting down ideas as easy as talking to the back of your hand -- you just need to shell out a couple hundred bucks for an Android Wear watch to use it.
According to the official Google Android Blog, Android users with devices running Ice Cream Sandwich and newer will be able to access the Note app directly from their wristwatch while leaving their phone in their pocket. Users can activate the app with "OK Google, open Keep" or jump directly to dictation with the command "OK Google, take a note." Existing features like swipe-and-tap navigation and adding reminders to existing notes directly from the watch are still supported.
