Google's Handwriting Input app now available for smartwatches running Android Wear 2.00
So let's make this easy for you. If your watch runs on Android Wear 2.0 either because it received an update, or because it shipped with it installed, run to the Play Store and load the Google Handwriting Input app for your watch now.
The Handwriting Input app works exactly like the name suggests. You draw a letter, number or punctuation using your finger. Google suggests words based on what it thinks you've written. This might be the best solution for those with large fingers who just can't navigate the QWERTY on a watch face.
The app is free and can be installed by clicking on this link.
