Need new faces for your smartwatch? Try Facer Daily Mix
According to the creators of Facer, Daily Mix is "like a slot machine for watch faces", as it lets you pick one of 10 random watch faces each and every day. Mind you, Facer currently offers nearly 20,000 faces, so there are many, many interesting designs that are waiting to be discovered. As you can see in the video below, it's really easy to find (and change) watch faces with Facer's Daily Mix feature.
In case you're wondering, Facer is compatible with all Android Wear 2.0 smartwaches, and even with Samsung's Tizen-based Gear S3 and Gear S2. You can download the app for free via the first source link below.
