The Apple Watch is not a smaller phone, just as a smart phone is not a smaller computer. Raluca Budiu recommends the following for UX development for the Apple Watch: (quoted from her article The Apple Watch: User-Experience Appraisal):
- Distill the essential content that people are interested in and present it in a compressed form that would fit the tiny watch screen.
- Avoid buttons and complex navigation as much as possible, and if you do include buttons make them few and big.
- Use handoff to phone to enable users to get more details and solve problems that require more complicated interactions.
- Create standalone bits of text that can easily be read and comprehended and truly convey the gist of your content.
