The usability could be defined as the easiness to use or learn to use something. The higher the usability is, the easier and more satisfying the user's interaction will be with the final product.
An App should be easy on the eye and be intuitive in navigation. In order to achieve this, here are some basic notions to follow:
- Colors and texture should enrich the total vision, not bother it.
- Texts should be readable in size and font type.
- The navigability through an App should be fluid and intuitive. It should be based on a well structured and categorized navigation menu with easiness of return to former pages or main sections. Dead end pages without ¨back¨ buttons and non iconic icons should be avoided in order to have a more intuitive and comfortable experience.
Following these guidelines will help you build an App which offers a more professional image and better experience for the final user.
