Companies often create apps in the same problem domain with similar features. Implementing these features over and over again is inefficient, time consuming, and error prone. This leads to high costs for the developing company and prices which are not competitive on the market. To address these problems we identify reusable features and implement them in a library which is well tested and allows frequent reuse. Features include navigation patterns, lists, menus, animated components, shared components, gallery and so on. With the help of these features programmers can easily create various applications with good design and functionality, reducing the time spent on development and allowing competitive prices for related services and products.
