Wikipedia for KaiOS

In line with the mission to make the sum of all knowledge free to all, the  is building a Wikipedia app for KaiOS users. KaiOS is a mobile operating system based on Linux. It gives smart-like capabilities to feature phones by enabling the use of apps. These phones come with limited computing capabilities, hardware keys, and a small screen display. It brings popular apps like YouTube, Twitter and WhatsApp to users who wouldn’t be able to afford a smartphone.

KaiOS is used on 160 million devices around the world, with around 100 million active users most of which are Jiophones in India.

Design Research

 * Understanding KaiOS users in India - Report.pdfstanding KAIOS users in India research to understand why and how these users use these phones. We learnt that users chose to purchase these phones because they're affordable and allow access to apps like smartphones do. We also learned the challenges they face trying to read Wikipedia within the native mobile browser. Challenges included ability to scroll through content, text size on the screen, searching for content and lack of awareness that Wikipedia content is available in multiple languages.

Feature Highlights
KaiOS phones have a small, 2.8 inch display, non-touch screen. In designing the app, we had to consider how we would present information from Wikipedia on the small screen size in a way that would provide a good reading experience for the target audience. For the first version, the team wanted to make sure that users would be able to read and search for Wikipedia articles in their language of choice. In the design and engineering, we considered how users would be introduced to Wikipedia, how they discover articles, and how they navigate easily within articles.

Onboarding flow
Research showed that, and other parts of emerging markets, there is low awareness of Wikipedia. We wanted to focus the onboarding experience on defining what Wikipedia is in simple language to a user who may or may not have used Wikipedia before.

Page by page scrolling
Wikipedia articles, at least the really good ones, are relatively long. In our research, users indicated that they found it frustrating to scroll down with the hardware keys as it needed many key presses. We have introduced page by page scrolling, that allows a user to read the article as if they were reading a book, rather than scrolling pixel by pixel.

Language choice and selection
Research has also shown that it is not easy to discover the languages that Wikipedias are available in, particularly in Emerging Markets. We have placed the option to change language where a reader can always see it.

Table of contents
Similar to the Android and iOS apps for Wikipedia, we wanted to give users the functionality to be able to quickly switch to the sections of interest within an article

Article Quick links
At the start of an article, we provided quick links for users to choose how they would like to navigate - they can choose to:


 * see the sections of an article,
 * read quick facts (which is the content in the infobox),
 * See a gallery of images in an article
 * Switch the language of the article
 * Go directly to read the article summary

App availability
The first version of the app was released on 9th September 2020 in India. The app was released to KaiOS users on 7th December 2020. Readers can find the Wikipedia app in the JioStore in India and in the KaiStore in all parts of the world where KaiOS phones are available.

Edit functionality
For the first version, the app does not support editing. Editing articles in the form factor of the KaiOS phone is complex, time-consuming and likely to lead to errors. We are following the work of other teams at WMF, who are working on allowing micro contributions through phones, and plan to provide editing capability in future releases. Editing Wikipedia is still available on the native mobile browser.

Enhanced search function
KaiOS search function allows all words in a user's search query to show results
