In Verfolgung des Auftrags, die Summe allen Wissens allen Menschen frei zugänglichzu machen, entwickelt das Inuka-Team eine Wikipedia-App für KaiOS-Nutzer. KaiOS ist ein mobiles Betriebssystem auf Linux-Basis. It gives smart-like capabilities to feature phones by enabling the use of apps. Diese Handys kommen mit begrenzter Rechnenleistung, Hardwaretasten und einen kleinen Bildschirm. It brings popular apps like YouTube, Twitter and WhatsApp to users who wouldn’t be able to afford a smartphone.

KaiOS-Nutzungserforschung für Indien

KaiOS wird auf 160 Millionen Geräten auf der ganzen Welt verwendet, die meisten davon sind Jiophones in Indien. The Inuka team ran qualitative research in India 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.


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.

Funktionelle Besonderheiten


Research showed that, in India 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.

Welcome to Wikipedia screen on KaiOS


Wikipedia-Artikel, zumindest die wirklich guten, sind relativ lang. 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.

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.

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

Schnellverlinkungen innerhalb von Artikeln

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),
  • Siehe eine Galerie von Bildern in einen Artikel
  • Wechsel die Sprache des Artikels
  • Go directly to read the article summary

Verfügbarkeit der App

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.


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

Wikipedia für KaiOS Version 1.6.0

The Version 1.6.0 was released in early 2021 with:

  • A content engagement experiment: half of the users in Nigeria, Uganda, Pakistan and Tanzania will see a feature that shows a daily refreshed list of Trending articles in their country
  • Ability to share an article URL
  • No QuickFacts button from article actions
  • Verbesserte Lokalisierung

Reichweite der App

Wachsende App-Verwendung

As part of the Wikimedia Foundation's partnership with KaiOS, in January 2021 we began running advertisements to increase the visibility and downloads of the Wikipedia app on the KaiOS platform. As most KaiOS adopters are first-time internet users, they are far less likely to know that Wikipedia exists—let alone use it on a regular basis.

KaiOS regularly displays small banner ads to their phone users while they are browsing the internet, and we are using their standard process for placing our ads. Each of our banner ads are composed of two parts:

  • Eine kurze Nachricht über Wikipedia
  • A button that brings users to Wikipedia's listing in the KaiOS app store where they have the option to download it

These ads are running globally in English, Spanish, French, and Arabic, languages which cover approximately 90% of KaiOS's current userbase. No ads are or will be run on the KaiOS Wikipedia app.
