Apps on feature phones? Everything you need to know about the KaiStore


It sounds like an oddity: apps on a (“dumb”) feature phone. Until now, the smartphone has been the domain of apps and their stores. With the launch of the KaiStore on KaiOS-powered devices, this smartphone-monopoly on apps ends.


The similarities

Conceptually, the KaiStore is no different from a store for apps on other devices. You can browse app categories, like social media and games. You can read a preview, find info on the developer, and download the apps you like. Many are free, some are paid, others offer in-app purchases. KaiOS also supports push notifications, just like a regular smartphone.

Another similarity is the type of content you can find in the KaiStore. We have signed up many of the world’s most popular apps, like Facebook, Twitter, and several from Google (Google Maps, Google Search, and the Google Assistant). In the coming months, many more titles will be added in categories like gaming, streaming entertainment, travel, social media, and health.

So far, so similar. Now letโ€™s look at what makes the KaiStore different!


Closing the digital divide

Our mission at Kai is to close the digital divide, and the KaiStore plays a central role in this effort.

Reducing digital inequality doesn’t end by solving device affordability, digital literacy, and data pricing (more details on these issues in this post). Resolving these problems is crucial, but they’re only the beginning.

The next important step is to create relevant content (including apps) specifically for those who access the (mobile) internet for the first time. For example, we partner with Google and make Google Assistant available in the KaiStore. Users can use their Google Assistant to find answers, get things done and open apps using nothing but their voice โ€“ all they have to do is press and hold the Google Assistant button to get started. Simple and convenient! So in the coming months and years, we will be turning more of our attention to help bring more apps to the KaiStore that are developed with this unique target audience in mind.



The KaiStore will be curated for the foreseeable future. Any developer can submit suggestions for apps and all of these will be reviewed by the KaiStore team.

From these submissions we will select the apps that are most fitting for KaiOS and our target audience, to guarantee the best possible experience for our users. We will make the review criteria transparent and easy to understand in order to improve the chances of a successful submission.

While we want to provide as much relevant content as possible, we also want to ensure a high level of quality and make it easy to discover new apps. We can only do this by slowly increasing the amount of content, making improvements to the KaiStore as we grow.



The entire KaiOS platform is based on HTML5 and supports JavaScript. This means itโ€™s relatively easy to create apps (and other content) for KaiOS, especially when an HTML5 website is already available.



To support our unique form factor and target audiences, weโ€™re building an entirely new advertising solution specifically for feature phones. This product will help app developers monetize their apps in the KaiStore.

KaiAds will support innovative ways of monetizing content on (feature) phones, for example with a lock screen solution, as well as pre-rolls and post-rolls at specific moments in the app.



When? When? When?

The KaiStore will go live in several countries in May (details to follow) and continues to be rolled out on a country-by-country basis from there onwards in close cooperation with our partners. We expect the KaiStore to be live in most countries and on most devices by the end of 2018*.

Curious about developing apps for KaiOS? Head over to our Developers page and leave your email address. We’ll notify you shortly when we have more detailed information about developing apps for the KaiStore.


* Please note that while technically the platform is the same, app development submissions and content for the JioStore (the store for apps on the JioPhone) is being managed by Reliance Jio.

    In kaios need fille manager and document reader (PDF,word, excel, powerpoint and more). In this moment is Nokia 8110 my best phone.

    • Kai Helps

      Hi there! Thank you very much for your feedback. The File Manager is not available on the Nokia 8110 4G. We are working with device manufacturers and they may determine if a certain feature is implemented or changed. I’m afraid it was Nokia’s decision not to include the File Manager on their devices. As for the document reader apps, I have forwarded your suggestion to our product team, so they could consider it for the next versions of the KaiOS. We appreciate you being so engaged!

    Importing contacts from gmail is nice, but Sync will be much better.
    until then, is there a web based access to import contacts ?

    • Kai Helps

      Hi Daniel! Thanks a lot for reaching out and your interest in KaiOS. As of now, you can only sync your Gmail contacts with the Contacts app manually, apologies if it may cause any inconveniences. Regarding the way to sync them by using web, it wouldn’t be possible, as you can only synchronize the contacts from Google/Outlook with the app from the app itself. Still, I have forwarded your suggestion to improve the synchronization of the contacts to our product team, so they could consider making the necessary changes in the next software versions. Thanks for your feedback!

    On SMS (Messages) app, when you have the list the Call button is not working to call sender.
    When opening message detail, also call button is not supported. (In options menu, there is a call entry).
    Please add this intuitive call key functionality.

    • Kai Helps

      Hello! Thank you for having taken your time to provide us with your valuable feedback. Your helpful comments are much appreciated, and your feedback will help us to continually improve our OS. I have forwarded your request to our product team so they could include this feature to the next version.

    Hello! Thank you for your comment! Regarding your question about apps such as LINE (lite), Skype, WeChat, Telegram, I cannot comment on specific dates and release. But be sure that We are working every day to extend the range of apps we can provide to you and hope for your understanding during this time.

    Hello KaiOS! I’m just about to leave my Android flagship to try KaiOS for a while. I find smart phones too much of a distraction and waste of time. It seems that KaiOS and the new Nokia 8810 makes for the perfect phone that is simpler and less distracting but also capable enough to do everything required on a day to day basis. I can still use my Bose earphones to listen to music over Bluetooth with the Nokia, I can still use Google Maps to find my way around London, and most importantly I can do all this without worrying about having to recharge my phone every day. Furthermore the money that I’ll save if I end up not upgrading to the Note 9 will pay for a really nice camera!

    Too bad about WhatsApp still being missing. But I think you guys know that it’ll be a huge boon to KaiOS to have WhatsApp and I’m sure you’re working on it. As more and more people are getting tired of being glued to their phones 24/7, WhatsApp will come to you if they know what’s good for them.

    I just have one question, when will the KaiOS store be rolled out in the UK?

    Thanks for everything!

    • Kai Helps

      Hello! Thank you for your feedback! We are planning to bring KaiOS to many more countries in 2018. However, I cannot pinpoint to a specific time when the UK will be included. We are working with OEMs (device vendors) and the delivery plans are under their control. I would recommend contacting the device manufacturer you had in mind directly for more specific information.

    • Kai Helps

      Manitesh, if you wonder about the Facebook Messenger app, it is currently not supported in KaiOS. Good news is that WhatsApp is supported on JioPhone devices, so make sure you update to the latest version. Anyway, if you have questions regarding apps or if you would like to request an app, we recommend contacting Reliance Jio directly.

    Are the VOIP calling apps on KaiOS compatible with Skype audio. This is so that VOIP calls can be done between the Nokia 8010 and an iOS or Android device?

    • Kai Helps

      Mohamed, in general, VoIP is supported in KaiOS. However, there are no apps that could use VoIP. We are of importance of such apps and hope to introduce more apps and features in the future.

    Is Whatsapp download supported on Nokia 8110 ? what about Facebook ? I can only see Twitter available for download in the store. I feel i am let down by the person who sold and told me that Whatsapp was available on 8110. This was taken as a back up phone for the battery life.

    • Kai Helps

      Mervin, thank you for reaching out. Indeed WhatsApp is only available for JioPHone users in India. However, in Nokia 8110 4G, Facebook and WhatsApp are currently not supported. We totally understand their importance in a modern-day world and hope to introduce more social media apps in the KaiStore in the near future. Please stay tuned for the updates.
