This is a free(open source) software Matrix client for KaiOS which is going to support VoIP calls. Perhaps voice call is already working, in this case please send a Pull Request to update this README.

• Login process with password works(manually or by scanning a QR code)
• Chatting works in all rooms. Sending text and voice is supported. You can view incoming text and photos and listen to voice messages.
• Voice call might work.
• Very experimental and unreliable push notification support which you can enable it in Settings
• You can join public rooms. But there is a bug which you must restart the app after joining. You can also leave rooms but the same bug exists.
• The Cow says "Please wait" to you kindly :))

• Create an issue and report a bug
• Open a Pull Request and implement some wanted feature or fix some bug
• Donate to me (see below)
• Tell others about chooj
• Idle in chooj's Matrix room and help others when necessary
• Solve one of the issues.
• ...

This project has got a Matrix room. See badges.

• You can download and sideload ZIP for each time I push stuff from here.
• OmniSD builds are available there, too!
• Thanks to hashbang which let's me host stuff there.
• Old ZIPs will be deleted after a some time.
• Please allow a few minutes(1-2) after each commit and the file will show up there.

NOTE: While I try to test stuff before pushing but you might find some broken builds there. There is no automated test yet.

This app should work on all KaiOS versions. However it has been also tested on these devices:

• Nokia 8110 4G(aka The BananaPhone)
• Nokia 800 Tough
• Alcatel Go Flip 3 4052W (related issue)
• [Add your own device here]

• Install Node v18.x if you haven't
• Install yarn if you haven't
• yarn install in the project's directory
• yarn devbuild to create a development build(faster build at the cost of heavier bundle) or yarn build for production builds
• Now you can sideload the application in build/ to your device.

You can check guides on how to prepare your device for sideloading stuff and development at the BananaHackers wiki and website linked below:

See this post to learn why I initially chose Github. For future, I might switch to a reliable Gitlab instance(other than gitlab.com) or even have both Github repository and a Gitlab repo and have them in sync. A Gitlab instance exclusively for chooj is also possible if someone funds it but very improbable.

You can also donate KaiOS phones or other hardwares. KaiOS phones with one of more of these properties which are debug enabled will help with the development of project:

• KaiOS 3.x
• Less than 256MB of RAM/Memory
