HarmonyOS (Huawei microkernel OS)

#HarmonyOS by Huawei is a microkernel operating system based on LiteOS: https://www.harmonyos.com/en/

my 5¢

seems mostley a third alternative to Google android based on linux kernel and Apple iPhone IOS.

HarmonyOS is currently availible for SmartWatches, SmartPhones, Tablets and SmartTVs.

e.g.:

https://consumer.huawei.com/en/wearables/watch-ultimate-design/

https://consumer.huawei.com/de/tablets/matepad-pro-12-6/

There exists an development platform called deveco studio, that looks similiar to Android or Visual Studio and is only availible for Windows (64 bit) and Mac (no linux until today planned):

HarmonyOS SDK (Software development kit) contains eTS, arkU & ark compiler:: https://developer.harmonyos.com/en/develop/harmonyos-sdk ArkUI https://developer.harmonyos.com/en/develop/arkUI/ [ https://github.com/ark-lang ] I found on Github several HarmonyOS imitations, like https://github.com/Awesome-HarmonyOS/HarmonyOS
