DingTalk, Alibaba’s workplace communication tool, has officially started developing a native app suitable for HarmonyOS, Huawei’s operating system, as part of its “comprehensive cooperation” with the fellow tech giant, the Slack-like platform said on Thursday. HarmonyOS has said it will no longer support Android apps in the near future, although a specific timeframe has not been announced. HarmonyOS is already run on over 700 million devices in China as of August this year, and internet-focused companies including ByteDance, NetEase, and Meituan have been actively hiring developers for the Harmony OS in recent weeks.
