You can use whooing in full by accessing https://whooing.com, whether on desktop or mobile. However, there are no official iOS or Android apps yet. This is not because it has a special purpose, and because whooing specializes in web development, it is not possible to fully develop native apps optimized for each platform. This is also the result of the web standard strategy, which attempts to provide as much accessibility as possible with minimal force in its current state. We are thinking of developing an optimized app if native capabilities are reinforced in the future.
There are still several native apps. There are third-party apps developed by individual developers through whooing's Open API and registered in the market. A full list of these can be found in [Third Party Native Apps] (/help/tips/thirdparty). Where the official website focuses on providing overall functionality, third-party apps differ in that they provide platform-optimized environments for individual developer preferences or specific purposes.
