Before jumping into the development phase, we recommend you to draw up a wireframe of your application. A wireframe is a visual and schematic representation of the layout of your application. It focuses on information and navigation.
The wireframe allows you to have a working document with your stakeholders and to avoid a lot of mistakes when building the application. In the end you save time and optimize your work process.
Then choose the perfect app builder based on your needs. There are many no-code platforms in the market to create apps without coding. Build and preview instantly to make sure user experience is the best.
Before app publishing, make sure to test your app is perfect on every platform.
