Yes, it is possible to create an app without coding. Several platforms offer app building without having to inject your code. The features are pre-made and can be put together to create an app of your own. Some of the platforms available include the following: Andromo, AppsGeyser, AppMakr, GameSalad, Appy Pie, Appery and Swiftic.
Using any of these platforms to build your app is a much cheaper and quicker process. However, there are many limitations to this process. You are limited to only using the features that have been pre-built in the platform, which may not give you the results you are after, and may therefore not produce an app that stands out from others. Additionally, creating an app on your own means a lot of trial and error, especially when it comes to uploading it to the app stores and following their comprehensive and specific guidelines.
