# Overview

During the development of your app, you may experience issues with your app and/or API. Therefore, you will need to use the [Make DevTool or the console](https://developers.make.com/custom-apps-documentation/debug-your-app/make-devtool) to debug your app.

Here are some examples of specific debugging issues you may encounter:

* [Pagination in list and search modules](https://developers.make.com/custom-apps-documentation/debug-your-app/debugging-of-pagination-in-list-search-modules)
* [Remote Procedure Calls (RPCs)](https://developers.make.com/custom-apps-documentation/debug-your-app/debugging-rpc)
* [Custom IML functions](https://developers.make.com/custom-apps-documentation/debug-your-app/debugging-of-custom-iml-functions)
