# Debugging

Source: https://developer.repebble.com/guides/debugging/

When writing apps, everyone makes mistakes. Sometimes a simple typo or omission can lead to all kinds of mysterious behavior or crashes. The guides in this section are aimed at trying to help developers identify and fix a variety of issues that can arise when writing C code (compile-time) or running the compiled app on Pebble (runtime).

There are also a few strategies outlined here, such as app logging and other features of the `pebble` [_Command Line Tool_](https://developer.repebble.com/guides/tools-and-resources/pebble-tool.md) that can indicate the source of a problem in the vast majority of cases.
