Apktool is the original Android application package (Apk) decompiler. Released in January 2010, Apktool is still the most prominent and widespread decompiler available, with tens-of-thousands of downloads every month. The tool reverse engineers third-party binary Android apps (decoding them to nearly original form) and rebuilds them after modifications.
Sourcetoad sponsors Apktool’s development to help ensure that this valuable tool continues to thrive and is free for security professionals, researchers, and enthusiasts to use.
