licensing open-source-software
Does the Apache 2.0 license require attribution on a commercial work on which it is based?
<p>I'm using <a href="https://github.com/NativeScript/NativeScript/blob/master/LICENSE" rel="nofollow">Nativescript</a> which is licensed under the Apache 2.0 license.</p>

<p>Provided that I do not intend to change Nativescript itseft, but I'm using it to develop an application, am I expected to give attribution to the license and/or Nativescript in the final app that I deliver?</p>

<p>Yep, you are.</p>

<p>You still need to keep the LICENSE and NOTICE files in the repository, if there were any in your copy of the project. These files contain the terms and conditions for the project, and provide attribution to the original developers. If you're trying to attribute in the UI of your application, you probably should. It's considered courteous and in the spirit of open source as well.
