Hacker News YC 2.1 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X was originally designed by Dharmesh Patel.
According to the results of the Google Safe Browsing check, the developer's site is safe. Despite this, we recommend checking the downloaded files with any free antivirus software. The program lies within Internet & Network Tools, more precisely RSS Tools.
From the developer:
Hacker News YC is a clean, simple, and modern-looking app that lets you read Hacker News articles and comments. The tool provides you the ability to up-vote or down-vote comments. In addition, it allows you to share stories and comments. Optionally, you can save the articles for reading them later.
