Excellent app for reading hacker news. Runs smoothly with no IAP needed. Probably the best HN app I've been used. Thanks for your hard work on developing it.

P.S. If you lived in China mainland, you'd probably need some tools to bypass the notorious GFW. ¯\_(ツ)_/¯

However this is the U.S. app store, not the Chinese one with the bullsh*t Guizhou Cloud Big Data which sells your personal data to 3rd parties. If this app can't get news for you, then developer is the least likely to be blamed. Posting a 1-star review definitely dose no help.

Thank you!

Could you please add the search feature?

Awesome product! Sometimes I would like to see comments on recent articles. It would be great to have search feature with sorting function by relevance or date which is included in MiniHack app (another Hacker News app which I used previously before Octal). Thanks.

Developer Response ,

Hello, I've added Search with an option to sort by Relevance or Date in the Settings since v2.9.0. Thank you for your suggestion!

Good HN App

This is the best HN reader I have found, and I’ve tried quite a few. I paid for full/premium, which allows you to post/comment and offers more customization options. I haven’t encountered any bugs and overall it’s a solid interface to one of my favorite sites for a reasonable price.
