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

I was having some issues with larger text sizes being out of place. Also, not sure if it’s intentional, but the scroll button on the bottom right jumps pretty unexpectedly. I would expect it to “go-to-bottom”, but it kind of does whatever it wants.

Seems like most issues, among others, were fixed – thank you, and best

Hi there - I'd love to hear what you think is missing from this app so I can improve. I just released version 2.0 which fixes a critical comment posting bug. Please e-mail me or create an issue via Github.

Edit: the 'scroll button' is used for jumping to the next 'top-level' comment thread.

Room for improvement

Just purchased the app based on the reviews but unfortunately it's not quite there yet.

Couple issues:
- no true black theme
- no automatic switching between light/dark mode
- can only see top stories, can't filter by Show HN, Ask HN, noob stories for example
- when looking at activity, clicking on your comment will link back to main article but without any what to upvote for example

I think with the improvements it can be one of the best apps for sure.

Developer Response ,

Hello! You can change stories from 'Top Stories' to 'New Stories', 'Best Stories', 'Show HN', 'Ask HN', and 'Jobs' by tapping the top left button. I invite you to try version 2.0!

I plan to add a true black theme and auto-switching between modes in the near future. Your feedback is highly appreciated.
