The app is great, but I don't understand why they changed the icon. This icon does not show the harmonics while as the previous one showed 3 harmonics. At first, I thought this icon showed one harmonic that was slightly shifted to create a copy, but it actually shows no harmonics. Neither of those copies is a correct sine wave. But the app is really good, and it somehow updates itself, so I don't have to. Thanks for building and sharing it.

Excellent, clean reader for Hacker News. The UI doesn't get in the way and makes navigation intuitive.

Good app for my hacker news needs, sometimes though the inbuilt pane of web preview does not work or stutter. But overall nice design and beautiful looking app for hacker news

Looks and feels great, but it's shady. I keep getting a "bad login" error and so can't do anything other than just read. Whatever it's doing for an internal Web View seems to be a part of the issue as when I tried to sign in with Google through that I got a page saying it's an insecure browser. So, that's interesting, and I won't be reinstalling.

Recently the comments have stopped loading. The following error occurs. Loading failed AP| Server error: This is most likely due to the Algolia Hacker News API which Harmonic uses being down. Historically outages for the Algolia AP| are limited to a few hours, but they can last longer. Prior to this the app was excellent. How to revise this back up to five. Wish there been a more ready way to report bugs.
