Every time I either open all my feeds or the Hackaday feed in particular, the iPhone app suddenly goes to a black screen and then back to my home screen. I can trigger it consistently, and it doesn’t seem to do it for other feeds. I’m on an iPhone 7, iOS 11.2.5
Thank you so much for reporting this! I just found the issue and it looks like the fix will make scrolling the story titles list a touch more performant. The issue was improper decoding of HTML entities as Hackaday uses some special encodings that I don't often see. I'll push it to the app store later this week.
