Yes, SPAs are absolutely horrid. I tried to use HEY Calendar and the iOS app is just so absurdly slow I went back to the native iOS calendar app.

Maybe it speeds up their dev time but a native app should not feel like a (poorly engineered) web app. Every click loads for a second or two and sometimes it hangs for even longer. I grew to dread adding and managing events.

It’s a shame because even though the app made some questionable design choices, it was in general a breath of fresh air in terms of UI.

I’d like to hope that they’ll fix it, but I know they won’t.
