I'm really impressed by the attention to detail for a brand new product.

I know they spent a couple years getting to this point, but I can really appreciate the quick, well-designed iOS app, and the native, non-Chromium / non-Electron Mac app that only uses 35MB of RAM and has no noticeable idle CPU draw. It's such a stark contrast with Slack and most of today's pseudo-native apps.

Impressive launch!
