By using Noor you actually spend *more* time being focused.
Because in a typical voice chat, you get what you need in under 10 minutes whereas it'd be text messages scattered over >1 hour, basically keeping you out of deep flow not knowing if you will get an answer or not.
You'd still use async messages for most things. Point is some stuff really need high-bandwidth back and forth chatting: getting help in code, feedback on an early design, syncing with a teammate, or asking a blocking question. In these scenarios, texting hurts your team's focus.
