Send when they can hear it
You write what you mean — in a soft, single composition, not a feed. As you type, the app can gently offer a kinder way to say the same thing, built from your own words. Nothing sends unless you choose it.
Then you decide when it arrives: send now, schedule for the morning, or wait until your partner signals they're open. The hard message you wrote at 11:43 PM doesn't have to go out at 11:43 PM.
