Sam can’t make it
One tap on “I can’t make it”, from the app or straight from a texted link. No sign-in.
The right cooks are asked
Everyone who can cook that shift gets one push. Anyone without the app gets a text, if they said yes to texts.
Alex takes the shift
One tap on Request. On Pro, the first good fit takes the shift on the spot.
You wake up to it done
One notice, “A call-out was covered”, naming who took it. The board already shows it.
