Every parent knows the drill: shoes are missing, someone needs to pee again, and the one who was ready five minutes ago is now naked. You can't control all of that. But you can start the sequence early enough that there's room for it.
Adults underestimate kid-time by at least 50%. Getting dressed isn't 5 minutes. It's 5 minutes of finding clothes and 10 minutes of convincing someone to wear them. Breakfast isn't 10 minutes. It's 10 minutes of eating and 5 minutes of cleaning the cereal off the floor. Backward planning only works if the durations are honest.
Instead of one alarm that says "leave now" (which is already too late), Ready Time sends a notification for each step. Wake them at 6:50. Clothes at 7:00. Breakfast at 7:15. Each tap is the next thing that needs to happen. You follow the sequence instead of tracking it in your head.
