Lume is a car cost tracker built around a two-second glance. You log fill-ups, tolls and services on the phone. Three small widgets do the rest — on the Home Screen, in StandBy, and on the iOS 26 CarPlay dashboard.
Fuel, tolls and service divided by the miles you actually drove.
Dimmed, red-shifted at night, readable from across the room.
Sits beside maps and music. Never asks you to tap while driving.
One email when Lume hits the App Store. Nothing else, ever — and I don't keep the list afterwards.
