Carry-On Ready

Carry-On Ready is a constraint-based packing calculator for long-term, carry-on-only travel. Instead of generating a generic packing list, it estimates whether your gear actually fits inside your bag volume based on climate, trip length, laundry access, workload, and personal constraints. It assigns realistic liter values to common travel items and shows how close you are to capacity in real time, separating recommended items from optional add-ons so you can pack intentionally instead of optimistically. Built for one-bag travelers who want to pack lighter without guessing.
