It does not make packing lists. It makes sure you are ready to leave: weighed bags, the weather checked against the list, and what is still missing on your home screen.

Open a trip, tap Share readiness, and pick a card. Field Manual has a passport stamp, a boarding pass and a luggage tag. Aurora has the number, the ring, and one block per item.
Trip Readiness now comes in Extra Large. On iPad it is the wide one: your dashboard on the left, a progress bar for every category on the right, so a glance says which part of the bag is behind. On iPhone with iOS 27 there is a tall one too.
Pro now shows its meter. Account says how much of the month's scanning allowance is left and when it resets, and a Scan Pack tops it up for $1.99 if you run out first.

Slide it open to find everywhere you have been, everything you carried, and what actually happened.
A charger you need tonight is not unpacked, it is Pack Later. An adapter you have not bought is Need to Buy. Both count honestly, and Pack Later items rise to the top on the last day.
Five sizes, each a different widget rather than one at five scales, up to Extra Large on iPad. Tap the circle beside an item to pack it without opening the app.
Three cards drawn from your counts and your weight, light or dark, post or story. Your numbers go out, your items never do.
Sort items into carry-on, personal, and checked bags, and watch a live gauge keep you under your airline's limit.
See the temperature, meaningful weather, daylight, local money, plug type, voltage, and what is still missing.
Every trip is scored on weight discipline, readiness, and bag limits, with specific ways to pack lighter.
See every trip as one route on a real map, a fitted route chart, or a globe you can spin.
Keep a dated diary with photographs, because the useful parts of a trip begin after the list is finished.
Keep boarding passes, bookings, photographs, and every page of a PDF private to your account.
Pack from photographs with backgrounds removed on your device, in My Gear and directly inside a manifest.
Earn the same travel marks as enamel pins you can turn over or stamps in a passport you page through.
Leaderboards are off until you opt in. Stay private and your personal Service Record still keeps the same numbers.
Everything you carry except what you wear. The Packing Index tracks base vs wearable weight automatically and scores each trip on an ultralight scale.
Draft from your destination and dates, or photograph your gear laid out flat. Tactical Scan identifies each item with an estimated weight, and you approve everything first. Scanning is part of Pro.
Give any bag a limit and a live gauge shows exactly how far under or over you are as you pack.
Where you are going, how ready you are, how soon you leave, and what to do next. Up to Extra Large on iPad, with a progress bar for every category.
The app is free on iPhone, iPad and Mac, and at packingindex.com, with trips synced between them. Trips, manifests, gear, bags, templates, the catalog and the Loadout all stay free.
A membership for the parts that cost real money to run: the AI gear scanner, weight lookup, the Trip Readiness widget, and adding documents to the Dossier. Monthly or yearly, and the yearly plan starts with a free trial.
Free on iPhone, iPad, and Mac. Pro is optional.
