A closer look at the app

PackNinja does the remembering: what the weather calls for, how many shirts a week needs, which plug fits the wall, and what you forgot last time.

AI Suggestions screen listing gloves, a beanie and a scarf, each with a reason, and an Apply All button

AI suggestions that explain themselves

Ask for suggestions and PackNinja looks at the destination, dates and forecast, then proposes items you haven't packed yet, grouped by category.

Each suggestion says why it's there, like gloves because evenings drop to 2°C.
Items already on your list are skipped.
Add them one at a time, or all at once.
Free accounts get 10 requests a month; Pro is unlimited.

Add buffer items so you're never one sock short.
Turn rules on or off as your trips change. Custom rules are a Pro feature.

Questions

Something else? Get in touch.

Is PackNinja on Android?

Not yet. PackNinja is for iPhone and iPad running iOS 18 or later.

Do I need an account?

No. Your lists are stored on your device. If you're signed in to iCloud, you can turn on iCloud sync to keep your devices in step.

Does it work offline?

Yes. Your trips, lists and templates are all on your device. AI suggestions, AI covers and weather updates need a connection.

How do AI suggestions work?

PackNinja sends the trip's destination, dates, forecast and current list to a language model (Google Gemini) through our server, then shows you the items it suggests and why. Nothing is added until you choose.

How many AI covers can I make?

Free accounts can generate 3 AI trip covers a month and Pro accounts 60. The count resets each calendar month. Using your own photo doesn't count.

Who can see a list I share?

Only people you send the link to. You choose what to include (packing items, to-dos, notes, location), and the link opens a copy of the list in PackNinja.

I use PackNinja on two devices. What should I know?

Keep the app updated on both so they sync the same way. If you turn on iCloud sync, sign in to the same Apple Account on each device.

Which languages are supported?

English, Japanese, Korean, Simplified Chinese and Traditional Chinese. The app follows your device language, and you can choose the language of the built-in items in Settings.
