All I Need

Packing is not a memory problem

It is a maths problem with a weather forecast attached. So the app does the maths and reads the forecast, and hands you a list that is already right.

It knows how many

Every item carries a base rate, a spare, and a ceiling. The ceiling is the part most packing apps miss. Without it, a twenty one day trip asks you for twenty one pairs of underwear.

Trip length5 days

Underwearceiling× 6

Teesceiling× 5

Trousersceiling× 2

Socksceiling× 6

Drag it past three weeks and watch the ceilings hold.

It knows what you forget

Twelve rules run against the real forecast and against what you have already packed. Eight read the weather, four read the trip itself. At most five surface, ranked by severity, each once. A rule stays silent if a list you chose already covers it.

“Down to 2° at night.”

“The United States uses Type A and B plugs.”

It knows nothing about you

No account, no server, no analytics in the app. There is nothing to sign up for and nothing to leak, because nothing goes to a server of ours. Sync, when you turn it on, runs through your own iCloud or Drive.

Works offline. Everything except the forecast, and the last one fetched is shown with its timestamp.

What the forecast actually tells you

Six of the twelve. Each one waits for a condition, suggests a few things, and says one short sentence. It appears once. Wave it away and it stays away.

When	It suggests	And says
rain ≥ 40% any day	Umbrella, rain jacket	“Rain likely on 3 of your 5 days.”
max ≥ 38 °C	Rehydration salts, bottle	“Extreme heat. 39° on Thursday.”
min ≤ 5 °C	Warm coat, gloves, scarf	“Down to 2° at night.”
daily range ≥ 15 °C	A layer you can take off	“18° swing between day and night.”
any flight ≥ 6h	Neck pillow, eye mask	“A nine hour flight.”
trip ≥ 10 days	Laundry pouch, detergent	“Ten days. You will wash something.”

Built twice, on purpose

Most apps that run on both phones are built once and dressed twice. You can always tell. This is two apps that agree on everything except how they look.

Liquid Glass, all of it

Apple's current design language, used the way Apple's own apps use it. The layer you move through is glass. The layer you read stays paper. Toolbars float, bend what scrolls beneath them, and shrink as you go.

We wrote no custom bars, because the system draws better glass than we could.

It needs iOS 26. Your phone has been waiting for a reason to show that off.

Material 3 Expressive

Not the iPhone app with the corners changed. Google's current design language on its own terms: its own shapes, its own motion, its own way of showing you what just happened.

The two apps share a palette, a type scale, a data model and the engine that works out your quantities. They share no chrome at all.

Android 12 and up, and everything above it gets the full treatment.

There is a reason to care beyond taste. An app built in the system's own language inherits the system's own work: the animations you already know, the gestures your thumb already expects, the accessibility settings you already set. Hold one in each hand and only the icon gives it away.

One app, every climate

There is no home market. Units, currency, date format, week start and temperature follow your device on first launch, and all of them stay changeable.

Celsius or Fahrenheit, whichever your phone already uses. You never set it.

Your first trip is free. Every trip after that comes with Pro.

The free trip is the complete packing app, not a demo. Every built in list, fully editable, with weather, advice, the departure countdown and the widget. It stays yours to read after you come home. What you pay for is every trip after it, not a better app.

There is no server. Nothing is stored with us.

Which means there is no account to create, no password to lose, and no database of your travel plans sitting anywhere. Sync means your Apple devices together, or your Android devices together, through storage you already own. It copies your trips and your lists, never the weather it downloaded or the settings on the device in your hand. iPhone to Android is deliberately out of scope, because doing it properly would mean a server, an account and a privacy policy, and would cost the app the one thing worth advertising.

Read the full privacy page for exactly what is sent, when, and to whom.

Close the bag with confidence.

Your first trip free, every feature included. Decide after that.

Made by

All I Need is the first app from dymn, a company of seven developers spread around the world, building small single purpose apps for things people do every day.

The rules are the same across all of them. One payment, never a subscription. Nothing collected. An app that does one thing and then gets out of the way.
