Packing · plan · weather · works with no signal
A packing and itinerary companion for you and whoever you travel with. It watches the forecast, knows how high you are going, and keeps working when the signal doesn't.
The trip it was built for
Why it exists
Nine days from Delhi into the Spiti Valley and back: Shimla, the apple orchards of Kinnaur, then the road tips over into cold desert. Tabo, Kaza, and the high villages above 4,400 m — Komic, and Hikkim, where there is a post office you can mail a postcard to yourself from. It arrives weeks after you are home.
Two people packing for that is genuinely hard. You need a down jacket you will not touch for four days, and a headlamp you will need at exactly one campsite. Half the kit is shared and should only be carried once. A spreadsheet handles none of this, and phone signal disappears on the day the packing matters most.
So the trip became the spec. Everything here exists because something on that road needed it.
Packing
Every item carries tags. When the forecast for the day drops below 5 °C or the leg sits above 4,000 m, the down jacket, thermals and gloves move to the top of the list on their own. Rain over 50 % pulls the cover out. UV over 6 pulls the sunscreen.
temp_min < 5 °C · altitude > 4,000 m → cold
Your people
Invite up to three others by link. Every item belongs to one person or to everyone: personal items track a packed state each, shared items track one between you. Check something off and it lands on their phone in under a second.

Offline
The pack list, the plan and the last known forecast stay readable with the radio off. Check-offs made without signal queue on the device and sync themselves the moment a bar comes back.

Pemba
Ask what to carry tomorrow and Pemba checks the real itinerary, the live forecast and what you have already packed before answering. It can add items too — but every write stops at a confirmation sheet first.
Never prescribes a dose. Altitude sickness questions go to a doctor.
Bring your own key
The AI guide is the one part of this that costs real money per message. This is a side project from one trip, so it cannot pay for everyone's conversations — and an app that quietly burns someone else's credits is not one worth publishing.
Add a key in Settings whenever you want it, and pick the model you pay for. Everything else works without one — the pack list, the plan, the offline sync, the weather, and importing an itinerary from a PDF or a link, which is read by rules on your own device rather than by a model.
The whole thing is open source — schema, offline layer and all. Fork it for your own route, or make an account and try this one.
