A family trip planner that works on the plane.
The moment the wi-fi drops is often the moment you need the itinerary. Offline is not a niche; it's the correct default for travel.
Trip-planning apps have discovered that they sit in a spot where you'll pay them per year to remember your booking confirmations. A file per trip does the same thing — and unlike the app, it opens on the plane.
One file per trip
Itinerary, packing lists per traveller, budget, booking references, phone numbers, addresses, and the local emergency numbers. All in one file.
Print the itinerary
The printed copy is the one that still works when the phone battery is 4%. HTML prints cleanly, deliberately.
Kept as a memory afterwards
Rename the file, drop in the photos and the postcards, and the planner becomes the trip journal. Same file, second life.
What to reach for
Common questions
Bookings?
Paste the confirmation into the file. Screenshot the QR code. The airline app is fine as backup; this is the primary.
Multi-family trip?
Share the file. Everyone gets the same itinerary.
Maps?
Save offline maps in your map app. The planner links to them, not the other way around.
After the trip?
Turn it into a journal entry, or archive the file with the year's photos.
