Tripfold for iPhone, in TestFlight beta

Your whole trip, offline.

Itinerary, city guides, maps, currency, flights and travel documents in one app. It works in airplane mode, in a dead zone, and when you are saving roaming data abroad. No account, no tracking, your data stays yours.

Tripfold's Today screen: the current day of a trip with the hotel, plan and warnings. Tripfold's Cities screen: a city guide with a map and nearby places.

What it does

The day you are actually in

Every day laid out with times, plans and the city you are in, and a Today view that surfaces what is happening now. Swipe to tomorrow to see the thing you need to decide today.

City guides worth reading

A short history of each place, tipping norms, getting around, emergency and nearest-medical contacts, restaurants with the dish worth ordering, and the local specialty with the best place to try it.

Maps that work with no signal

Curated map highlights for each city offline, live category search around your stay when you do have a connection, and one tap to walking directions.

Flights and bookings

Every leg with times and aircraft, live status a tap away, and your confirmation on a stub card. Where the issuer gave you an e-ticket, its real scannable barcode is attached, never one the app drew itself.

A documents vault

Scan and store passports and travel documents on your device only, behind Face ID, encrypted at rest, never sent anywhere.

The practical stuff

Offline currency conversion with a manual rate override, one-tap copy for any address or confirmation code, a prep checklist, your own notes, and an eSIM setup card.

A look at it

Private by design

The app is built so that I cannot see your trip.

There is no account and no login. No third-party analytics, advertising or tracking; the app uses Apple frameworks and nothing else. It never asks for your location. Optional sync is end-to-end encrypted and zero-knowledge: your trip is encrypted on your device with a passphrase only you and the people you share it with know, and you can host it anywhere, because the server only ever holds ciphertext. Passport details stay in the Keychain and the encrypted vault, and are never networked. The full detail is in the privacy policy.

Try it

The beta is open.

Tripfold is in public TestFlight beta. Tap the button on your iPhone, install Apple's TestFlight app if you don't have it, and you're in — no signup, no email, nothing to create. Load the sample trip to poke around, build your own, or point it at a trip you host yourself. If something reads wrong or breaks on your device, the feedback button inside TestFlight goes straight to me.

Built because our family travel doc kept falling apart.

It always failed in the same place: a train station in a country whose language we did not speak, with no signal and a confirmation code somewhere in a thread. I wrote about turning that mess into a real app, and about what the build taught me.
