The problem
The group chat falls apart the moment the trip begins.
Planning a trip with friends or family means a pile of texts, screenshots, PDFs, and half-remembered reservations. The second you leave home, all of it goes stale.
That One Time collapses all of it into one source of truth that updates for everyone, instantly.
- “Wait — which restaurant did we book for tonight?
- “Did anyone actually reserve the tour, or…?
- “Can someone re-send the address? I lost it in the chat.
- “Whose phone has the good photos from day two?
Why people love it
Built to be the guide you actually use on the road.
Not a planning tool you abandon once you leave home — the one app the whole group opens all trip long.
Real-time, always
An edit on one phone is on every phone. No more “which version is current?” — everyone sees the same plan, the moment it changes.
Private by default
Every trip is gated to its members, with revocable read-only links for grandparents and friends who just want to follow along.
One tap to the next thing
Directions, call-to-book, add-to-day, save-photo — each is a single tap. Nothing buried in menus when you need it at 65 mph.
Everyone’s in sync
Two families, three cars, kids in the mix — one shared plan keeps the whole party moving together without a dozen “where are you?” texts.
The album everyone keeps
Photos and clips fill the shared Memories tab as the trip happens — auto-tagged to the day, grouped by place, saved back in a tap.
In English and Spanish
The app follows the phone it’s already on, and you can switch any time. Two people on the same trip can each read it in their own — the plan is shared, the words around it are yours.
What’s inside
One shared app. Zero group-chat chaos.
Everything the trip needs, in one place everyone can see and edit.
One living plan, current every day.
Open to the day’s plan and what’s next — your lodging, a tap-to-navigate address, and the day at a glance. Reorder activities, edit times, and weave in flights and drives; everyone sees the change the instant it happens.
Find the good spots, keep the moments.
Search for a place and save it to the trip — then drop any of them onto a day. Everyone’s photos land in one shared album, auto-tagged to the day and saved back in a tap.
A highlights story, auto-made when the trip ends.
That One Time assembles a shareable recap — a cover, the numbers (days, places, photos), and a day-by-day story of where you went and the moments you caught. A link you can send to family who weren’t even there.
How it works
From scattered chat to shared guide in minutes.
No setup headache, no learning curve — and nothing for the people you invite to install.

Travel together, live
Everyone adds places, checks off bookings, and drops photos — all syncing in real time. The plan stays current without a single “what’s the plan?” text.

Frequently Asked Questions
What is ThatOneTime?
ThatOneTime is a real-time, shared trip guide that lives on every traveler's phone. Plan the trip together, watch it update for everyone instantly, and keep all the photos in one shared album. Get it free on the App Store or Google Play, or use it right in the browser — either way, anyone you invite joins straight from a link.
Is ThatOneTime available in Spanish?
Yes — the whole app is in English and Spanish, and it follows your phone's language automatically. You can switch it any time, before or after you sign in, and emails come in your language too. What your group writes — trip names, notes, captions — stays exactly as they wrote it; we translate the app, not your trip.
Is it free?
Yes — you can start a trip free with Day Trip (up to 2 travelers). Bigger trips are a one-time price per trip: Getaway $2.99 (up to 8), Adventure $4.99 (up to 12), and Big Trip $12.99 (up to 20). Only the trip organizer pays; everyone else joins free.
Do my travel companions need to pay or download an app?
No. The iPhone and Android apps are free if they want them, but nobody has to install anything — a link opens the trip in any browser, and it installs to the home screen like an app. Only the trip's organizer pays to start the trip; everyone else joins free.
How do I sign in?
With just your email — we send a magic link or a 6-digit code, so there's no password to remember. Prefer a password? You can set one as an option.
Can everyone add photos?
Yes. Everyone's photos land in one shared album, automatically grouped by day, and you can download all of them anytime for free. When the trip ends, ThatOneTime builds a shareable recap you can send to anyone.
How many photos can we add?
Every traveler gets 100 photos in the shared album, and anyone can unlock more for their own photos whenever they want. Events give each guest 50.
