New:
- Updated touch gestures on maps, and more accurate travel times.
- Bug fixes to activity times and shared links.
- Tour Group hosts up to 50 travelers.
That One Time replaces the messy group chat with one shared, living guide — for road trips, weddings, reunions, and every "remember that one time…" in between.
"Wait — which restaurant did we book for tonight?" "Did anyone actually reserve the tour, or…?" If your group trips live in a 400-message thread, this is for you.
ONE PLAN, EVERY PHONE
Build the itinerary together — days, activities, travel legs, and where you're staying. Any edit from any phone updates for everyone, instantly. No refresh, no "check the latest version."
TODAY, AT A GLANCE
The app opens to today: where you're staying, what's planned, and one tap to Maps for whatever is next.
PLACES WORTH KEEPING
Save restaurants, beaches, wineries, museums, and day trips. Paste a Google Maps link and the details fill themselves in. Tap a place to drop it into any day.
THE ALBUM EVERYONE KEEPS
Photos from every phone land in one shared album, grouped by the day they were taken. Like them, comment on them, and download the whole set when you're home. No more "can you send me those pics?"
EVENTS, TOO
Weddings, parties, reunions — give every guest one page for the schedule, the venue, and a shared album that fills up as the night happens. When it's over, the album settles into a recap.
INVITE IN SECONDS
Send a link or show a QR code. They tap it, they're in. You choose what each person can do: help plan, add photos only, or just follow along. Hand someone a co-host role and they can run the trip alongside you.
STAY IN THE LOOP
Get notified when someone adds photos, changes the plan, or replies to a comment — grouped rather than one buzz per tap, and switchable per trip.
THE RECAP
When it's over, That One Time turns the whole thing into a highlights story you can share — the plan, the places, and everyone's photos, day by day. Send it to the people who weren't even there.
BUILT FOR THE GROUP
Now in English and Spanish, following your device's language. Works on iPhone and iPad. The plan is cached on your phone, so you can check tonight's booking with no signal. Signing in is passwordless — enter your email, tap the code, you're in.
Your trips are private to the people you invite, and your photos stay yours. Anything that shouldn't be there can be reported in a couple of taps.
That one time you all got away? Keep it.
Found this app and used it on a trip recently and so helpful! Really helps to keep the trip organized. Before and after. App is probably mostly used for planning, but I also loved it to look back and remember what we did each day. Would definitely recommend the app if you are traveling with another group. Or even a couple, both adults can get the app and stay on the same page. Recommend trying👍👍👍👍👍
Perfect for Keeping a Group Trip Organized

I used That One Time to coordinate a trip around Oregon with several stops. My guests were coming from out of town, so I wanted to have everything planned and make sure everyone knew where to go. The app made it easy to keep the whole group on the same page throughout the trip. I also loved that everyone could post their photos in one place—no need to keep asking each other to share them afterward!

A very useful and easy app that you can instantaneous share with family and family during your trip or adventures. Family and friends can vicariously be with you on your trip or travels! I used it with my trips and family gatherings or reunions! Love it!
Smoother day map, and times you can trust.
- Drag the day map with one finger — no more two-finger wrestling
- The map opens faster
- An activity's time now sticks when you set or change it
- Travel times are honest: when there's no transit between two stops we say so, instead of showing a walk under a train icon
- A share link opened while you're signed out takes you to Join, not a "Private trip" dead end
