Tagalong

Started life as Collab Trip Planner.

One person plans the trip; everyone else just needs to know when to leave, where to go and what to bring. Tagalong turns the plan into a single route with “up next” always on top and the must-knows in marker yellow, so nobody gets to say “well, I didn’t know.”

Tagalong on a phone, with sample data: “Salir 9:05 AM” for a kayak tour, must-knows “Bring swimsuits” and “4 seats · KAY-2081” in yellow, and the day’s route below.

The good parts.

Up next, front and centre

The next time-bound stop surfaces by itself, with the leave-by time, drive time, tickets and what to bring.

Paste the group chat

Messy WhatsApp or iMessage threads in mixed Spanish and English become activity cards, never translated or “corrected”.

Loose plans stay loose

Option stacks you swipe through, plus TBD and “maybe” as first-class states.

Share a link, no accounts

Separate viewer and editor links, offline access, and edits from two phones merged stop by stop.

Under the hood.

One orange route, stops circled on it, must-knows in marker yellow. Checked for WCAG 2.2 AA and pixel parity with the original prototype.
