01Overview

A self-initiated concept, designed like a real product.

The brief we set ourselves

Design one place where a group of friends decides dates and places by voting, builds a shared day-by-day plan and settles who owes whom — so the group chat can go back to memes.

Who it is for

Friend groups aged 22–35 planning weekends away, bachelor(ette) trips and festivals; the one friend who always ends up organising.

What we designed

Trip home with a countdown and a live poll, a vote with date windows and swipe cards, a shared itinerary with an empty slot, and the money screen with balances and settle-up.

Design facts from the concept files — not business results.

02Research

Friends plan trips together — in tools built for one.

We checked how many people actually travel in groups, which startup trend the scenario belongs to, and where today's trip planners stop being enough.

We checked how many people actually travel in groups, which startup trend the scenario belongs to, and where today's trip planners stop being enough.

  1. Behaviour

    About one traveller in five plans trips with friends, and among Gen Z it is a third (Booking.com trends for summer 2025).

    DecisionMake the crew the main object of the app: avatars on every card, «4 of 6 voted», tasks and balances per person.

  2. Trend

    Y Combinator's Fall 2026 Requests for Startups include «Multiplayer AI» — products where several people act on the same thing at once.

    DecisionDesign every screen as multiplayer: live poll results, «3 said yes» on a card, an empty evening slot that starts a vote for the group.

  3. Gap

    Itinerary planners such as Wanderlog are strong on routes, but voting and cost-splitting usually live in separate apps like Splitwise.

    DecisionVote, Plan and Money as three tabs of one trip, sharing the same people and the same days.

Patterns we borrowed

Wanderlog
Only the scenario — a day-by-day plan; no screens or visuals audited or reused
Dating apps
Swipe cards for places: no / yes / maybe instead of a long comment thread
Poll widgets
Live percentages and «4 of 6 voted» right on the option
Bill splitters
Balance chips per person and the minimum number of transfers to settle up

What we left out

Logos, screens and copy of Wanderlog, Splitwise or any travel brand. Crewtrip has its own mark and its own photos; venue names in the screens are invented, not partners.

03Before → After

From a list of decisions to a trip the crew wants to open.

Every «before» is generated from the very same screen markup, reduced to outlines, readable labels and grey word-bars — no colour, photos or glass. Drag a handle to compare.

  1. 01

    Hierarchy

    The countdown and the crew first, then the one open decision («Where do we eat Friday?») — the home screen always asks the group something.

  2. 02

    Postcard layout

    A full-bleed photo top with a glass card over it on home and vote; calm sand cards for the plan and the money, where people read numbers.

  3. 03

    States

    Voted / not voted, a top-voted event, a swipe stack with no / yes / maybe, an empty evening slot with «Add place / Start a vote», settled and open transfers.

  4. 04

    Assets

    Four photos made for the concept — the crew on the cliff and three place cards. UI stickers and stamps instead of drawn illustrations.

  5. 05

    Glass, measured

    White 60% glass with 30 px blur and a dark scrim under the status bar. Worst pixel under any glass text: 4.61:1.

  6. 06

    Real-looking data

    Six friends with initials, a ferry booked at 08:40, €2,184 spent in 23 expenses, three transfers to settle — realistic lengths everywhere.

04Brand system

Lagoon for decisions, sun for the fun part.

Lagoon teal carries every action (6.1:1 with white text); sun yellow is the holiday accent at 1.74:1 on sand — stickers, badges and highlights with dark text, never text on its own. Syne gives the headlines a postcard swagger; Manrope keeps times and money readable.

Crewtrip

A lagoon «C» ring and a sun «T» whose crossbar becomes an arrow — movement, travel. Picked from four sketched directions because it reads at 16–32 px without tiny figures.

The crew on the coast, a glass card with «12 days to go», six avatars and «Villa booked», and a live poll for Friday's dinner.

Day 2 as a timeline with weather, bookings and the top-voted sunset — and an empty evening that offers to add a place or start a vote.

Money

Trip total, a balance chip per person, the three transfers that settle everything and the latest expenses.

Crewtrip — detail: Balance chips
05

Balance chips

Plus or minus per friend, in colour and in sign — readable without the colour.

06FAQ

Questions & answers

Is Crewtrip a real product?

No. Crewtrip is a self-initiated concept by Omnisense — a brief we set ourselves, with no client and no business metrics. All people, places, bookings and amounts in the screens are sample data; venue names are invented, not partners.

Who is Crewtrip for?

Friend groups aged 22–35 planning weekends away, bachelor(ette) trips and festivals — and the one friend who always ends up organising.

What problem does it solve?

Group trips usually get decided in a long chat. Crewtrip puts voting on dates and places, a shared day-by-day plan and who owes whom in one place: Vote, Plan and Money as three tabs of one trip, sharing the same people and the same days.

What did you design?

Trip home with a countdown and a live poll, a vote with date windows and swipe cards, a shared itinerary with an empty slot, and the money screen with balances and settle-up — plus a component sheet, logo, palette and type system.

Are the photos stock?

No. Four photos were made for the concept — the crew on the cliff and three place cards. UI stickers and stamps are used instead of drawn illustrations.
