TIMELINE
6 months

Coordinating travel with friends can quickly become a stressful experience. The joy of the trip is often overshadowed by the complexities of planning — and the process can feel overwhelming and take away the excitement of traveling together.

Why this matters

A long-running Harvard study on adult development, summarized by its current director Robert Waldinger, found that strong social connections are one of the most significant contributors to long-term happiness and health. (Mineo, 2017)

35%

Post-covid, we are noticing a strong resurgence of group traveling, with a 35% rise in bookings for groups of eight or more, as people increasingly seek meaningful shared experiences - whether through multigenerational vacations, food-focused trips, or outdoor adventures (Apse, 2025).

What tools are already out there

I conducted a heuristic analysis of popular trip planning tools to evaluate how well they balance customization, information hierarchy, and user engagement. I focused on four key heuristics:

  • Visibility of system status

  • User control freedom

  • Flexibility + efficiency of use

  • Visual design

Key Observations

Icon of a lock

Apps like TripIt and Wanderlog gate features behind early paywalls, discouraging users from completing onboarding.

Black and white icon of three horizontal sliders with circular knobs.

Excessive customization and feature options lead to decision fatigue, slowing down the planning process.

Icon of a smartphone with a calculator app open.

Tools like Excel and Google Sheets prove effective for trip planning, leveraging existing mental models.

What I wanted to know from users

1

What tools/methods do people currently use to plan group trips, and what aspects of those tools work well or fall short?

2

What factors do people consider when determining if someone is a good travel companion?

3

How do people perceive and experience shared decision-making when planning trips with friends?

4

What pain points or challenges are commonly overlooked when planning trips with friends?

What users shared

I surveyed 26 participants to capture quantitative data on travel habits and the pain points of group coordination. From there, I conducted 5 in-depth interviews focused on recent or upcoming trips to understand planning behaviors, tool usage, and key friction points.

A digital planning board with sticky notes and sketches organized into sections. The notes cover topics related to travel, planning, decision-making, and sharing resources, with themes such as major hurdles, tools used, and travel tips.

What themes emerged

Recurring themes emerged as I created this affinity map.

  • Challenges Accommodating Different Preferences

  • Lack of Equal Contribution/Input

  • Distrust of Online Sources

  • Managing Budget Constraints

  • Existing Decision-Making Tools/Methods

Quote about opinions and restrictions: 'The more strong opinions there are, the more restrictions there are - the easier it is to actually make an executive call.' - Harsha, Female, 27

OPPORTUNITIES

How might we make it easier for everyone to communicate their preference and expectations early in the planning process?

How might we ease the burden on group planners by distributing tasks and decisions more collaboratively?

THE CONTRIBUTOR

THE PARTICIPANT

  • Overwhelmed by too many notifications.

  • Doesn't want to plan every detail.


  • Keep up with essential details only.

  • Get notified when input is needed.

User Flows

I designed the user flow around two core experiences: account creation that captures travel preferences upfront, and trip creation that facilitates early alignment and group input.

Flowchart titled 'User Flow 01 - Create an Account' showing steps for creating a user account, including start, splash screen, profile creation, login options with phone/email or social media, and dashboard.
Flowchart titled 'User Flow 02 - Create a Trip' illustrating steps for creating a trip, including creating a new trip, adding dates, location, friends, and preferences, and then adding activities like hotel and flight.

Mapping the screens

Used low-fidelity wireframes to establish structure and validate early solutions.

Curating the visual identity

Momentr reimagines group travel planning as playful and collaborative, moving beyond spreadsheets toward a dynamic, visually rich experience. Drawing from scheduling app layouts and poster graphics, the design feels expressive, intuitive, and designed to build excitement.

The typography section lists font sizes and styles for page titles, section titles, headers, input text, and body text. The action styles section shows buttons for past, upcoming, and disabled states, and navigation icons for unselected and selected states, with sample labels. The design elements section displays large and small corner radius rectangles. The color palette includes soft white, persimmon orange, true blue, chartreuse yellow, electric green, additional true blue and soft white circles with hex color codes, and persimmon orange circle.

Personalized travel profile

Users begin with a travel quiz to determine their archetype. These insights inform personalized planning, highlight travel compatibility within the group, and help establish alignment from the outset.

Empowering personal input

To establish clear preferences early, users are prompted to select their top priorities and activities before moving forward with planning.

The cover features icons of friends chatting, beverages, a globe, a person taking a photo, sunglasses, an airplane, and a bowl of ramen, all over a background of a traditional Japanese temple.

AI-generated vision board

To maintain alignment throughout planning, I introduced an AI-generated vision board that aggregates the group’s preferences into a vision board. The visual updates dynamically as members join and is anchored at the top of the dashboard to continuously reinforce the group’s shared goal.

Assigned Tasks

Present individually assigned tasks in a visible way to increase transparency around upcoming decisions and ensure all members can contribute feedback.

Testing with real users

  • Is onboarding clear and engaging?

  • Are collaborative features intuitive?

  • Can users easily set preferences?

  • Are key details visible and accessible?

  • Does the experience feel valuable?

Here's what I asked them to do

  • Complete onboarding by creating a trip profile.

  • Create a new group trip.

  • Complete your assigned tasks

  • Add a poll to the group trip. 

What I learned from users


While this version shows the breakdown of the cost, Users wanted more opportunities for personalization and customization.

Users paused to understand how to begin or complete the task due to a lack of clear entry points.

Users expected poll creation to occur on this page.

Each screen required tapping the next arrow, which created unnecessary friction and slowed down the flow.

How I updated the design


I enabled manual budget calculation so users could define realistic spending limits.

To reduce friction and help users get started, I opened the first task by default.

A clear CTA was added to the bottom to support creating a new poll.

I built momentum by automatically progressing to the next page when users select their answers.

Closing Thoughts

  • Group decision-making proved more nuanced than I anticipated; balancing diverse travel preferences and personalities required thoughtful, deliberate design choices.

  • Users strongly resonated with personal travel profiles, allowing opportunities to explore compatibility matching and strength-based task delegation in future iterations.

  • Customization requires balancing flexibility with simplicity to prevent cognitive overload. Future iterations could introduce a more robust onboarding experience to gradually educate users on the platform’s full feature set.
