Making Plans

Shouldn’t Feel

Exhausting

Planning simple meetups slowly became emotionally draining.


Too many chats, unanswered messages, changing schedules,

and constant coordination turned spontaneous plans into effort.


The challenge wasn’t meeting people,

it was coordinating them effortlessly.

Coordination was spread

Coordination

was spread

across

too many places

Conversations happened in WhatsApp.

Dates lived in calendars.
Locations were buried in chats.


Responses were impossible to track.

Nothing was centralized, making even

simple plans hard to manage.

People weren’t struggling to socialize

they were struggling to coordinate.

The experience needed to feel lightweight, natural, and instant while still helping users organize people, time, and decisions effortlessly.

Existing Tools Weren’t Built

for

Spont neous

Social Planning

Most existing platforms focus on messaging, scheduling, or event management separately forcing users to jump between multiple apps just to coordinate one simple activity.


While these tools are powerful individually, none were designed around lightweight, real-time social coordination.

The problem wasn’t communication

it was fragmentation.

Why Planning

Why Planning

Exhausting?

To better understand why casual plans often fail, I conducted user research focused on social coordination habits, communication patterns, and decision-making friction.


The goal wasn’t to study event management but to uncover why spontaneous plans become overwhelming so quickly.

Planning looks different for every person.

Some struggle with coordination, others with decision fatigue,

From rough ideas

to

structured experiences

Before moving into polished interfaces, I explored multiple interaction patterns through fast hand-drawn sketches.


The goal was to quickly test different flows, screen hierarchies, and social coordination behaviors without getting distracted by visuals too early.


These early explorations helped define the core structure of the app from activity creation and response timing to live coordination and group interactions.

Early concepts explored:

Activity creation flow

RSVP interactions

Response timer mechanics

Group coordination patterns

Navigation hierarchy

Solo vs group activities

What this project taught me?

1

Designing for real human moments

Not every product solves productivity problems. Some products exist to strengthen connection, belonging, and presence between people.

2

Simplicity creates emotional clarity

Reducing friction wasn’t only about UX it was about making social interaction feel lighter, easier, and more natural.

3

Small interactions can carry meaning

Inviting friends, coordinating plans, and showing up together may seem simple but during difficult times, those moments become deeply valuable.
