SPARKLE

A Social Chat App that Feels Like Yours

The Spark Behind Sparkle

Waiting shouldn’t feel like wasting time. This is exactly what the motto behind Sparkle was. A simple, local chat app that helps people connect with other people while killing time. This app's idea was initiated with keeping the users in mind who spend time waiting, very often. This includes waiting for a ride, sitting at a café, or hanging out at an event. Sparkle turns small moments into fun conversations.

Instead of scrolling endlessly, users can start public chats nearby, find a quick lunch buddy, or even start their own group.

The client came to us with one goal at that time: "We wanted to build something that connects people nearby with zero pressure." We took that seed and turned it into a mobile app, Sparkle. A lightweight social platform that brings strangers together through shared moments.

The Lobby:

use cases

This is where the connection starts. The Lobby is Sparkle’s first hello. Once users log in, they land on a live map of chats happening in the near radius. No digging, no refreshing. Just open the app, and the conversations come to you.

Each chat in the Lobby shows:

1 A name that sparks curiosity

2 The creator’s name and profile pic

3 A quick mood emoji

4 A topic cover to give context

5 The number of people and posts

6 A radius that shows who’s in range

New chats keep on popping live as they’re created, so no one misses a chance to jump in. And with endless scroll instead of clunky pagination. This provides a fast, smooth, and super user-friendly experience to the users.

Start a Chat, Instantly

use cases

Starting a conversation on Sparkle takes just a few seconds. No long forms. No fuss. Just tap, post, and you’re live.

Users can:

Add a photo, an upload from your mobile, or you can snap one instantly from the camera

Drop a mood emoji that shows people around you about your mood (or you may skip it too)

Write a quick topic where you ask a question, share a thought, or invite people over

Add a location (optional for those who want to stay anonymous)

Set the radius to keep control of how far the chat can reach

Smart Notifications

use cases

Nobody likes constant buzz. So, we made sure Sparkle only speaks when it matters.

Users get full control over what they want to hear and when. All missed or muted updates quietly land on the Notifications tab, easy to check, never in the way.

Clean, simple, and stress-free.

Wireframes

This is where we made sense with Sparkle's layout.

We kicked off with wireframes to map out Sparkle Chat’s main screens and user flows. The goal was very simple which was to keep the app easy to use and highlight what matters most: Posting and the Lobby.

Swipe gestures were added for quick actions like reporting or commenting. This was planned to cut down on spam and keep conversations clean. It was not just a UX thing, but also strategic. This also ticks off Apple’s guidelines for social apps by including clear block/report features.

Once the structure felt solid, we rolled into the design phase with a roadmap that worked.

Development

We followed the Scrum model with short, weekly sprints.

Before kicking off each sprint, the team huddled to clarify tasks, align timelines, and set clear expectations. No surprises, just smooth flow.

At the end of every sprint, our QA team ran tests to catch bugs early. Once cleared, we handed it to the client for a quick review before jumping to the next round.

Step by step, Sparkle Chat came to life, fast, sharp, and App Store-ready.

Color Scheme

The logo lit the spark — the UI kept it glowing.

We pulled warm tones from the logo and expanded them into a soft gradient built around oranges and yellows. The goal? A fire-inspired palette that feels bold, but easy on the eyes.

To balance the warmth, we kept the background white, clean, simple, and easy to read. For accents, we introduced a calm blue. It added contrast, guided user focus, and brought oxygen to our digital flame.

The result is a UI that feels light, warm, and inviting, just like a real conversation.
