Chat App Concept
Last Updated on July 3, 2026 by Editorial Team
UI kit for a chat app, created by Raka Caesar. The freebie contains 10 app screens: Chat Calls, 2 Detail (with and without keyboard), Edit, Chat, Contact, Settings, 3 Onboarding (for different types of contact).
Look closely at the screens fanned out behind the phone mockup and you can see how deliberately this chat app concept was built around a single accent color.
The deep purple header bars, message bubbles, and onboarding backgrounds carry the identity from screen to screen, while white space and light gray list rows keep the interface breathable and easy to scan.
It reads as a modern messaging app UI kit rather than a generic wireframe set, with rounded avatar photos, soft drop shadows on cards, and a friendly illustrated character on the welcome screen that gives the whole concept some personality instead of feeling clinical.
The onboarding screens do a lot of the storytelling here. “Fast Messaging” and “Free Call” slides pair short, benefit-driven copy with a simple illustration and a bold white call-to-action button, which is exactly the pattern used by real messaging apps to walk new users through core features before they land on the inbox.
That makes this concept genuinely useful as a reference for pitch decks, app store preview graphics, or the first few frames of a mobile app prototype where you need to sell the value of chat and calling features fast.
The chat list and contact screens, meanwhile, show how the same purple system holds up in denser, data-heavy layouts: timestamps, unread indicators, search bars, and rows of contacts with phone numbers all sit comfortably inside the same visual language.
Where This Chat UI Kit Comes In Handy
This is a solid starting point for anyone mocking up a messaging feature, whether that is a standalone chat app, a customer support widget, or an in-app messaging tab bolted onto a marketplace or social product.
It works well for:
- Mobile app UI/UX case studies and portfolio pieces that need believable chat and calling screens
- Early-stage app prototypes where founders need to visualize onboarding, contacts, and conversation flows
- Client presentations for messaging, dating, or social features where a polished purple theme photographs well in a mockup
- Design students studying how onboarding copy, iconography, and chat bubbles work together in a cohesive flow
Because the screens already cover onboarding, contacts, calls, and conversation detail with and without the keyboard open, you get a fairly complete map of the states a real chat app needs to design, which saves time compared to building that structure from a blank canvas.
If you want to adapt the concept to your own brand, the fastest change is swapping the purple for your primary color across headers, buttons, and message bubbles, since the layout is built to carry a single dominant hue rather than a busy palette.
From there, replace the placeholder avatars and names with your own contact photography or illustration style, and adjust the onboarding illustration and copy to describe your actual feature set instead of generic messaging claims.
Keep the sent and received bubbles visually distinct, as they already are here through color and alignment, since that contrast is what makes a chat screen readable at a glance.
When you drop these screens into a phone mockup for a presentation or store listing, pair them with a clean device frame and a simple gradient or solid background, similar to the teal-to-blue backdrop used in this preview, so the interface itself stays the center of attention.
