Apps That
Work While
You Sleep.
Graphicosmos designs and develops high-performance mobile apps — iOS, Android, and cross-platform — built fast, scalable, and engineered to turn users into paying customers.
Not Just Functional.
Built to Retain.
Most apps look good on day one and get uninstalled by day seven. We build apps engineered around one goal — keeping users engaged and turning them into repeat, paying customers. Design and development in one team, one process, zero handoff friction.
From MVPs to full-scale platforms, we deliver on time, on brief, and on budget — every time.
See What We BuildWhat We Build
iOS Apps
Native and cross-platform apps built for the Apple ecosystem — polished UI, smooth performance, and full App Store compliance from submission to approval.
Android Apps
Fast, stable Android builds tuned for a wide range of devices — Material Design guidelines, Play Store optimisation, and battery-conscious performance.
Cross-Platform Apps
One codebase, two platforms — Flutter or React Native builds that ship faster and cost less without compromising on native-feel performance.
eCommerce & Marketplace Apps
Product listings, cart, checkout, payment gateways, and order tracking — built for high-volume transactions and a friction-free buying experience.
SaaS & Booking Platforms
Subscription apps, appointment and booking systems, dashboards, and admin panels — built to scale with your user base from day one.
App Redesigns & Migrations
Your current app is losing you users. We audit what's broken — UX, performance, retention — and rebuild it into an asset that keeps people coming back.
Our Design & Dev Process
Every deliverable, every phase — zero surprises.
We start with a deep-dive into your business, users, competitors, and goals. We map user flows, define retention metrics, and establish a clear feature list and platform strategy before a single screen is designed.
Low-fidelity wireframes first — screen flow and hierarchy — then high-fidelity Figma designs with your brand applied, following iOS Human Interface and Material Design guidelines. You approve every screen before development starts.
A stable app needs a stable backend. We build secure REST/GraphQL APIs, database architecture, authentication, and cloud infrastructure that scales as your user base grows.
We build on the right stack for your needs — native iOS/Android or cross-platform via Flutter or React Native. Clean, modular code and a maintainable architecture built for future feature additions.
A laggy app gets uninstalled. Every app we build is optimised for fast load times, smooth animations, low memory usage, and minimal battery drain across a wide range of devices.
Every app launches with retention infrastructure built in — push notifications, deep linking, onboarding flows, and analytics tracking so you know exactly how users behave from day one.
Multi-device testing, crash testing, and a pre-launch checklist of 40+ items. We handle App Store and Play Store submission, listing optimisation, and approval — so your app launches without rejection delays.
We don't disappear after launch. Monthly maintenance packages include OS-update compatibility, bug fixes, security monitoring, and performance reporting — so your app stays fast, stable, and current.

Why Graphicosmos for App?
Design + Dev in One Team
No handoff between a design agency and a dev shop. One team owns the whole project — faster delivery, better consistency, zero communication gaps.
Retention-First Thinking
Every screen decision is made with one question: does this keep the user coming back? Beauty without engagement is just decoration.
On-Time Delivery
We set clear milestones and hit them. If something changes, you hear from us first — not when a deadline is already missed.
You Own Everything
Full ownership of your source code, App Store/Play Store accounts, and backend from day one. No lock-in, no dependency on us for basic changes.
How We Work
A clear 6-step process from brief to launch — typically 6–10 weeks.
Brief & Discovery
Goals, users, competitors, and feature scope defined.
Wireframes
Screen flow and user journey mapped before visual design.
Design
Full Figma designs approved before development starts.
Development
Built clean, fast, and scalable on the right stack.
QA & Testing
40-point checklist across devices and OS versions.
Launch
Store submission, listing setup. Live and discoverable day one.

Frequently Asked Questions
How long does an app take to build?
A standard MVP takes 6–8 weeks. Full-featured apps with custom backend typically take 10–14 weeks depending on scope. Timeline depends on how quickly you provide content and feedback during the approval stages.
Should I build native or cross-platform?
Cross-platform (Flutter/React Native) is faster and cheaper for most apps and covers iOS + Android from one codebase. Native is worth it when you need heavy device-specific performance — AR, complex animations, or deep hardware integration. We'll recommend the right fit after understanding your requirements.
Do you handle App Store and Play Store submission?
Yes — we handle the entire submission process, including listing copy, screenshots, and compliance checks, under your own developer accounts. You own the accounts directly; we don't act as a middleman.
Do you redesign existing apps?
Yes — redesigns and migrations are common. We audit your current app for UX issues, performance problems, and retention gaps before we design anything, then migrate existing data and rebuild a version that performs significantly better.
Is a backend/API included in the build?
Yes, when your app needs one — user accounts, data storage, and business logic all require a backend. We build and host secure APIs and databases as part of the project, or integrate with your existing backend if you have one.
What information do you need to get started?
A brief call or a filled-out project brief form is enough to get started. We'll ask about your business, target users, competitors, core features, and any design references. From there we send a detailed proposal with scope, timeline, and pricing within 48 hours.
