Custom Mobile App Development Company | iOS & Android App Developers
CrayonBytes builds custom iOS & Android apps—native (Swift/Kotlin) and cross-platform (Flutter/React Native). UI/UX, backend, QA, launch, and maintenance—built for speed, scale, and retention.
Put Your Business in Their Pocket.
We design and develop intuitive, secure, and high-performance mobile apps that users love. From native iOS & Android to Flutter/React Native, CrayonBytes turns ideas into reliable mobile products—built for growth, retention, and real-world usage.
Mobile-First Solutions for a Mobile-First World
The average person spends hours a day on their phone—shopping, booking, learning, messaging, and managing life. CrayonBytes helps you capture that attention with mobile apps built for speed, simplicity, and long-term scalability.
Whether you need a customer-facing B2C app, an internal B2B tool, or an MVP to validate your idea, we handle the complete lifecycle:
- Discovery & product strategy
- Wireframes & UI/UX design
- Development (native or cross-platform)
- QA testing & performance optimization
- App Store / Play Store launch & post-launch support
Outcome: an app that looks premium, works smoothly, and supports your business goals—not just “an app that runs.”
Built for Performance, Built for Adoption
Native Performance
For best-in-class speed and smooth animations, we build native apps using:
- Swift / SwiftUI (iOS)
- Kotlin (Android)
Native development is ideal when you need advanced device features, maximum performance, or platform-specific UI excellence.
Cross-Platform Efficiency (Flutter / React Native)
Want to reduce cost and ship faster? We build cross-platform apps with a shared codebase—without compromising quality. Best for MVPs, startups, and businesses that want fast time-to-market across iOS and Android.
User Retention by Design
An app succeeds when users return. We build with retention in mind:
- push notifications (smart + non-spammy)
- onboarding flows that reduce drop-offs
- gamification and progress loops (where relevant)
- personalization and in-app messaging
Human-Centered Design. Production-Ready Engineering.
UI/UX Excellence (Not Just Code)
We don’t start with development—we start with usability. Our UI/UX approach focuses on:
- clear navigation and accessibility
- modern visuals consistent with your brand
- frictionless conversion paths (buy, book, sign up, contact)
Scalable Backend + Secure Architecture
Mobile apps need reliable infrastructure. We build secure, scalable systems including:
- robust APIs
- authentication and role-based access
- databases and admin panels
- cloud deployment and monitoring
Built to handle 10 users—or 10 million.
A Mobile App Team That Ships, Scales, and Supports
App Store & Play Store Approval
Apple and Google have strict policies and review processes. We prepare your app for submission, including:
- metadata and screenshots
- privacy requirements and permissions
- crash-free builds and compliance checks
So you launch smoothly—with fewer delays and rejections.

- Simple apps can start around $2k
- Complex, “Uber-like” apps require more time and budget
We provide a fixed quote after scoping features, screens, and integrations.
- Native is best for top-tier performance and deep device integrations.
- Hybrid/Cross-platform is faster to build and more cost-effective.
We’ll recommend the best approach based on your timeline, budget, and product goals.
Typical ranges:
- MVP: 3–6 weeks
- Medium complexity: 6–12 weeks
