We are a mobile app development company that delivers custom iOS, Android, and cross-platform apps for startups and enterprises worldwide. From discovery to post-launch support, we plan mobile products around user needs, security requirements, performance, maintainability, and the operating context of the application.
We deliver custom mobile app development services for iOS, Android, and cross-platform applications. Our team builds secure, scalable, and user-ready mobile products for startups and enterprises worldwide.
01Swift and SwiftUI for iPhone and iPad, built to Apple HIG standards with full App Store submission. From concept to live on the App Store.
02Kotlin and Jetpack Compose for phones, tablets, and foldables, optimised for Google Play policies and Material Design 3 guidelines.
03One codebase for iOS and Android. Flutter for custom UI; React Native for JS teams. Cuts cost 30 to 50% vs two native builds without sacrificing quality.
04Installable web apps with native-like UX and offline support. We also rebuild outdated apps after a thorough codebase audit and technical review.
Industry requirements are considered during discovery and architecture planning, including applicable compliance needs, user expectations, integrations, data flows, and sector-specific operating constraints.

A structured delivery process keeps scope, design, engineering, testing, and release decisions visible throughout the engagement, with review points and deliverables agreed in the project plan.
Project brief, feature list, wireframes, and cost estimate. We define what gets built before coding begins.
Figma prototype, design system, and screen-by-screen sign-off before development starts.
Our UX & UI Design ServicesWorking demos are scheduled on the agreed sprint cadence so progress can be reviewed throughout delivery rather than only at final handover.
Device matrix testing, security validation, QA report and UAT sign-off before App Store submission.
Our Testing ServicesLive on App Store and Google Play. We handle metadata, privacy labels, and staged rollouts.
OS updates, security patches, bug resolution, and feature development on retainer or per-project.

Maintenance & Support PlansHonest estimates based on real project data. Ranges reflect our blended global delivery model. US-only engineering typically runs 2 to 3x higher for the same scope.
From the first scoping call to post-launch support, we are accountable for the complete outcome. One team, full lifecycle, zero hand-offs.
Dedicated PMs, async updates, and sprint demos scheduled around North America, Europe, and APAC timezones.
Fixed-scope quotes with itemised estimates. Scope changes are flagged before they are built, no invoice surprises.
One team owns wireframe to post-launch maintenance. No hand-offs between separate agencies or teams.

Budget, performance, and roadmap determine the answer. Here is the full comparison to help you choose the right approach.
| Native iOS / Android | Flutter | React Native | |
|---|---|---|---|
| Performance | Highest — direct OS access | Near-native | Near-native |
| Code Reuse | 0% — two codebases | 90 to 95% | 70 to 90% |
| Dev Cost | Higher | Lower | Lower |
| Dev Speed | Slower | Faster | Faster |
| UI Quality | Pixel-perfect, platform-native | Excellent custom UI | Good, some native widgets |
| Best For | Performance-critical apps | MVPs and fast launch | JS teams and SaaS products |

Everything founders and product teams ask before starting a mobile app project with us.
Costs range from $10,000 for a simple single-platform app to $250,000+ for a complex enterprise application. Mid-complexity (two platforms, payments, custom backend) runs $30K to $100K over 4 to 7 months. Enterprise with AI or compliance requirements: $100K to $250K+ over 6 to 14 months.
Simple apps take 2 to 4 months. Mid-complexity on two platforms: 4 to 7 months. Enterprise apps: 6 to 14 months. Key factors are requirements clarity at kickoff, approval cycle speed, third-party dependencies, and App Store review time.
Flutter is our default for most new projects, offering near-native performance, excellent custom UI, and a Google-backed ecosystem. React Native suits teams with strong JavaScript or React experience or those extending a web product into mobile. Both cut cost 30 to 50% vs two native builds.
Native means separate Swift (iOS) and Kotlin (Android) codebases with highest performance, full platform API access, and higher cost. Cross-platform (Flutter or React Native) uses one shared codebase for both platforms, reducing cost and time by 30 to 50% with near-native performance for most use cases.
Six stages: Discovery/Scoping (1 to 2 weeks), UX/UI Design (2 to 4 weeks), Agile Development in 2-week sprints (8 to 20 weeks), QA/Testing (2 to 4 weeks), App Store submission (1 to 2 weeks), and ongoing Maintenance. Each stage ends with a client deliverable and sign-off.
Yes. We sign a mutual NDA before any scoping conversation, on request, at no charge. Your ideas, business logic, and requirements stay fully confidential throughout the engagement.
Yes. Included in our standard process: metadata, screenshots, privacy labels (Apple), Data Safety sections (Google Play), staged rollouts, and App Store review team responses if required.
Monthly retainer or per-project basis: OS updates, bug resolution with defined SLAs, security patches, performance monitoring, and optional iterative feature development. We recommend a minimum 3-month post-launch engagement.
