Mobile App Development .
iSkylar designs and builds mobile applications across iOS, Android, and cross-platform, from first-time founders shipping an MVP to established businesses launching their second app or replacing a legacy mobile product. We bring 12+ years of mobile delivery, a full in-house design team, and engineers who are hands-on with the platform SDKs, not just wrapping web views and calling it native.
What We Build
Native iOS Apps
Swift and SwiftUI applications built to Apple's Human Interface Guidelines — optimised for the latest iPhone and iPad hardware, compliant with App Store requirements, and designed to earn 4.5+ star ratings.
Native Android Apps
Kotlin and Jetpack Compose applications that perform across the full range of Android devices and OS versions — from flagship phones to mid-range hardware that your real users actually carry.
Cross-Platform Apps
Flutter and React Native applications that deliver native performance and platform-appropriate UI on both iOS and Android from a single codebase — cutting time to market without cutting quality.
Enterprise Mobile Solutions
Offline-first architecture, MDM compatibility, SSO and biometric authentication, role-based access, and push notification workflows — we build enterprise mobile tools that field teams use daily and IT departments trust.
UI/UX Design for Mobile
Platform-native design systems — Material Design 3 for Android, Apple HIG for iOS — combined with your brand identity. Every screen covers every state, every transition is prototyped, and accessibility is standard not optional.
App Store Launch & Optimisation
Full submission management for both stores — metadata, screenshots, App Preview videos, keyword strategy, content rating, privacy compliance, and review cycle management until both apps are live and ranking.
Delivered faster with AI tooling
We don't just write code; we orchestrate intelligence. By integrating Copilot-assisted generation and AI-driven automated testing, we reduce time-to-market by up to 40%.
LLM-backed development to eliminate boilerplate delays.
Anticipating edge cases before they enter production.
The iSkylar Tech Stack
Our Development Journey
A streamlined, transparent path from vision to launch.
Discovery & Platform Strategy
1–2 weeks
We define your target platforms, user journeys, feature set, and tech stack recommendation — and produce a delivery plan with fixed milestones before design or development begins.
UI/UX Design
2–3 weeks
High-fidelity Figma prototypes for every screen and state on each platform. You interact with a clickable prototype before a single line of code is written — and approve every screen before we build.
Development
4–14 weeks
Two-week sprints. From sprint two you have a working build on TestFlight (iOS) and Play Internal Testing (Android) — a real app on your real device, not a demo recording or a staging screenshot.
QA & Device Testing
1–2 weeks
Real-device testing across iOS and Android covering 95%+ of the active market — different screen sizes, OS versions, manufacturers, and network conditions including offline scenarios.
Store Submission
3–7 days
We handle both App Store and Google Play submissions in parallel — privacy manifests, App Privacy labels, content ratings, store listings, and all review feedback until both apps are approved and live.
Post-Launch & Iteration
Ongoing
Crash monitoring via Sentry and Firebase Crashlytics, OS version compatibility updates, performance profiling, and feature iteration. CI/CD with Fastlane means future releases take hours, not days.

Frequently Asked Questions
Should I build native iOS and Android apps, or go cross-platform?+
It depends on your product. Native (Swift for iOS, Kotlin for Android) gives you the deepest platform integration and best performance — ideal for apps using camera, sensors, or platform-specific SDKs. Cross-platform (Flutter or React Native) cuts build time and cost when you need both stores quickly and your product does not rely on deep native APIs. We advise on the right call during discovery.
How long does mobile app development take?+
An MVP is typically 8–12 weeks from kickoff to both stores live. A full-featured product is usually 14–20 weeks. Timeline depends on feature scope, design complexity, and backend requirements. We give you a fixed milestone plan after the scoping session — not a rolling estimate.
How much does mobile app development cost?+
MVPs start from $10,000. Full product builds from $25,000. Pricing is based on platform choice, feature depth, design scope, and backend complexity. You receive a fixed-scope quote before signing, so there are no surprises mid-project.
Can you build for both iOS and Android at the same time?+
Yes. We deliver both platforms simultaneously — either as separate native codebases or as a shared Flutter or React Native project. For most new products, we recommend Flutter for the combined build and advise native for products where platform depth genuinely matters.
What third-party integrations do you handle?+
We regularly integrate Stripe and Razorpay for payments, Firebase and AWS Amplify for backend services, Mixpanel and Amplitude for analytics, Intercom for support, push notification providers, social login, maps, and custom REST or GraphQL APIs. If it has an SDK or API, we connect it.
Do you handle App Store and Google Play submission?+
Yes — both, simultaneously where applicable. We manage the full submission process for each platform including privacy manifests, content ratings, store listings, screenshots, App Preview videos, and all review feedback until your app is approved and live.
Who owns the source code and assets?+
You own everything — Swift and Kotlin source files, Flutter Dart code, Figma designs, CI/CD configuration, and all documentation. Full IP transfer at project close, no retained rights.
What post-launch support do you offer?+
We offer maintenance retainers covering crash monitoring, OS version compatibility, performance profiling, and feature iteration. Critical issues are responded to within 24 hours for active retainer clients. We also set up Fastlane CI/CD so your team can ship future updates without depending on us for every release.
