PRIMARY STUDIO OFFERING · FLUTTER & REACT NATIVE
Flutter App Development for Startups and Growing Businesses
From product strategy and interface design to single-codebase Flutter development, backend API integration, offline data sync, and App Store release, we build iOS and Android apps users love.
✓ Direct founder engineering✓ Bi-weekly working builds✓ 100% IP ownership
COMMON BOTTLENECK
Why most projects struggle
Many mobile app builds fail because they suffer from high cross-platform friction, poor 30fps scrolling performance, confusing UI design, or extended development delays that push store release dates back by months.
HOW KENINSULA DELIVERS
What we guarantee in your build
A fluid, 60fps cross-platform mobile application that launches seamlessly on both iOS and Android from one clean codebase, secures high store reviews, and scales effortlessly as daily active users expand.
CORE DELIVERABLES
Everything included in your build.
We deliver complete, production-ready software without hidden gaps or handoff friction.
✓Cross-platform iOS & Android mobile applications built with Flutter or React Native
✓Product strategy, core feature prioritization, and 6–12 week MVP roadmap planning
✓Native micro-interactions, custom animations, and 60fps fluid touch response
✓Offline-first SQLite local data caching and background auto-retry cloud sync
✓Authentication (Biometrics, OAuth2, Firebase Auth), payments (Stripe, Apple/Google Pay), push notifications & analytics
✓Complete handling of App Store Connect & Google Play Console submission and compliance
✓100% source code, Git repository, Figma design assets, and intellectual property ownership
✓Post-launch maintenance, crash monitoring, performance tuning, and OS version upgrades
ENGINEERING DEPTH
Specialized capabilities.
Product Strategy & MVP Scope Planning
Filter out non-essential feature bloat to build a lean, high-impact MVP capable of gathering rapid user validation within 6 to 12 weeks.
UI/UX Product Design & Figma Prototyping
Interactive clickable Figma prototypes, WCAG AA contrast compliance, and human-centered mobile interface flows created before writing code.
Backend API, Authentication & Payment Integration
Connect secure Node.js/PostgreSQL APIs or Firebase backends with biometric unlock, Stripe payment gateways, and real-time push notification triggers.
Offline-First Local Sync & Native Hardware APIs
Enable field and operational users to record work offline, leveraging background GPS telemetry, camera barcode scanning, and automatic cloud retry sync.
App Store & Play Store Deployment
End-to-end management of iOS App Store Connect, Google Play Console, privacy manifests, signing certificates, and app store review guidelines.

PROJECT FIT
Is this the right engagement for you?
→Startup founders launching their flagship MVP mobile app on iOS & Android
→Logistics, field operations, retail, and FMCG companies digitizing operational workflows
→Direct-to-consumer (D2C) and SaaS businesses seeking higher mobile user retention
→Agencies needing a senior, founder-led engineering partner to deliver client apps
DELIVERY METHODOLOGY
A clear 4-step path to launch.
Transparent milestones and working builds throughout the engagement.
01
Product Discovery & Blueprint
We map user personas, primary workflows, technical architecture, and store compliance rules into a clear MVP specification.
02
Figma UI/UX & Clickable Prototype
High-fidelity interactive designs let you touch, test, and validate the mobile experience before writing expensive code.
03
Iterative Bi-Weekly Sprint Engineering
Bi-weekly working builds delivered directly to TestFlight and Google Play Internal Testing for transparent review.
04
App Store Deployment & Handover
App store submission approval, production monitoring, full IP transfer, and ongoing maintenance support.
PROOF OF THINKING

LogiFlow Driver & Freight Dispatch
UK Logistics & Fleet Management Startup (Confidential)
A production cross-platform Flutter mobile driver app and backend dispatch gateway engineered to coordinate 200+ commercial freight drivers with real-time GPS route telemetry and offline digital manifest signing.
THE CHALLENGE
Commercial delivery operations relied on paper manifests and manual phone calls. Spotty cellular connectivity in rural transit zones caused missing delivery receipts, 25% delivery status delays, and high administrative overhead.
THE SOLUTION
Designed and engineered an offline-first Flutter mobile application for iOS and Android. Implemented local SQLite caching with auto-retry background synchronization, digital parcel barcode scanning, and instant customer signature capture.

Keninsula is intentionally founder-led. Unlike traditional agencies where projects are handed off to rotating junior developers and non-technical account managers, you collaborate directly with the core engineering and design lead.
We bring sharp product judgment, modern mobile and full-stack engineering standards (Flutter, Next.js, PostgreSQL), and rigorous delivery discipline to every build.
No sales layersTechnical discussions directly with Parth Prajapati.
Bi-weekly working demosReal TestFlight and staging builds you can touch and test.
100% IP & NDA OwnershipStrict confidentiality, complete Git repository transfer.
FREQUENTLY ASKED
Mobile Apps questions answered.
Have questions about scope, pricing or delivery? Let’s discuss your requirements directly.
Flutter enables us to compile native ARM machine code for both iOS and Android from a single Dart codebase. It delivers 60fps UI performance using the Impeller rendering engine while reducing development and QA costs by 40–50% compared to building separate native Swift and Kotlin applications.
A focused first-release mobile MVP typically takes 6 to 12 weeks. We prioritize core user value in Phase 1 so you can get live in the App Store and Google Play quickly to collect feedback.
Yes. We manage provisioning profiles, app icons, splash screens, store metadata, screenshots, privacy policies, compliance declarations, and any reviewer feedback until your application is live.
You own 100% of the source code, design assets, and intellectual property from day one. All Git repositories and cloud credentials belong directly to your company.
We offer structured maintenance plans covering iOS/Android OS updates, Flutter dependency upgrades, crash monitoring, database scaling, and continuous feature development.
