We don't clone app templates. We don't drag-and-drop on FlutterFlow. Every line of code is written by Korteq engineers — from the first screen to the last API call. Custom-coded mobile applications built for performance, scale, and absolute ownership.
Template Apps Are Killing
Your Brand.
FlutterFlow charges monthly rent for infrastructure you'll never own. No-code apps hit performance walls at scale. You're shipping the same template as ten thousand other companies — and your users can tell.
The Template Trap
FlutterFlow and Adalo apps all look the same. Your company shouldn't share DNA with a weekend side-project built by someone watching a YouTube tutorial.
Platform Lock-in
No-code platforms own your app. They change pricing, break features, or shut down — and your entire business goes with it. You're building on rented land.
Performance Ceiling
Template apps hit walls at 10K users. Lag, crashes, and frozen screens destroy user trust. Custom architecture scales to millions — no bottlenecks, no platform limits.
Store Rejection Risk
Apple and Google reject apps that look templated, have poor performance, or lack native feel. Custom code passes every review — first time, every time.
Everything Engineered. Nothing Rented.
Every deliverable is hand-coded and purpose-built for your business. No templates. No no-code shortcuts.
Custom UI/UX Design
Figma-to-code precision. Brand-specific screens, interaction patterns, and mobile-first user flows — not a template's constraints.
Native & Cross-Platform Development
iOS and Android from a single codebase or fully native builds — React Native, Swift, or Kotlin. Optimized for each platform's guidelines and performance standards.
Push Notification Infrastructure
Firebase Cloud Messaging and Apple Push Notification service integration. Segmented, scheduled, and behavior-triggered notifications that drive engagement.
Admin Dashboard & CMS
Full-featured web-based admin panel for content management, user administration, push notification dispatch, and real-time analytics. Your backend, your control.
API & Backend Engineering
REST or GraphQL APIs, real-time WebSocket connections, database architecture, and server-side business logic. Engineered for speed and reliability.
Authentication & Security
Biometric login, OAuth 2.0, two-factor authentication, encrypted data storage, and certificate pinning. Enterprise-grade security from launch.
App Store Deployment
Full Apple App Store and Google Play Store submission. Asset preparation, metadata optimization, compliance review, and first-time approval handling.
Analytics & Crash Reporting
Firebase Analytics, Sentry crash reporting, and custom event tracking. Real-time visibility into user behavior, app health, and performance metrics.
AI-Powered Core (Add-on)
Embed our Autonomous Closer directly into your app. Offer 24/7 multilingual customer support, automated onboarding, and in-app upselling — powered by deep prompt engineering. Your app doesn't just function, it sells.
No FlutterFlow. No Adalo. Pure Engineering.
No drag-and-drop. No visual builders. Production-grade technologies trusted by the world's best engineering teams.
From Blueprint to App Store in 6 Milestones.
Structured milestone-based engagement. Full transparency at every phase.
App Architecture Audit (Week 1–2)
We analyze your business requirements, user flows, platform targets, and integration needs. The output: a detailed technical blueprint and project scope.
UI/UX Design & Prototyping (Week 3–4)
High-fidelity Figma prototypes for every screen — onboarding, core flows, settings, notifications. Interactive mockups approved before a single line of code is written.
Core Development Sprint (Week 5–10)
Frontend and backend engineering in parallel. Screen-by-screen build, API integration, state management, and data architecture. Weekly progress demos.
Integration & API Sprint (Week 11–12)
Push notifications, payment gateways, third-party APIs, analytics, and crash reporting. Every external connection battle-tested before shipping.
QA Testing & Security Audit (Week 13–14)
Device testing across iOS and Android, performance profiling, security penetration testing, and App Store guideline compliance. Nothing ships without passing every audit.
App Store Deployment & Handover (Week 15–16)
Apple App Store and Google Play submission, CI/CD pipeline setup, documentation, and complete code handover. The code is yours — forever.
Template Apps vs. Korteq Architecture
Template / No-Code Apps
- Generic UI shared by thousands of apps
- Platform-dependent — zero code ownership
- Performance limitations at scale
- Limited customization — fights the system
- Monthly platform fees and vendor lock-in
- Higher App Store rejection risk
Korteq Custom Architecture
- Unique app built exclusively for your brand
- 100% code ownership — yours forever
- Scales to millions of users seamlessly
- Unlimited customization — the system serves you
- Zero platform fees — you own the infrastructure
- Store-optimized for first-time approval
Transparent. Project-Based. No Surprises.
Enterprise-standard engagement model designed for trust and clarity.
Project-Based Pricing
Most enterprise mobile engagements start at $12,500 — scoped individually based on screen count, backend complexity, integrations, and platform targets. No hourly billing. No hidden fees. See full scope below.
50/50 Payment Structure
50% at project kickoff with signed contract. 50% upon App Store deployment. Industry-standard B2B payment model — no risk, no ambiguity, no surprises.
Annual Maintenance Contract
After the first year, an optional Annual Maintenance Contract covers hosting, security monitoring, OS compatibility updates, performance optimization, and priority support. Your application stays bulletproof.
Enterprise App Sprint
Custom-scoped to your business. Here's where most mobile engagements begin.
- ✓Custom UI/UX design & interactive prototyping
- ✓React Native dual-platform build (iOS & Android)
- ✓Scalable Node.js backend & API architecture

Completely different. This is custom-coded infrastructure built from scratch by our engineering team. No templates, no visual builders, no drag-and-drop limitations. You own 100% of the code, data, and infrastructure. No-code platforms rent you an app — we build you one that's yours forever, with native performance and zero platform dependencies.
Both. We recommend the best approach based on your requirements. React Native delivers near-native performance with a shared codebase for iOS and Android — ideal for most business applications. For apps that demand absolute platform-specific performance (gaming, AR, hardware-intensive), we build fully native with Swift (iOS) and Kotlin (Android). Your project lead will recommend the optimal approach during the Architecture Audit.
Typically 8 to 16 weeks depending on the number of screens, backend complexity, integrations, and platform targets. We provide a detailed timeline during the App Architecture Audit before any commitment. Weekly progress demos keep you informed at every milestone.
Absolutely. We offer AI-powered customer service and sales assistants as an add-on to any mobile app build. Our autonomous closer technology can handle inquiries, objections, and upselling — 24/7 in 50+ languages, directly inside your app. Ask your project lead about this during the Architecture Audit.
50% at project start with a signed contract, 50% upon App Store deployment. This is the standard enterprise B2B engagement model — clear, fair, and risk-free for both parties. No hourly billing, no scope creep.
The first year of hosting, security monitoring, OS compatibility updates, and critical patches is included in the project. After that, we offer an Annual Maintenance Contract (AMC) that covers hosting, security, performance optimization, and priority support — keeping your application bulletproof year after year.
Yes — 100%. Upon project completion, the entire codebase, design files, backend architecture, API documentation, and App Store credentials are handed over to you. No lock-in, no proprietary restrictions. It's your intellectual property.
Yes. We handle the complete submission process for both Apple App Store and Google Play — including asset preparation, metadata optimization, compliance review, and guideline adherence. Our custom-coded apps are built to pass review on the first attempt.
Your Users Deserve More Than a Template.
Stop renting. Stop compromising on performance. Let Korteq engineers build the mobile application your brand deserves — custom-coded, enterprise-grade, and yours forever.
