    UI/UX Design

    Engage your users with an intuitive and beautiful app interface. Our designers specialise in user experience (UX) and user interface (UI) design to craft pixel-perfect layouts and smooth user flows. We create interactive prototypes and gather feedback early, so the final design is both visually compelling and easy to use. Your app will reflect your brand identity and deliver a seamless experience that keeps users coming back.

    App Development & Testing

    This is where your app idea becomes reality. Our skilled app developers code your application using modern, high-performance technologies (i.e., Swift, Kotlin, Flutter, React Native, and more) whilst following best practices for security and scalability. We use an agile development approach with continuous testing and quality assurance. Every feature is rigorously tested on real devices to ensure the app runs smoothly on all target platforms. You can expect efficient project management, transparent progress updates, and on-time delivery.

    Customized Marketing Strategies for Your Unique Needs

    Launch & Post-Launch Support

    Bringing your app to market is just the beginning. We handle app store submissions (Apple App Store and Google Play), including preparing descriptions, screenshots, and ensuring compliance with guidelines. After launch, Kurve provides ongoing post-launch support and maintenance. We monitor performance, fix any issues promptly, and release updates to enhance features or compatibility. Furthermore, our team also helps you iterate based on user feedback and analytics insights. Beyond development, Kurve’s unique strength is in growth—we can assist with app marketing, App Store Optimisation (ASO), user acquisition, and other strategies to scale your user base. With our post-launch support, you get a true long-term partner dedicated to your app’s success.

    Modern Technologies & Platforms We Use

    We leverage the latest technologies to build high-quality, future-proof applications. Our development team is proficient in all major modern programming languages and frameworks for mobile app development

    Flutter
    Google’s cutting-edge UI toolkit for cross-platform development. Flutter allows us to build iOS and Android apps from a single codebase, which accelerates development and ensures consistent performance across devices.

    React & React Native
    Using Facebook’s popular JavaScript library and its mobile framework React Native, we create native mobile apps with a shared JavaScript codebase​. This means faster development and a unified experience on both Android and iOS platforms without compromising on quality or user experience.

    Swift
    Our iOS app developers use Swift—Apple’s powerful and intuitive programming language—to build secure, high-performance native apps for iPhone and iPad​. Swift enables fast development and smooth integration with the entire Apple ecosystem (i.e., iOS, macOS, watchOS, and tvOS).

    Kotlin
    For Android app development, we rely on Kotlin, which has become Google’s preferred language for modern Android apps. Kotlin’s concise, expressive syntax and full interoperability with Java allow us to create robust Android applications efficiently.

    No-Code & Low-Code Tools
    For early-stage apps and rapid prototyping, we support no-code tools like FlutterFlow, Wanilla, Bubble, and Adalo. These platforms allow visual app building with logic and database integration, enabling fast launches without full-code development. They're ideal for MVPs, internal tools, and early validation, with clear upgrade paths as your product grows.

    Mobile App Development Agency Frameworks

    In addition, our full-stack expertise means we can work with a variety of other technologies as needed—from Objective-C and Java (for legacy app support) to web frameworks and back-end systems (Node.js, .NET, Python, etc.) that power your app’s server side. We choose the right tech stack for each project to ensure your app is built on a solid foundation.

    Comprehensive Tech Stack & Integrations for Your App

    Building a successful app isn’t only about the code you see—it’s also about the services and integrations behind the scenes. At Kurve, we set up a comprehensive tech ecosystem to support and grow your mobile application.

    • Analytics & Data: We integrate analytics tools (such as Google Analytics for Firebase, Mixpanel, or Amplitude) to track user behavior and key performance metrics. You’ll gain real-time insights into how users interact with your app, enabling data-driven improvements. We also implement attribution platforms like Adjust or AppsFlyer to measure the effectiveness of your marketing campaigns and user acquisition channels.
    • User Engagement & Push Notifications: Keeping users engaged is crucial. We incorporate engagement tools such as OneSignal, Firebase Cloud Messaging, or Customer.io for push notifications, in-app messaging, and email/SMS outreach. This allows you to send targeted messages, run promotional campaigns, and nurture user relationships right within your app, all of which help increase user retention and activity.
    • Subscription Billing & In-App Purchases: If your app will generate revenue through subscriptions or purchases, we’ve got you covered. Our team implements secure subscription billing systems, including integration with Apple App Store and Google Play in-app purchase APIs for mobile subscriptions. For added flexibility, we can also integrate with third-party solutions like RevenueCat or Stripe to manage cross-platform subscriptions, one-time purchases, and recurring payments seamlessly. We ensure that transactions are smooth and that revenue reporting is accurate and reliable.

    Working with Kurve on TikTok influencer outreach has been great. We are targeting the “mumtok” sphere to introduce Beanstalk – our award winning Junior ISA app. Kurve’s outreach strategy, onboarding of talent and managing of paid media were all instrumental in helping make the channel successful for us.

    Frequently Asked Questions

    The timeline depends on the complexity and features of the app. A basic MVP can take 8–12 weeks, while more advanced apps may require 3–6 months or more. We offer clear timelines during the discovery phase and work in agile sprints to deliver quickly without compromising quality.

    An MMP (Mobile Measurement Partner) is a platform that helps you track and attribute where your app installs and conversions come from — such as Meta Ads, TikTok, Google Ads, or influencers. Tools like Adjust, AppsFlyer, and Branch are common MMPs used to unify performance tracking across channels.

    At Kurve, we set up and configure your full analytics and attribution stack, including tools like Firebase, Mixpanel, Amplitude, Adjust, and more. We ensure your data is accurate, accessible, and actionable — so you can make informed decisions from day one.
