Mobile App Development at Cryptware
A good mobile app puts your service in your customer’s pocket, or gives your field team the tools they need wherever they are. We build high-performance native and cross-platform apps for iOS and Android — designed for engagement, built for reliability and optimised for growth.
We help you choose between native and cross-platform development based on your audience, budget and features, then take the app from first wireframe to store approval. Because we also build back ends and web platforms, your app, APIs and admin panel are designed to work together from the start.
Key features
We handle the whole journey — design, development, back end and release.
Native iOS & Android apps
Platform-specific apps built with Kotlin and native iOS tooling, where performance and device features matter most.
Cross-platform apps
One codebase for iOS and Android with Flutter, React Native or .NET MAUI, reducing cost and time to market.
Push notifications & engagement
Timely, relevant notifications and in-app messages that bring users back without overwhelming them.
Offline support & sync
Apps that keep working on patchy connections and sync data safely once the network returns.
APIs & back-end connectivity
Secure APIs, admin panels and cloud back ends that power your app and connect it to your existing systems.
App store deployment
We prepare builds and store listings and manage submission and review on the App Store and Google Play.
How we work
A clear, collaborative process with daily progress updates and a dedicated project manager from start to finish.
Discover
We clarify who will use the app, what they need to do and which devices and platforms matter most.
Plan
We map user journeys, choose native or cross-platform, and define the MVP feature set and release plan.
Build
Screens and features are built in sprints, with test builds shared on real devices throughout development.
Launch
We handle store submission, release configuration and analytics, so you can track adoption from day one.
Support
We keep the app compatible with new OS versions, fix issues quickly and ship improvements based on user feedback.

Why work with Cryptware
The right approach for your budget
An honest recommendation on native versus cross-platform, based on what your app really needs.
Designed for real users
Clear navigation, readable screens and quick load times help people adopt the app and keep using it.
App, API and admin together
We build the mobile app alongside its back end and admin tools, so every piece fits.
Try it on your phone early
Regular test builds let you use new features on your own device long before launch.
Frequently asked questions
Should I choose native or cross-platform development?
Cross-platform development with Flutter or React Native suits most business apps and lets you launch on iOS and Android from one codebase. Native development makes sense when you need maximum performance or deep device features. We’ll recommend the best fit once we understand your requirements.
Do you publish the app to the App Store and Google Play?
Yes. We prepare the builds and store listings and manage the submission process. The app is published under your own developer accounts.
Can the app work offline?
Yes, where the use case needs it. Data can be stored on the device and synced with the server whenever a connection is available.
Can you build an app for our existing website or system?
Yes. We can build APIs on top of your current web platform or ERP, so the app works with the same data and business rules.
What happens after the app goes live?
We offer ongoing maintenance to keep the app compatible with new iOS and Android releases, fix bugs and roll out new features.
