// Mobile Security by Design
Built for App Stores and Attackers Alike
Mobile apps face a different set of risks than web apps, from insecure local storage to weak API communication and reverse engineering. Our developers build with these risks in mind from day one, so your app passes app store review and holds up against real-world attack attempts.
Development follows the OWASP Mobile Application Security Verification Standard, with the personal data your app collects designed around UK GDPR from the first release onwards.
- Secure Local Storage and Encrypted Communication
- Protection against Reverse Engineering and Tampering
- Compliance with App Store Security Requirements
- Reduced Risk of Data Leaks and Account Takeover

React Native or Flutter where a shared codebase is the better fit.
Secure API Integration
Encrypted, authenticated communication between app and backend.
Biometric Authentication
Face ID, fingerprint and secure session handling implemented properly.
App Store Submission Support
Guidance through review so security requirements do not delay launch.
Post-Launch Updates
Ongoing patching and security updates after your app goes live.
// Methodology
How We Build Your Mobile App
- 01
Secure Architecture Planning
We plan data storage, transport and authentication before the build starts.
- 02
Development
Secure coding practices applied across both platforms consistently.
- 03
Encrypted Communication
API traffic between app and backend secured and certificate pinned.
- 04
Security Testing
Testing across the development lifecycle, not just before submission.
- 05
Release and Support
A final review before submission, then ongoing updates and patching.
// Ready when you are
Put your secure mobile app development services to the test.
// Impact
Why Mobile App Security Matters
Apps Store Data on the Device
Sensitive data held locally makes device compromise a real risk.
// Our Development Approach
- Secure architecture planning before build starts
- Encrypted API communication between app and backend
- Regular security testing across the development lifecycle

iOS, Android, React Native and Flutter builds, whatever fits your product.
OWASP MASVS Aligned
Development follows recognised mobile application security standards.
UK Data Handling
Built with UK GDPR and Data Protection Act expectations in mind.
Post-Launch Monitoring
Ongoing updates and patching after your app goes live.
We build for both platforms, either natively or through cross-platform frameworks like React Native and Flutter.
