Mobile App Development
Excelsior Technologies builds mobile applications for product owners who prioritise stability over rapid feature cycles. We operate out of Ahmedabad and Ontario to design, develop and deploy software that addresses the constraints of device fragmentation and OS-level background restrictions. While many agencies focus on feature expansion, we focus on the technical reality of connection-drop recovery and store compliance. We do not promise infinite scalability or zero-maintenance codebases; we deliver functional applications that manage the trade-offs between cross-platform abstraction and native performance. Our team includes experienced developers who manage the full lifecycle from initial architecture to final store submission, ensuring your product remains maintainable through evolving platform requirements.

What mobile app development includes
Native Android and iOS
We develop applications using Kotlin and Swift to access full hardware capabilities. This approach ensures your product benefits from the latest platform-specific features while minimising abstraction layer overhead.
Cross-platform Flutter development
We build with Flutter when rapid UI iteration is required across platforms. We acknowledge that this requires careful management of platform-specific limitations and potential performance bottlenecks during complex rendering tasks.
Offline-first data synchronisation
We implement local-first architectures to ensure your application remains functional during network loss. Our logic handles queuing, conflict resolution and eventual consistency when the device reconnects to the server.
Background task management
We navigate strict OS-level battery and background execution limits to manage push notifications and data syncing. We design these processes to avoid system-level termination and ensure consistent app behaviour.
App store submission
We manage the technical requirements for App Store and Play Store compliance. We handle the remediation of rejection notices and configure update paths to maintain long-term store availability.
Hardware sensor integration
We integrate camera, GPS and biometric sensors directly into your mobile workflows. We address the specific permission models and hardware variations required to ensure reliable data capture across diverse devices.
How we run a mobile app development project
Technical feasibility audit
Before writing code, we assess your core features against current OS background execution limits. We identify potential bottlenecks early to prevent architectural debt and ensure the product remains viable.
CI/CD environment setup
We establish automated pipelines to handle build versioning and deployment. This reduces manual errors and ensures that every release candidate undergoes consistent testing before it hits the production environment.
Iterative development sprints
Our sprints focus on state management and connection-drop recovery. We validate every feature against real-world network conditions rather than idealistic development environments, ensuring the UI remains responsive during data tasks.
Fragmented device testing
We test your application in our device lab, covering varied screen sizes, hardware specifications and OS versions. This process identifies layout issues and hardware-specific bugs before your users encounter them.
Mobile App Development questions
How do you handle the trade-offs between Flutter's development speed and native performance limitations?
We use Flutter for UI-heavy applications where speed of iteration is the priority. However, we acknowledge that Flutter can struggle with low-level hardware access and intensive image processing. If your project requires deep integration with native platform APIs, we will recommend a native Kotlin or Swift approach to avoid these performance limitations.
What is your process for managing app store rejections related to privacy and permission policies?
Store rejections are often technical debt in disguise. We treat them as part of the development cycle by strictly documenting permission usage and data collection processes. When a rejection occurs, we review the policy violation, adjust the implementation to meet the platform guidelines and resubmit with corrected documentation to resolve the issue.
Who retains full ownership of the source code and signing certificates upon project completion?
You retain full legal ownership of the source code, assets and signing certificates. Upon project completion, we transfer all repository access and digital keys to your team. We do not hold your project hostage with proprietary platform locks or secret keys, ensuring you maintain complete control over your application's future updates.
How do you ensure the app remains functional when the device loses network connectivity?
We adopt an offline-first architecture. Instead of expecting constant server communication, we cache data locally and manage state transitions during network drops. The application stores user inputs locally and synchronises with the backend once a stable connection is restored, preventing data loss and maintaining a fluid experience even in poor network conditions.
What specific mobile architectures are you not suited to build?
We are not suited for projects requiring heavy augmented reality engines, complex 3D gaming physics or high-frequency low-latency trading applications. These require specialised low-level development that falls outside our standard mobile engineering focus. We prefer building functional business, commerce and management applications where stability and data integrity are the primary requirements.
What happens to the project if a critical bug is discovered after the final store deployment?
We assist in diagnosing the root cause of the bug and preparing a patch. If the issue is a result of our development work, we prioritise the fix. For bugs arising from OS updates or third-party API changes, we work with you to implement the necessary adjustments to restore functionality as quickly as possible.
