Two codebases, double the cost
Separate iOS and Android apps double the effort for every feature. Cross-platform frameworks let one team ship to both stores.

Web apps, mobile applications, SaaS platforms, customer portals, and internal applications.
What Our App Development Service Covers
Calycogenics builds mobile and web applications for customers, partners and internal teams. We use cross-platform frameworks such as React Native, Expo and Flutter so one codebase runs on iOS and Android, which cuts development and maintenance effort compared with two native apps.
For products that live mainly in the browser, we build progressive web apps and multi-tenant SaaS platforms with real-time sync, push notifications and offline support where it matters.
Fluid, cross-platform mobile and web applications with offline-first capabilities, real-time sync, and native device integration.
Who It Is For
- Businesses launching a customer-facing mobile app
- SaaS founders building a multi-tenant platform
- Operations teams that need a field or internal app
- Companies extending an existing web product to mobile
Key Deliverables
- iOS & Android Cross-Platform Mobile Apps
- Progressive Web Apps (PWA)
- Multi-Tenant SaaS Application Platforms
- Real-Time In-App Push Notifications
- App Store & Google Play Submission Support
Problems We Solve
Poor offline and network handling
Apps used in the field must cope with weak connectivity. We design sync and caching so the app stays usable offline.
Store submission delays
App Store and Google Play reviews can reject builds for policy issues. We prepare listings, privacy details and builds to reduce rejections.
How We Approach App Development
Mobile projects start with the few journeys users will repeat most often, such as logging in, completing a core task, and getting notified when something changes. We prototype these first, test them with real users, and only then build out the rest of the app.
We share a single API between the mobile app, web app, and admin tools, so business rules live in one place. Releases go through automated builds and internal test tracks before reaching the stores, and crash reporting and analytics are in place from day one so issues are found before users report them.
Technologies We Use
- React Native
- Flutter
- Expo
- Node.js
- Firebase
- Supabase
How We Deliver App Development
Every Calycogenics project follows the same accountable four-phase delivery cycle.
01
Clarity & Technical Scoping
We map your existing bottlenecks, user flows, and integrations. You receive a clear, unambiguous scope and milestone roadmap before a single line of code is written.
02
Architecture & System Design
We design high-converting interfaces and solid technical schemas, ensuring data models, APIs, and services are built for speed and security.
03
Full-Stack Engineering & QA
Senior builders write clean, tested code with automated CI/CD pipelines, rate-limiting, and rigorous cross-device verification.
04
Deployment, Monitoring & Care
We launch to production with zero downtime, configure analytics and telemetry, provide team training, and support ongoing iteration.
App Development FAQ
Native or cross-platform?
Most business apps are well served by React Native or Flutter. We recommend fully native development only when an app depends on platform-specific features or extreme performance.
Do you publish the app to the stores?
Yes. We handle build signing, store listings and submission for the App Store and Google Play under your developer accounts.
Can the app share a backend with our website?
Yes. We usually build a shared API so the website, mobile app and admin tools use the same data and business rules.
Do you support the app after launch?
Yes. We provide ongoing updates, OS compatibility fixes, monitoring and feature development.
How much does it cost to build an app?
It depends on the number of screens, user roles, integrations, and offline or real-time requirements. After a scoping session we provide a milestone-based quote.
Can you build an MVP first and add features later?
Yes. We recommend launching a focused MVP covering the core journey, gathering real user feedback, and then adding features in regular releases.
