REVC
SCOPEAndroid / iOS / Cross-Platform
We can build any app you need—Android, iOS, or cross-platform, whatever it is. From custom consumer apps to complex enterprise systems, we can build anything from the ground up. Whether you need a native Android app in Kotlin and Jetpack Compose, a native iOS app in Swift, or a unified cross-platform build in React Native or Flutter, you get a production-ready application backed by robust APIs and full App Store and Google Play Store deployment.

What we deliver
NATIVE
Native Android & iOS ApplicationsHigh-performance native apps engineered in Kotlin with Jetpack Compose for Android and Swift for iOS, ensuring fluid 60fps/120fps animations, native hardware access, and optimal battery efficiency.
CROSS
Cross-Platform Apps (React Native & Flutter)Build once, launch everywhere. Unified codebases powered by React Native or Flutter that deliver near-native speed, shared business logic, and synchronized feature rollouts across iOS and Android simultaneously.
BACKEND
Custom APIs, Cloud & Real-Time DatabasesSecure Node.js, NestJS & Express RESTful API backends paired with PostgreSQL, Firebase, or MySQL for real-time synchronization, offline support, user authentication, and enterprise-grade reliability.
PUBLISH
Play Store & App Store DeploymentFull release management: asset preparation, signing keys & certificates, privacy compliance, store listing optimization, and steering through Google Play & Apple App Store review approvals.
§2
Who it's for
OPER
Field Operations & Attendance TeamsCompanies needing custom mobile tracking, technician dispatching, attendance logging, or physical asset verification apps.
D2C
Direct-to-Consumer BrandsBrands looking to launch dedicated mobile loyalty experiences and direct ordering channels with push notification marketing.
START
Early-Stage StartupsFounders ready to translate Figma prototypes into a production-grade, verifiable native app for real customer trials.
§3
How it works: Build sequence
01
Wireframe
Map screens, user journeys, and data models.
02
Architecture
Set up Kotlin MVVM architecture and API endpoints.
03
Build & QA
Write clean code and test on real physical devices.
04
Release
Manage Google Play submission and track production logs.
100% source code ownership — you receive complete repository ownership, build keys, and database credentials upon completion.

Universal multi-platform SaaS application built with Flutter to work across Android, iOS, Web, and Desktop. Powered by a NestJS and PostgreSQL backend with automated fee collection, instant WhatsApp parent alerts, smart attendance, and school lifecycle administration.
Cross-platform mobile and web application built with Kotlin, Node.js, and MySQL for workforce attendance tracking, shift scheduling, and staff management.
Yes, we can build anything you need. Whether your project requires a native Android app in Kotlin and Jetpack Compose, a native iOS app in Swift, or a unified cross-platform application in React Native or Flutter that runs smoothly on both operating systems from a single codebase, we build it end-to-end including backends and store submission.
A focused MVP with core screens and API integration typically takes 4 to 8 weeks. Larger platforms with payment processing, role-based dashboards, and multi-user offline synchronization require 8 to 12 weeks.
Yes. We guide you through creating your Google Play Console developer account, prepare signing keys, configure privacy disclosures, and upload the signed bundle for store review.
Yes. Every app we build includes the backend infrastructure needed to run it—whether that is a Node.js REST API on a VPS, Firebase authentication and cloud database, or a self-hosted MySQL instance.
Yes. Android releases regular OS updates and SDK target requirements. We provide maintenance arrangements to update dependencies, test new Android versions, and push feature enhancements.
