End-to-End Mobile App Capabilities
From consumer apps to enterprise mobility solutions — we design, build, and launch mobile experiences that perform on every device and delight every user.
Cross-Platform Apps
One codebase, two stores. We build Flutter and React Native apps that look and feel native on both Android and iOS — reducing cost without compromising quality.
Native Android Apps
When performance and platform depth matter most — Kotlin-native Android apps with full access to device hardware, background processing, and Material You design.
Native iOS Apps
Swift-native iOS apps that feel at home on iPhone and iPad — following Apple HIG, optimised for App Store review, and built with SwiftUI for modern, fluid interfaces.
Enterprise Mobility Apps
Field force apps, internal tools, inspection systems, and offline-capable enterprise apps that integrate with your ERP, CRM, or back-office — with SSO and MDM support.
App Backend & APIs
Scalable REST and GraphQL backends, real-time push notifications, secure authentication (OTP, biometric, OAuth), and cloud storage — purpose-built to power mobile apps.
App Maintenance & Upgrades
OS upgrades, new SDK migrations, performance tuning, crash analytics, and feature roadmap execution — we keep your existing app stable and store-compliant long term.
Choose the Right Platform Strategy
Not every app needs the same approach. We help you choose the right strategy based on your audience, budget, and performance requirements.
Cross-Platform
Recommended for mostOne codebase ships to both Android and iOS. ~80% lower development cost vs. two separate native apps. Best for business apps, marketplaces, and startups.
Native Android
Max platform depthPure Kotlin development for maximum performance, deep hardware access (NFC, Bluetooth, background services), and full Android ecosystem integration.
Native iOS
Apple-first experienceSwift and SwiftUI development targeting the Apple ecosystem — iPhone, iPad, Apple Watch, and Mac Catalyst. Built for App Store approval on the first submission.
Backend & Database
Cloud & Infra
Design & QA
From Idea to App Store in Weeks
A structured, milestone-driven process that keeps your app on track and in your hands as early as possible.
Discovery & Platform Choice
We map your user journeys, business goals, and technical requirements. We recommend the right platform strategy — cross-platform or native — with a clear rationale and scope.
UI/UX Design
User flows, wireframes, and high-fidelity Figma prototypes — designed to platform guidelines (Material You for Android, HIG for iOS). We design for thumbs, not cursors.
Agile Development
Two-week sprints with builds shared via TestFlight or Firebase App Distribution. You test real builds throughout — not just at the end. Bugs get caught early, not in production.
Device & Performance Testing
Tested across 15+ real devices covering fragmented Android versions and current iOS releases. We run performance profiling, memory analysis, and network condition testing.
Store Submission & Launch
We handle Play Store and App Store submission — screenshots, descriptions, metadata, privacy policy, and compliance checklist. We've navigated Apple review many times, so we know the pitfalls.
Post-Launch Monitoring
Crash analytics via Firebase Crashlytics, usage analytics, rating monitoring, and a post-launch support window. We stay on until your app is stable in the wild.
Why Clients Choose Rentree Labs for Mobile
We've Shipped Our Own Apps
Skool24 and Digital Code Camp are live, real-user products built in-house. We understand what it takes to navigate store reviews, handle real-world device bugs, and iterate based on user feedback — because we do it ourselves.
Performance Is Non-Negotiable
Slow apps get uninstalled. We profile memory usage, optimise render cycles, and test on low-end devices as standard — so your app performs on a ₹8,000 phone, not just a flagship.
You Own the Source Code
No lock-in. From day one, you own your app's source code, store accounts, and signing certificates. We document the architecture so any competent developer — yours or ours — can take it forward.
Design, Dev & Backend Under One Roof
UI/UX design, mobile development, backend APIs, and cloud infrastructure — all handled in-house in Delhi. No freelancer coordination, no timezone gaps, no "that's not our scope" conversations.
Industries We've Built Apps For
Mobile apps look different in every industry — an EdTech app needs offline sync; a field-ops app needs GPS and camera access. We understand the nuances.
