®Mobile apps built for India and the world.
Native iOS and Android, or cross-platform with one codebase — we design, build, ship, and maintain mobile apps for startups, enterprises, and everything in between. AI-augmented development, real performance.
When to hire us
- You're launching a consumer mobile product
- You need an enterprise app for your sales / field / ops team
- You want one codebase across iOS and Android
- You have a web product and want a polished mobile companion
- Your current app is slow, crashes, or hasn't shipped an update in a year
What goes into a mobile app?
Mobile app development is the process of building applications that run natively on iOS or Android devices — or on both via a shared cross-platform codebase. The choice between native (Swift for iOS, Kotlin for Android) and cross-platform (React Native or Flutter) is the first architectural decision in any mobile project, and it depends on what the app actually needs: native development delivers the highest performance and deepest access to device hardware and OS features, while cross-platform lets one team ship to both stores with a shared codebase, reducing time-to-market and ongoing maintenance cost. Nowgray builds both, and we'll give you an honest recommendation based on your requirements — not on what we happen to prefer.
The Indian mobile market has specific demands that differ from Western norms: variable network conditions, lower-end device performance, UPI and Razorpay as the payment layer, and WhatsApp as a primary communication channel for many user flows. We design for these realities — offline-first data sync, low-bandwidth media loading, and optimised performance on mid-range Android devices. App Store Optimisation (ASO) is also part of our process: the metadata, screenshots, and video previews that determine how your app appears in the App Store and Play Store directly affect install volume. We handle the submission process and have a high first-submission approval rate because we know the review guidelines.
Post-launch, mobile apps require a different maintenance posture than web apps — OS updates break APIs on a fixed annual schedule, new device screen sizes require layout updates, and App Store policy changes can affect in-app purchase flows. We offer monthly retainer support that covers OS compatibility updates, crash fixes, performance regression monitoring, and incremental feature development. The apps we build are instrumented with crash analytics (Sentry or Firebase Crashlytics) and A/B testing frameworks from day one, so you have data from the first install rather than guessing why users drop off.
The capabilities, spelled out.
Native iOS
Swift + SwiftUI. App Store-ready architecture, Apple Sign-In, push notifications, in-app purchases, App Store review pipeline.
Native Android
Kotlin + Jetpack Compose. Material 3 design, Google Play Billing, Firebase, ProGuard hardening, Play Store launch.
Cross-platform
React Native or Flutter — one codebase, both stores. Right when speed-to-market matters more than 100% native polish.
AI-augmented features
On-device + cloud AI features — voice input, smart suggestions, document scanning with OCR, real-time translation, AI assistants inside your app.
App store success
ASO copy, screenshots, video previews, App Store and Play Store submissions, review-response handling. We get apps approved.
Lifecycle & updates
CI/CD, crash analytics, A/B testing, over-the-air updates (Expo / CodePush). We don't disappear after launch.
Our default stack.
We'll pick the right tools for your project — but if you don't care, this is what we usually reach for.
Outcomes, not just hours.
- Production app on both stores in 8–14 weeks, depending on scope
- App Store and Play Store approval on first or second submission — we know the rules
- Crash-free sessions above 99.5% by default
- One codebase strategy when budget matters; native when polish matters
