01 What we build
Native where it matters. Shared where it pays.
We recommend the stack after we understand the product, not before.
Native Android
Kotlin and Jetpack Compose for apps that feel at home on every Android phone, including the budget devices most of India uses.
- Kotlin and Jetpack Compose
- Offline-first data and sync
- Play Store listing and release
Native iOS
Swift and SwiftUI for apps that follow Apple's conventions and pass App Store review the first time.
- Swift and SwiftUI
- Apple sign-in, payments and notifications
- App Store submission and updates
Cross-platform
Flutter or React Native when one codebase for both stores is the right trade, with native modules where performance needs them.
- Flutter or React Native
- One team, two stores
- Shared design system
02 Built in from the start
The parts users expect, done properly.
These are the places apps usually break. We plan and test them first.
- 01Offline support
Works on a patchy connection and syncs cleanly when it returns.
- 02Payments
UPI, cards and wallets, with retries, refunds and receipts tested end to end.
- 03Push notifications
Delivered, deep-linked and respectful of the user's settings.
- 04Sign-in
Phone OTP, Google and Apple sign-in, with every failure path handled.
- 05Multi-language
Indian languages from the first version, not as an afterthought.
- 06Analytics & crash reporting
You see what users do and what breaks, without collecting what you don't need.
- 07Backend & APIs
The services behind the app, built or integrated, and contract-tested.
- 08Store release
Listings, screenshots, review notes and the updates that follow.
03 Tested before it ships
Real devices. Bad networks. Interrupted sessions.
An app is tested the way it will be used, not the way it was demoed.
Device matrix
Current Android and iOS versions on real phones, from flagships to the budget devices your users actually own.
Slow and offline
Slow 3G, dropped connections and switching between Wi‑Fi and mobile data mid-task.
Calls and notifications
Incoming calls, low battery, background and foreground switches, and OS permission prompts.
TalkBack and VoiceOver
Screen readers, font scaling and contrast, so the app works for everyone who installs it.
04 How an app gets built
Discover
Who the app is for, what it must do on day one, and what can wait.
Design
Flows and screens, tested with real users before a line of code.
Build
Short sprints with a working build you can install at the end of each one.
Test
Manual and automated testing on real devices, every sprint and before release.
Release
Store submission, launch monitoring and the updates that follow.
