Custom App Development

From concept to
App Store.

We build native and cross-platform mobile applications that users love. Scalable architecture, intuitive UX, and flawless performance on every device.

Build My App
Why App Projects Fail

Most Apps Are Built. Very Few Are Used.

The App Store is full of apps that were built by developers, not by product thinkers. Technically functional but UX-hostile, performant on the dev's phone but broken on the user's device, launched without a retention loop and abandoned 3 months later. Building a mobile app is not a technical problem — it's a product problem. The technical execution matters enormously, but only if the product decisions are right first.

Before

“We have an app idea but don't know where to start”

After EVOLVRX

Discovery sprint — user personas defined, core user journeys mapped, technical scope validated, and an MVP feature set defined before a single line of code is written.

Before

“Our existing app has poor performance and negative reviews”

After EVOLVRX

Performance audit and rebuild — bottlenecks identified, architecture refactored where needed, and UX friction points addressed in a phased improvement roadmap.

Before

“Our development agency disappeared mid-project”

After EVOLVRX

Code audit and handoff management — we review what was built, document it properly, and take over development or rebuild from a clean foundation depending on what the audit finds.

Before

“We need an app that works on both iOS and Android”

After EVOLVRX

React Native cross-platform development — one codebase, native performance on both platforms, and a single team managing the release cycle for both App Store and Play Store.

The Full Picture

Everything Between "We Have an App Idea" and "We Have an App Users Love."

Not just development — a complete product engineering system.

Product Discovery & Scoping

User research, feature prioritization, MVP definition, and technical architecture designed before any code is written. The discovery sprint is the investment that prevents the most expensive mistakes in app development.

01

Product Discovery & Scoping

UI/UX Design

Mobile-first UX design — user flows, wireframes, and high-fidelity Figma prototypes built around your users' mental models. Designs tested with real users before handoff to development. Every interaction intentional.

02

UI/UX Design

React Native Development

Cross-platform native performance with a single codebase. React Native with Expo or bare workflow depending on requirements — allowing simultaneous iOS and Android releases with 80% code sharing. The industry standard for most consumer apps.

03

React Native Development

Native iOS (Swift)

Swift/SwiftUI for applications that require platform-specific capabilities, deep iOS integration, or maximum performance. Used when the use case demands full native access to hardware APIs, system frameworks, or Apple-platform exclusivity.

04

Native iOS (Swift)

Native Android (Kotlin)

Kotlin/Jetpack Compose for Android-first or Android-exclusive applications. Deep integration with Android system APIs, background services, hardware sensors, and Google platform services.

05

Native Android (Kotlin)

Backend & API Development

The mobile app is only as good as the backend powering it. We build the REST or GraphQL APIs, database architecture, and cloud infrastructure that the app depends on — scalable from Day 1 to hundreds of thousands of users.

06

Backend & API Development

App Store Optimization & Launch

Screenshots, preview videos, keyword-optimized descriptions, and ASO strategy for both App Store and Play Store. A well-optimized store listing dramatically affects organic download velocity on launch day.

07

App Store Optimization & Launch

Post-Launch Support & Iteration

Crash monitoring, user feedback analysis, and iterative releases. Apps require ongoing investment after launch — bug fixes, OS update compatibility, and feature development based on real usage data.

08

Post-Launch Support & Iteration

How It Works

From Napkin Idea to an App Users Download and Keep.

A five-step system built to take your app from idea to live product — with you seeing working software at every stage.

01 / 05
Discovery Sprint
01

Discovery Sprint

User personas, core journeys, competitive analysis, and MVP feature scope defined in a structured 2-week discovery. You end with a product brief, technical architecture document, and Figma wireframes — the foundation everything else builds on.

Design & Prototype
02

Design & Prototype

High-fidelity UI design in Figma, interactive prototype built, user testing conducted. Design reviewed by engineering before sign-off to ensure every interaction is technically feasible at the cost point in scope.

Development Sprints
03

Development Sprints

2-week agile sprints with weekly client demos. Core infrastructure built first, then feature-by-feature development. You see working software every two weeks — not a big reveal at the end.

QA & Testing
04

QA & Testing

Device testing matrix across iOS and Android, performance profiling, crash testing, and user acceptance testing. Nothing goes to the App Store until it passes our QA checklist on a minimum of 10 device/OS combinations.

Launch & Optimize
05

Launch & Optimize

App Store and Play Store submission managed by us. ASO applied on day one. Post-launch: crash monitoring, user feedback collection, and a 30-day bug fix window before transitioning to the ongoing iteration retainer.

What You Get

What Happens When the App Is Built Right From the Start.

Five outcomes that define what a well-built app delivers — and what a poorly built one never can.

Outcome 01

An App Your Users Actually Keep on Their Phone

Day 7 retention is the metric that separates successful apps from expensive ones. We build around the retention loops — habit formation, push notification strategy, and core value delivery in the first session. Apps that get used don't get deleted.

Outcome 02

Cross-Platform Without Compromise

React Native closes the gap with native performance while providing the economic efficiency of a single codebase. One team, one release cycle, two platform listings. For most use cases, users cannot tell the difference.

Outcome 03

A Product That Scales With Your Business

Architecture decisions made in sprint 1 determine whether the app handles 100 users or 100,000. We make the right decisions early — microservices where needed, proper database indexing, CDN for assets, and infrastructure that scales on demand.

Outcome 04

Full Codebase Ownership

You own the code, the repositories, and the App Store accounts. No vendor lock-in. We deliver clean, documented code that any competent developer can continue working on — including your in-house team if you build one.

Outcome 05

Visibility at Every Stage

You see working software every two weeks. Jira board visible, Git repository accessible, and weekly async video updates on what was shipped. No black boxes. No surprises at launch. No "it's almost done" for six months.

FAQ FAQ

Your app development questions, straight answers.

1

MVP with 5-8 core features: 10-16 weeks from discovery to App Store. More complex applications with custom backends, third-party integrations, and extensive feature sets: 20-30 weeks. We scope timeline precisely in the discovery sprint.

2

MVP apps: ₹15-40L depending on complexity. Full-featured consumer apps: ₹40-100L+. We provide a detailed scope breakdown with line-item estimates after the discovery sprint — no surprises mid-project.

3

For most consumer apps: React Native (cross-platform). For apps requiring deep platform integration, gaming, or maximum performance: native. For MVP validation: always cross-platform for cost efficiency. We advise based on your specific requirements.

4

Yes. A mobile app without a scalable backend is incomplete. We design and build the API, database, authentication, and cloud infrastructure that powers the app. The stack is designed to scale with your user base.

5

You do. 100% of the code, repositories, and intellectual property transfers to you at project completion. We don't retain licensing rights. You can take the code to any developer.

6

Yes. We perform a code audit first — architecture quality, security issues, scalability bottlenecks, and test coverage. The audit determines whether to refactor or rebuild. We don't recommend a rebuild unless the audit makes it clearly necessary.

7

Yes. We manage the full Apple App Store and Google Play Store submission process — screenshots, descriptions, compliance review, and any back-and-forth with the review team.

8

We handle the response and resubmission. App Store review issues are common, especially on first submission. We've navigated rejection responses before and know how to address review team feedback effectively.

9

Yes. AI integrations — GPT-4 for chat interfaces, image recognition, recommendation engines, and on-device ML with Core ML or TensorFlow Lite. AI features scoped and estimated in the discovery sprint.
