App development in Mumbai, for iOS & Android.
We're a Mumbai-based app development company that takes your app from idea to the App Store and Google Play. Strategy, UI/UX design, development, testing and launch are handled by one team, and that team also knows how to talk about what you've built.
Mobile apps built end to end, not in pieces
Most app projects stall in the handoffs: a designer here, a freelance developer there, and nobody who owns the whole thing. We work the other way round. One team plans the app with you, designs every screen, writes the code, tests it on real devices and ships it to the App Store and Google Play.
That covers customer-facing apps for startups, booking and ordering apps for service businesses, and internal apps that let field teams, sales staff or partners get work done from their phones.
Aureus Words started as a content and communications agency, so your app also gets what many development shops skip: clear onboarding copy, a store listing that sells, and a launch announcement people actually read.
What our app development services include
Everything it takes to plan, build, launch and look after a mobile app.
App strategy & planning
We pin down who the app is for, the problem it solves and the features the first version really needs, so the budget goes where it counts.
UI/UX design & prototyping
Wireframes, user flows and clickable prototypes you can try before a line of code is written, designed around Apple's and Google's interface guidelines.
iOS app development
Apps for iPhone and iPad that feel at home on Apple devices and are prepared for App Store review.
Android app development
Apps built for the wide range of Android phones and screen sizes your customers actually carry.
Backend, APIs & integrations
The server side that powers your app: user accounts, databases, admin panels, notifications, payments, maps and links to the tools you already run.
Testing & quality assurance
Functional, usability and device testing before launch, so bugs are caught by us rather than by your users.
App Store & Google Play launch
Store listings, screenshots, descriptions and submission, plus help through the review process.
Maintenance & updates
Bug fixes, OS updates, performance tuning and new features after launch, so the app keeps working as phones and platforms change.
Native or cross-platform: which is right for your app?
It depends on what the app has to do. Native apps, built separately for iOS and Android, suit products that lean heavily on device hardware, complex animation or top-end performance. Cross-platform apps share one codebase across both platforms, which usually means a leaner build for most business apps. We recommend an approach after scoping, not before.
What we look at before recommending one
- Which platforms your customers use
- Device features the app needs, such as camera, GPS or Bluetooth
- Performance and animation requirements
- Budget, timeline and plans for future features

Frequently asked questions
How much does it cost to build an app in Mumbai?
App costs depend on the number of features, whether you need iOS, Android or both, the design work and the integrations involved. After a short discovery call we share an itemized quote, so you know exactly what's included before any work begins.
How long does app development take?
It depends on scope. A focused first version is quicker to deliver than a feature-heavy product, so we often suggest launching with the essentials and adding features in phases. You get a timeline with milestones before development starts.
Do you build apps for both iPhone and Android?
Yes. We design and develop apps for iPhone, iPad and Android, and can launch on the App Store and Google Play at the same time.
Can you publish my app on the App Store and Google Play?
Yes. We prepare the store listing, screenshots and descriptions, submit the app, and handle the back-and-forth if a reviewer asks for changes.
Do you maintain the app after launch?
Yes. We offer maintenance for the apps we build, covering bug fixes, updates for new iOS and Android versions, performance improvements and new features.
Can you improve or redesign an existing app?
Yes. We review your current app, suggest improvements to its design and performance, and rework parts of it, or rebuild it where that makes more sense.
Do you work with clients outside Mumbai?
Yes. We meet Mumbai clients in person and work with businesses across India through video calls, shared test builds and regular check-ins.
