Scope and prototype before code
We map the one job your users must complete, then the screens, data and device features that support it. An interactive Figma prototype lets you test the flow with real people in Delhi before development begins.

Mobile app development in Delhi, from idea to the App Store.
Zolarys designs and builds mobile apps for iOS and Android from our studio in Okhla, New Delhi. Founders and businesses across Delhi NCR come to us with an idea, a sketch or an existing app that needs rebuilding; we help shape the first release, design the screens, build the app and its backend, and prepare the App Store and Google Play submissions. Cross-platform builds in Flutter or React Native cover most products from one codebase; native Swift and Kotlin are used where the product needs them.
Is this the right fit?
A good fit for startups in Delhi NCR launching a consumer or B2B app, businesses giving customers or field staff a mobile tool, and anyone who already has an app that is slow, unstable or impossible to extend.
What we can deliver
The app, its backend and admin tools
An app is more than screens. We plan authentication, APIs, data storage, payments (including UPI and Indian payment gateways where needed), notifications and the admin panel your team uses to run it.
Testing on the phones your users own
We test on a spread of Android devices and iPhones, including low-end Android phones on patchy connections, denied permissions and failed requests — the conditions real users in India hit every day.
Store submission and launch support
Builds, listings, screenshots and privacy declarations are prepared for both stores. After launch we fix issues from the first wave of users and can continue as a retainer for new features.

Thaxas
Thaxas is Zolarys' flagship in-house AI education platform built to help students study smarter from their own course material instead of generic internet knowledge. Students can upload lecture slides, PDFs, notes and recordings into dedicated workspaces where AI instantly generates flashcards, quizzes, study guides, summaries, lecture notes and grounded answers with citations from their own content. Unlike traditional AI assistants, every response is tied directly to the student's uploaded material, creating a trustworthy study companion for exams, assignments and long-term retention.
Read the project storyDecisions to make before the build
Flutter, React Native or native?
One shared codebase in Flutter or React Native is the right call for most products and keeps two platforms in step for less cost. Native makes sense when the app leans hard on platform hardware, background work or raw performance. We recommend based on your feature list, not a house preference.
What should the first release include?
The first version should prove that a specific user will complete a specific task. We help you separate what the launch needs from what can wait for real usage data, which is usually where the budget is saved.
How the project moves forward
- 01Discovery in Okhla or on a call: users, the core task, platforms and budget.
- 02Prototype the journeys and agree on the backend and admin scope.
- 03Build in reviewable milestones with test builds on your own phone.
- 04Submit to the stores, launch and support the first release.
Budget and scope
Mobile apps are quoted per project. The number of workflows, integrations, device features and backend requirements drives the estimate more than the screen count, and cross-platform versus native changes it too. Share a brief or prototype and we will come back with a scoped estimate and milestone plan.
View website packages and estimatorQuestions about app development in delhi
Do you build apps for both Android and iPhone?
Yes. Most of our apps are built once in Flutter or React Native and released on both Google Play and the App Store. Where a product needs native Swift or Kotlin, we build natively.
How much does app development cost in Delhi?
There is no fixed menu price for an app because the scope varies so much. A focused first release with a handful of workflows costs far less than a marketplace with payments, chat and an admin platform. We quote after a scoping call, in writing, with milestones.
Can you take over an app built by another developer?
Yes, after a code review. We assess the codebase, backend and store accounts before recommending whether to extend, refactor or rebuild, and we tell you honestly which it is.
Do you handle App Store and Play Store submission?
Yes. We prepare builds, listings and privacy declarations and submit on your developer accounts. Review decisions remain with Apple and Google, and we handle any rework they ask for.
