How much does mobile app development cost in India?
An app’s cost follows its features, platforms and integrations far more than its size. Here is what moves the price, a realistic timeline, and how to start without a large commitment. We use Stack18’s own phased approach as the worked example.

How much does it cost to build a mobile app in India?
App cost depends on features, platforms, integrations, offline needs and design depth, so a fair price needs a scope. Stack18 starts with a fixed-price App Discovery of 2 weeks, then an App Build of 8 to 14 weeks at a fixed price, using one codebase for Android and iOS. Ongoing releases run as a monthly team.
Seven features and choices that change the estimate.
Use this list to compare quotes and decide what belongs in version one.
| Driver | Why it changes the cost | Way to control it |
|---|---|---|
| Number of screens and flows | Each journey needs design, build and testing. | Ship the core journey first. |
| Platforms | Android only, iOS only, or both from one codebase. | One cross-platform codebase covers both stores. |
| Offline mode | Field and low-network use needs data sync and conflict handling. | Make only the essential flows work offline. |
| Payments and login | UPI, saved payments and OTP login add integration work. | Use standard providers rather than custom flows. |
| Backend and admin | The APIs, database and admin panel behind the app. | Reuse existing systems where you can. |
| Integrations | ERP, CRM, WhatsApp and push notifications. | List must-have integrations before scoping. |
| Design depth | A tested prototype costs more than a simple template, and saves rework. | Test the prototype before building it. |
How a typical engagement runs, week by week.
Senior people lead each phase and nothing ships without your approval.
Weeks 1–2: Discover
Users, journeys, devices and success metrics, ending in scope and flows.
Weeks 2–4: Design
App UX, a prototype and usability testing.
Weeks 4–11: Build
Sprints with test builds on your phone every week.
Weeks 11–12: Launch
Store submission, beta and phased rollout to both stores.
Weeks 12–16: Grow
Crash monitoring, analytics and feature updates.
Start small, then scale when it works.
Every engagement begins with a short fixed-price step so you can judge the fit.
App Discovery
- Best when
- You have an idea that needs flows, a prototype and a firm estimate.
- Duration
- 2 weeks, fixed price.
- You get
- User journeys, a tested prototype and a fixed-price quote.
App Build
- Best when
- You have a defined launch and want it in the stores.
- Duration
- 8 to 14 weeks, fixed price.
- You get
- Android and iOS apps, an admin panel, APIs and store launch.
App Growth Pod
- Best when
- Your app has an active roadmap.
- Duration
- Ongoing, monthly team.
- You get
- Regular releases, monitoring and improvement.
Plan for the costs that follow the store release.
Store accounts, hosting, push and messaging usage, crash monitoring and updates all continue after go-live. Ask every vendor what is included, and who owns the code and the store listing.
Five things to write down before you ask for a quote.
A clear brief gets comparable, accurate quotes.
Who is it for
Customers, field staff or partners, and what they must do.
Must-have features
The smallest set that makes version one worthwhile.
Devices and networks
Which phones, and whether users work offline.
Systems to connect
ERP, CRM, payments and messaging.
Success measure
The number that tells you the app is working.
Common questions.
How much does it cost to build a mobile app in India?
It depends on features, platforms, integrations, offline needs and design depth. Stack18 starts with a fixed-price App Discovery of 2 weeks, then a fixed-price App Build of 8 to 14 weeks.
How long does mobile app development take?
A typical Stack18 App Build takes 8 to 14 weeks to store launch, after a 2 week fixed-price discovery. Growth work then continues as a monthly team.
Do I need separate Android and iOS apps?
Not necessarily. Stack18 builds Android and iOS apps from one codebase, which reduces cost and keeps both in step.
Can the app work offline?
Yes. Stack18 designs apps for Indian networks and devices, with offline mode for field and low-network use.
What happens after the app is live?
Stack18 monitors crashes and usage and ships updates, either as a one-off or through a monthly App Growth Pod.
Can I start with a prototype first?
Yes. App Discovery is a 2 week fixed-price step that produces user journeys, a tested prototype and a fixed-price quote.
