Flutter app development cost in India is the number of hours each phase takes, added up, multiplied by the hourly rate in your quote. In the planning ranges below, a simple Flutter app takes about 118 to 192 hours, a mid-size app 420 to 700 hours, and a complex app 1,070 to 1,840 hours. At WebUncles, mobile apps (Android, iOS and Flutter) start from ₹1,00,000 in India and US$1,200 for overseas clients.
The hours are typical ranges for planning, not a WebUncles quote; your scope will move them. We show them so you can check the maths in any quote you receive. For Flutter work, see our hybrid app development service.
This post covers Flutter only. For app costs in general, including native apps, read our app development cost in India guide.
Why Flutter changes the maths
Flutter builds Android and iOS apps from one codebase. So the front-end phase is built once, not twice. Backend, design, testing and store release take about the same time whatever the framework. Flutter saves hours in one phase, not in all of them, and a quote that claims it halves the whole bill deserves a second look.
Flutter app development cost in India, phase by phase
Three example sizes. Simple: a login, a few screens and one list. Mid-size: accounts, payments or bookings, push notifications and an admin panel. Complex: real-time features, several user roles and many integrations.
| Phase | Simple app (hours) | Mid-size app (hours) | Complex app (hours) |
|---|---|---|---|
| Discovery and wireframes | 10 to 20 | 30 to 50 | 60 to 100 |
| UI design | 20 to 35 | 60 to 100 | 120 to 200 |
| Flutter front-end build | 40 to 60 | 150 to 250 | 400 to 700 |
| Backend and APIs | 25 to 40 | 120 to 200 | 350 to 600 |
| Testing and bug fixing | 15 to 25 | 50 to 80 | 120 to 200 |
| Store release and handover | 8 to 12 | 10 to 20 | 20 to 40 |
| Total | 118 to 192 | 420 to 700 | 1,070 to 1,840 |
Check the simple column: 10 + 20 + 40 + 25 + 15 + 8 = 118, and 20 + 35 + 60 + 40 + 25 + 12 = 192. Add up any quote’s phases the same way. If the parts do not sum to the total, ask why.
Turning hours into rupees
Cost = total hours × the hourly rate in your quote. Rates vary with the team, its location and the developer’s seniority, so we do not put a rate in this table. Use the one you are quoted.
The check also works backwards, and that is often more useful. Many quotes are a fixed price. Divide the price by the hours the developer says the job will take, and you get the rate you are really paying. Do it for two quotes on the same scope. If one works out far cheaper per hour, find out which phase it left out before you celebrate.
A worked example: a mid-size booking app
Take a booking app with customer accounts, a payment step, push notifications and a small admin panel. Using the middle of each mid-size range:
| Phase | Mid-point hours |
|---|---|
| Discovery and wireframes | 40 |
| UI design | 80 |
| Flutter front-end build | 200 |
| Backend and APIs | 160 |
| Testing and bug fixing | 65 |
| Store release and handover | 15 |
| Total | 560 |
Notice that the front-end phase is 200 of the 560 hours, about a third. That is the slice Flutter makes smaller. A missing phase, such as testing left out of a quote, moves the total more than a small difference in hourly rate does.
Have a feature list already? Get a quote and we will send hours by phase in the same format as this table, so you can compare it line by line.
Where extra hours hide
- Design revisions after the screens are signed off.
- Scope changes in the middle of the build.
- Slow approvals from your side.
- Store review: Apple and Google can reject a build and ask for changes.
- Data that has to be cleaned or imported before launch.
Agree a change process in writing: how a change is estimated and who approves it. That protects your budget more than a lower hourly rate does.
Fixed price or hourly billing
Fixed-price work suits a clear scope. You know the total before you start, and extra requests are quoted separately. Hourly or monthly billing suits an app whose features will change as you learn from users. Both can work. Ask which one the developer proposes and why.
Costs outside the development quote
- Apple Developer Program: US$99 per membership year, or in local currency where available (Apple, checked 14 Nov 2026).
- Google Play developer account: a US$25 one-time registration fee (Google Play Console Help, checked 14 Nov 2026).
- Servers or cloud hosting for the backend.
- Third-party services: SMS or OTP, email, maps and payment gateway fees.
- Updates after launch, because Android and iOS change every year.
What moves a Flutter quote up or down
- Number of screens and how custom the design is.
- User roles: one user type costs less than customer, vendor and admin.
- Real-time features such as chat or live location.
- Payments, wallets and subscriptions.
- Offline mode and data sync.
- Whether a backend already exists, or has to be built.
Checklist: does the Flutter quote add up?
- Hours are given per phase, not as one lump sum.
- The phase hours sum to the total.
- Design, backend, testing and store release all appear.
- The quote says who owns the source code and the store accounts.
- Revision rounds and the cost of a bug fix after launch are stated.
- You know who will actually write the code.
If you need only one platform, a native build can make sense. See our Android app development and iOS app development pages.

FAQ
How much does a Flutter app cost in India?
Total hours times the rate you are quoted. A simple app is roughly 118 to 192 hours in the ranges above. WebUncles mobile apps start from ₹1,00,000, and the final quote depends on scope.
Is Flutter cheaper than building native Android and iOS apps?
Usually for the front-end phase, because one codebase serves both platforms. Backend, design and testing hours stay about the same.
Do I pay Apple and Google separately?
Yes. Apple charges US$99 per membership year and Google Play a US$25 one-time fee (both checked 14 Nov 2026). They are not part of a build quote unless the quote says so.
How long does a Flutter app take?
Divide the total hours by the hours the team will work on your app each week. That gives a rough number of weeks. Ask the developer for a dated plan with demos along the way.
Can you build only the Flutter front end for my existing backend?
Mention it when you ask for a quote. If a backend already exists, the backend row in the table mostly drops out, and we would review your API documentation first.
Who owns the Flutter source code?
On our one-time custom projects, you do. Whoever builds your app, get code and store-account ownership written into the contract.
What does an app cost after launch?
Plan for hosting, third-party services and yearly updates. Ask your developer for a monthly maintenance figure before you sign.
