If you ask five agencies what an app costs, you may get five very different numbers. That is not always because someone is overcharging. It is usually because the scope was described differently. Rather than guess a price for your idea, this guide explains what drives cost and how to ask for a quote you can compare.
The factors that move the price
- Platforms. One platform costs less than two. Cross-platform tools such as Flutter or React Native can share most of the code between Android and iOS.
- Features. Login, profiles, search, payments, chat, maps, notifications, offline mode and admin dashboards each add work.
- Design. A clean standard interface costs less than custom animations and a fully bespoke design system.
- Back end. Most apps need servers, a database and an admin panel. The back end is often as big as the app itself.
- Integrations. Payment gateways, SMS and WhatsApp, maps, ERP, CRM, KYC and third-party APIs.
- Security and compliance. Handling payments, health, financial or children's data needs extra care, and India's data protection law adds duties.
- Scale. An app for hundreds of users and one for millions need different infrastructure.
- Team and location. Experience matters. A senior team may cost more per hour and finish faster with fewer defects.
- Testing. Real-device testing across Android versions takes time.
- Store launch and after-launch support. App Store and Google Play setup, fixes and updates.
Typical timelines
These vary widely, but custom apps commonly take around three to six months from planning to launch, depending on scope. A focused first version can be quicker.
Start with an MVP
A minimum viable product (MVP) includes only the features needed to test your idea with real users.
- List every feature you want.
- Mark each one must have, should have or later.
- Build the "must haves" first.
- Learn from users, then add the rest.
This reduces both cost and risk. Many successful apps launched with a fraction of their eventual features.
Consider a PWA first
A progressive web app can be cheaper and faster than native apps for many use cases. See our guide comparing PWAs with native apps.
Hidden costs to budget for
- Cloud hosting and monitoring
- App Store and Google Play fees
- Third-party services (maps, SMS, notifications, analytics)
- Ongoing maintenance and OS updates
- Marketing to get your first users
- Support
How to get comparable quotes
Give each agency the same brief, including:
- Target users and the problem you solve
- Platforms
- Must-have features
- Any apps you admire for reference
- Integrations and compliance needs
- Timeline and budget range
Ask for an itemised estimate with assumptions, milestones, what is excluded and what happens after launch.
Red flags
- A fixed price with no written scope
- No questions asked about your users
- No mention of testing or security
- Unclear ownership of code and accounts

Frequently asked questions
How long does it take to build a custom mobile app?+
Custom apps commonly take around three to six months from planning to launch, depending on features, platforms and integrations. A focused MVP can be faster.
Why do app quotes differ so much?+
Usually because the scope differs: platforms, features, design depth, back end, integrations and testing. Give every agency the same detailed brief to get comparable estimates.
What is an MVP and why does it help?+
A minimum viable product includes only the essential features needed to test your idea with real users. It lowers cost and risk, and shows what to build next.
