Pick the model that fits your scope, budget, and risk tolerance. We can blend models across phases of the same engagement.
Fixed Price
Defined MVP
Clear scope, fixed budget, fixed timeline. Best for MVPs and well defined apps where the spec is locked at kickoff.
Time and Materials
Evolving scope
Pay for actual development hours. Best when requirements evolve and you want flexibility to iterate without renegotiating.
Dedicated Mobile Team
Sustained delivery
A named senior mobile team allocated full time. Acts as an extension of your development team, integrated into your sprints.
Maintenance Retainer
Post launch
Monthly retainer for OS upgrades, security patches, feature roadmap, and App Store and Play Store release management.

Cost Factors
What Actually Drives Mobile App Cost
Honest factors that move the estimate up or down. We share a detailed estimate after discovery.
App Complexity and Features
High impact
Number of screens, user flows, and platform features drives the largest cost component.
Platform Coverage
High impact
iOS only is cheaper. iOS plus Android cross platform is mid. Native iOS plus native Android costs the most.
Backend and Integrations
Medium impact
Each external API, payment processor, or third party service adds integration, testing, and monitoring cost.
Design Depth
Medium impact
Custom illustrations, animations, and design system maturity influence the design timeline.
Compliance and Security
Medium impact
HIPAA, PCI DSS, or financial compliance adds audit, documentation, and process overhead.
Timeline Compression
Variable impact
Tighter deadlines may require parallel teams or extended hours to maintain quality.
FAQ
Mobile App Buyer Questions, Answered
Direct answers about cost, timeline, platforms, IP, security, and post launch support.
How long does mobile app development take?
Simple MVP apps with basic features take 8 to 12 weeks. Mid complexity apps with 15 to 30 screens, integrations, and backend take 4 to 6 months. Enterprise apps with advanced features, custom backend, and multi platform launch can extend to 9 months or more. We share a detailed timeline after the discovery phase.
How much does mobile app development cost?
Mobile app development cost typically ranges from 25,000 USD for an MVP to 250,000 USD or more for enterprise apps. Cost depends on platform coverage, feature complexity, integration count, design depth, and compliance requirements. We share a detailed estimate after discovery.
What is the difference between native and cross platform development?
Native development means writing separate apps in Swift for iOS and Kotlin for Android. Performance is best but cost is highest. Cross platform with Flutter or React Native uses one codebase for both platforms, reducing cost and time to market with near native performance. We help you choose based on app complexity, budget, and long term maintenance plan.
Should I build a native app or a cross platform app?
Native is best for apps that need maximum performance, deep platform integration, or platform specific features like ARKit, HealthKit, or Wear OS. Cross platform is best for products that need to launch on iOS and Android simultaneously, have limited budget, or expect frequent feature iteration. Our architects evaluate which fits your roadmap during discovery.
Which technology is best for mobile app development?
For iOS, Swift with SwiftUI is the modern default. For Android, Kotlin with Jetpack Compose. For cross platform, Flutter has the best UI performance and is gaining enterprise adoption. React Native is preferred if your team already runs React on the web. We pick based on your team, performance needs, and long term roadmap.
Do you handle App Store and Google Play submission?
Yes. We manage the entire submission process including app signing, screenshot generation, App Store Optimization, privacy disclosures, review responses, and re submission for rejections. Your app reaches the store ready.
Can you migrate or modernize an existing mobile app?
Yes. We handle legacy framework migrations including Objective-C to Swift, Java to Kotlin, Cordova to Flutter or React Native. We also do performance audits, OS version upgrades, and full rewrites when the codebase has run its course.
Do you provide post launch maintenance and support?
Yes. We offer monthly maintenance retainers covering OS upgrades, security patches, third party SDK updates, crash monitoring, performance optimization, and feature roadmap iterations. The team that built your app stays on to maintain it.
What about App Store Optimization and marketing?
We deliver App Store Optimization including keyword research, listing copy, screenshot design, A/B testing for store conversion, and review management. For broader marketing campaigns we partner with your marketing team or recommend specialists.
Who owns the app source code and intellectual property?
You own 100 percent of the source code, design files, App Store account, signing keys, and operational runbooks. We assign all intellectual property to the client at kickoff. Code is delivered to a client owned repository throughout the engagement.
Do you support clients outside India?
Yes. We work with clients across the US, UAE, Saudi Arabia, Europe, and APAC. Delivery is from India with communication overlap aligned to your time zone. Apps we have built are running in 35+ countries.
How do you ensure mobile app security?
Secure coding standards, certificate pinning, encrypted local storage, biometric authentication, OWASP Mobile Top 10 mitigations, and dependency vulnerability scanning. For regulated industries we implement HIPAA, PCI DSS, or SOC 2 controls.
