From idea to Google Play and the App Store: we design, build and launch secure, scalable Android, iOS and cross-platform apps for startups and enterprises.
250+ projects delivered
Gamostar is a mobile app development company with 10+ years of experience building Android apps, iOS apps and cross-platform apps for startups, enterprises and gaming brands worldwide. We handle the whole journey — discovery, UI/UX design, development, testing, store launch and long-term support — so you work with one accountable team.
Whether you need a custom mobile app for your business, an MVP to test an idea, or a large multi-role platform with an admin panel and payments, we choose the right technology (native Kotlin / Swift, Flutter or React Native) for your goals, budget and timeline.
Our apps are built with clean architecture, secure APIs and automated testing, and we hand over the full source code. After launch we keep them fast, compatible with every new Android and iOS release and improving with real user data.

One codebase for Android and iOS with Flutter or React Native — faster and more affordable.
Research-backed, conversion-focused interfaces with clickable prototypes.
Scalable Node.js / cloud backends, real-time features, payments and admin dashboards.
Bug fixing, OS updates, performance tuning and new features after launch.
Shopping apps with catalog, cart, payments and push offers.
Delivery, taxi and home-service apps with live tracking.
Telemedicine, workout and wellness apps with wearable sync.
Real-time multiplayer, card, casino and social games.

Not sure which to choose? We recommend the best option after a free discovery call, based on your features, audience and budget.
| Project type | What is included | Typical timeline |
|---|---|---|
| MVP / first launch | Core features, one platform or cross-platform build, basic admin panel | 8–12 weeks |
| Full-featured app | Complete feature set, Android + iOS, advanced admin, integrations, analytics | 4–6 months |
| Enterprise / marketplace | Multi-role platform, custom workflows, high-scale backend and compliance | 6 months and more |
Timelines depend on scope, integrations and how quickly feedback is shared. We confirm exact effort and cost after a short discovery call.
A senior team that has delivered 250+ games, apps and platforms for startups and enterprises worldwide.
Weekly demos, a shared task board and clear milestones — you always know what is happening.
NDA before we start, encrypted data, secure APIs and best-practice authentication.
Full source code, design files and documentation are handed over to you.
Bug fixing, OS-update compatibility, monitoring and feature upgrades under flexible plans.
We work with clients across India, the USA, the UK, Europe and the Middle East.
We study your idea, audience and competitors, then define scope, features and a realistic roadmap.
Clickable prototypes and a polished, conversion-focused interface that you approve before development.
Short sprints with weekly demos, clean code, secure APIs, payments and third-party integrations.
Real-device testing, performance, load and security checks before every release.
Store or server launch, monitoring and ongoing maintenance after go-live.
A defined scope, timeline and price. Best for MVPs and well-documented requirements.
Developers, designers and QA working only on your product, on a monthly basis.
Flexible hourly engagement for evolving scope, audits and ongoing improvements.
Cost depends on features, platforms, design complexity and integrations. A focused MVP costs much less than a full multi-role platform. Share your requirements and we send a free estimate within 24 hours.
An MVP typically takes 8–12 weeks and a full-featured Android + iOS app 4–6 months, depending on scope and feedback speed.
Choose native for maximum performance and deep device access. Choose Flutter or React Native to launch on Android and iOS faster and at lower cost from one codebase.
