Nautilus Techlabs — Top Flutter & Mobile App Development Company Worldwide

Every app is unique, which means every budget is too. The cost depends on multiple factors: your app's features and functionality, design complexity, platform choice (iOS, Android, or both), third-party integrations, and development timeline.

Our approach is transparent: we start with a detailed discussion of your requirements and objectives, then provide a comprehensive estimate broken down by features and development phases. This way, you know exactly what you're paying for and can prioritize features based on your budget. We believe in no surprises, just honest pricing based on real project scope.

Development timelines vary based on your app's complexity and feature set. Simple apps with basic functionality typically take 2-3 months, while complex apps with advanced features can take 6-9 months or more.

Here's our process: Once we understand your requirements, we create a detailed project roadmap with clear milestones. We start with a one-month sprint to give you concrete progress and a refined timeline estimate. Plus, we offer a two-week trial period if you're not satisfied with our work, you can exit the project with no penalties. This ensures you're confident in our capabilities before fully committing.

Absolutely, yes. We understand your app concept is valuable intellectual property that needs protection. Before diving into any project specifics, we're ready to sign a mutual Non-Disclosure Agreement (NDA) to legally safeguard your information.

Confidentiality isn't just a legal obligation for us; it's a core principle. Every conversation, document, and piece of information you share stays strictly between us. Your ideas deserve protection, and we're committed to providing that security from day one.

We offer both approaches and help you choose the right one for your specific needs:

Native Development: We build separate apps for iOS (Swift) and Android (Kotlin/Java). This approach delivers maximum performance, seamless integration with device hardware (camera, GPS, sensors), and the most polished user experience. It's ideal for apps requiring intensive graphics, complex animations, or platform-specific features. The tradeoff? Higher cost and longer development time since we're building two apps.

Cross-Platform Development: Using Flutter, we write one codebase that works on both iOS and Android. This cuts development time and costs by nearly half while still delivering excellent performance for most use cases. It's perfect for MVPs, business apps, and projects with tight budgets or faster launch deadlines.

During our consultation, we'll analyze your app's requirements, performance needs, and budget to recommend the optimal approach. Sometimes, we even suggest a hybrid strategy using native for specific features and cross-platform for the rest.

Transparency is built into our workflow. You'll receive daily standups from your development team quick updates on what was completed yesterday, what's planned for today, and any blockers we're facing. At the end of each week, you get a comprehensive report detailing completed work, upcoming sprint goals, and overall project progress.

But we don't stop there. You have open communication channels via Zoom, Slack, or email whenever you need clarification or want to discuss the project. We believe in real-time collaboration, not just periodic updates. You're never left wondering what's happening with your project.

Simple answer: You own everything, 100%. Once the project is delivered and final payment is processed, you receive full ownership of the source code, design files, technical documentation, and all project-related assets. There are no strings attached.

You're free to modify the code, hire another team for future updates, or do whatever you wish with your app. We don't retain any rights to your intellectual property. The only thing we ask for (with your approval) is permission to feature the project in our portfolio as a showcase of our work, but even that's optional and entirely your decision.

Launch day isn't the end—it's just the beginning. We offer ongoing technical support and maintenance packages to keep your app running smoothly. This includes bug fixes, performance monitoring, OS compatibility updates (when Apple or Google releases new versions), security patches, and minor feature enhancements.

If you prefer to handle maintenance in-house, no problem. We'll hand over the complete source code and detailed technical documentation so your team can take over seamlessly. Even after handoff, our door remains open if you run into technical challenges or need guidance, we're just an email away. Your success is our success, and we're invested in your app's long-term performance.

Yes, we handle the entire app store launch process for both the Apple App Store and Google Play Store. This includes:

• Setting up or managing your developer accounts
• Creating compelling app store listings (descriptions, keywords, screenshots, promotional graphics)
• Ensuring your app meets all platform guidelines and compliance requirements
• Submitting your app for review
• Managing communication with Apple/Google review teams
• Address any rejection feedback and resubmit until approval

App Store approval can be tricky with constantly changing guidelines, but we've launched hundreds of apps and know exactly what reviewers look for. We'll guide you through every step and handle the technical headaches so you can focus on your app's launch marketing. Even post-launch, we can manage your app updates and version releases.

Of course! We're proud of our talented team and happy to share their credentials. Simply reach out through our contact form or email with details about your project requirements, preferred technologies, and any specific expertise you're looking for.

We'll respond with detailed profiles of team members whose skills align with your project needs. You'll see their educational background, years of experience, technical specialisations, previous projects, and certifications. Transparency about who's building your app is important. You deserve to know the expertise behind your project.

We offer flexible engagement models to match your needs. Contact us with your project requirements, preferred tech stack, and timeline. Based on this information, we'll share profiles of developers whose expertise matches your needs.

You can review candidates, review their portfolios,and even assign a test task to evaluate their skills before making a decision. We offer multiple hiring options:

• Dedicated developers for long-term projects (monthly contracts)
• Part-time developers for smaller scopes or ongoing support
• Full project teams (developers, designers, QA) for comprehensive solutions
• Trial periods to ensure the right fit before long-term commitment

Pricing and contract terms are flexible based on engagement duration and team size. We're here to find an arrangement that works for your project and budget.
