How long does it take to build a mobile app?

Most MVPs take 4-8 weeks from kickoff to launch. More complex apps with integrations, custom backends, or compliance requirements typically take 14-20 weeks. We'll give you a realistic timeline during our initial consultation — we don't overpromise to win the deal.

How much does mobile app development cost?

We offer competitive European rates without compromising on quality: Simple apps (basic features, single platform): ~$9,360 – $17,550 Medium complexity (user accounts, payments, API integrations): ~$17,550 – $40,950 Complex apps (real-time features, multiple integrations, admin dashboards): ~$40,950 – $70,200 Enterprise solutions (compliance requirements, advanced security, legacy system integration): $70,200+ We provide detailed fixed-price quotes after understanding your requirements, no surprises in the middle of the project. With 13+ years of experience and 300+ delivered projects, we know how to scope accurately.

Do you build for both iOS and Android?

Yes. We typically use cross-platform frameworks like React Native or Flutter, which let us build for both platforms simultaneously. This reduces cost and development time by 30-40% compared to building two separate native apps.

What industries do you work with?

We don't specialize in one industry. Over the past 13 years we've built apps for e-commerce stores, SaaS startups, HR companies, hotels, B2B platforms, and more. If you need a mobile app, a web platform, or custom software that actually works in production, we can probably help. The common thread is clients who need reliable delivery, not the cheapest quote.

What does your development process look like?

We work in 2-week sprints. At the end of each sprint, you see working software, not slides or mockups. You'll have a dedicated point of contact, access to our project management tools, and bi-weekly demo calls. No disappearing for months and hoping for the best.

Will I own the source code?

Yes, 100%. You own everything we build including source code, documentation, designs, deployment configurations. No licensing fees, no lock-in. If you want to take the code to another team tomorrow, you can.

How do you handle communication?

You'll have direct access to the engineers working on your project and not just a project manager relaying messages. We use Slack for day-to-day communication and scheduled video calls for demos and planning. Most questions get answered within a few hours during business hours.

What if I need changes after launch?

We offer ongoing support and maintenance packages, but you're not locked in. Since you own the code and we document everything, any competent development team can pick up where we left off.

What technologies do you use?

Mobile:React Native, Flutter, Swift (iOS), Kotlin (Android), Unity Engine and sometimes just WebView Web: PHP ,React, Next.js, Node.js, Python Backend: AWS, Google Cloud, PostgreSQL, MongoDB We choose the stack based on your needs, not what's trendy. We'll recommend what makes sense for your timeline, budget, and long-term maintenance.

Can you work with our existing codebase?

Yes. We regularly take over projects from other teams. We'll start with a code audit to assess what's salvageable and what needs rebuilding. We'll be honest sometimes it's faster to rebuild than to fix.

Do you handle UI/UX design?

Yes. Our design team handles user research, wireframes, prototypes, and final UI design. Good design isn't optional apps that look dated or are hard to use don't get traction, no matter how solid the code is.

How do you ensure app security?

Security is built into our process, not bolted on at the end. We use encryption for data at rest and in transit, secure authentication, and follow OWASP guidelines. For healthcare or financial apps, we can implement HIPAA or PCI-DSS or WCAG or GDPR compliance requirements.

How do I know if we're a good fit?

We work best with clients who: - Have a clear business problem they're trying to solve - Are ready to invest in quality (not looking for the cheapest option) - Want to be involved in the process, not just hand off requirements and disappear - Need software that works reliably in production

What do you need from me to get started?

For an initial consultation, just a rough idea of what you want to build and your goals. We'll ask questions to fill in the gaps. For a formal proposal, we'll need more detail but we'll guide you through that process.

How do I get a quote?

[Contact us](/contact) with a brief description of your project. We'll schedule a 30-minute call to understand your needs, then follow up with a detailed proposal within 3-5 business days.

What if I'm not happy with the work?

We demo working software every two weeks. If something isn't right, we catch it early and fix it not three months later when it's expensive to change. If there's ever a fundamental disagreement, you own the code and can walk away.

What if my requirements change mid-project?

They will, that's normal. Our sprint-based process is designed for this. We'll discuss the impact on timeline and budget, and you decide whether to proceed. No change requests disappear into a black hole.

What happens if a key team member leaves?

We have engineering teams across multiple locations and other regions, so there's always someone ready to step in. We document everything properly and use standard code practices, so knowledge doesn't get stuck in one person's head. In 13 years, we've never had a project stall because of team changes.

How does pricing work?

We offer two models: 1) Fixed-price projects: Best for well-defined scopes. You know the total cost upfront. 2) Time & materials: Best for evolving projects. You pay for actual hours worked, with full transparency. Most clients start with fixed-price for the MVP, then move to time & materials for ongoing development.

What are your payment terms?

Typically 30-40% upfront, with remaining payments tied to milestones. We don't ask for 100% upfront, and we don't invoice for work you haven't seen.

Do you offer payment plans?

Yes. We can structure payments across the project timeline to help with cash flow. Let's discuss what works for your situation.

AI Legal Intelligence Platform for Romania

Building an AI Legal Intelligence Platform for Romanian Compliance Monitoring

L Lexmonitor is an AI-powered legal intelligence SaaS that watches ANAF, Monitorul Oficial and BPI in real time, so law firms and compliance teams in Romania stop losing hours to manual searches.

Numeris Activ Consult partnered with Five Quantum Bits to solve a concrete pain: lawyers, accountants and compliance officers were manually scanning the Official Gazette, insolvency bulletins and ANAF records every week to catch changes affecting their clients. Lexmonitor replaces that routine with an AI legal intelligence platform that ingests Romania's official legal and fiscal sources, matches each publication against the user's monitored portfolio, and uses a trained AI assistant to answer natural-language questions over the user's own documents, files and alerts. The dashboard surfaces monitored companies, active files, new alerts, documents analyzed, ANAF indicators and a weekly AI summary that explains, in plain Romanian, what actually changed.

Project Summary

Lexmonitor was engineered by Five Quantum Bits as a production-grade AI legal intelligence platform tailored to Romanian compliance. The system continuously syncs with the official ANAF API and ingests publications from Monitorul Oficial and the Buletinul Procedurilor de Insolvență, then correlates every entry with each user's portfolio of monitored companies and files. On top of this ingestion layer runs a trained AI assistant that answers questions over the user's own documents, files and publications, and produces an automated weekly summary describing what changed and what did not. The UX was designed for clarity: a left-side navigation covering Societies, Files, BPI, Official Gazette, Documents, Notes and the AI Assistant; a dashboard overview with monitored companies, active files, new alerts and documents analyzed; and a mirrored mobile experience for lawyers and consultants working outside the office. The outcome is a focused legal AI SaaS that converts hours of manual checking into a single trustworthy source of truth, delivered on scalable cloud infrastructure with team management and admin controls built in from day one.
