Mobile App Development Company in Berlin

We are not headquartered in Berlin, but we work with Berlin clients across tech, FinTech, and manufacturing on remote engagements with five to six hours of daily CET morning overlap. QServices is a remote-first software consultancy serving German businesses that need production-ready iOS and Android applications built to EU compliance standards.

What Berlin buyers typically need from mobile app development

Berlin's mobile app requirements cluster around three of its primary industries, each with distinct technical and compliance needs:

• FinTech startups and scale-ups: Payment apps, digital wallets, and lending platforms that must satisfy BaFin licensing requirements and EU GDPR data-handling obligations. KYC onboarding flows, PSD2 open banking integrations, and strong customer authentication (SCA) are standard requirements in this sector.
• Tech companies: B2B SaaS mobile companions, internal tooling, and consumer applications. React Native covers most cross-platform needs; native Swift or Kotlin when performance-critical features demand it.
• Manufacturing firms: Warehouse management, field service, and quality inspection apps. Typically Android-first, offline-capable, and integrated with existing ERP systems via REST or direct API connectors.

Every app we build for EU clients is designed with GDPR compliance from the first sprint: data minimization by default, explicit consent flows, right-to-erasure support, and EU data residency where required. For Berlin FinTech clients specifically, we account for BaFin notification obligations when building apps that touch regulated payment or lending flows. This is not an add-on we bolt on at the end, it shapes the data model and API design from day one.

How we work with Berlin clients

Our engineering team is based in India on IST (UTC+5:30). Berlin runs on CET (UTC+1 in winter, UTC+2 in summer), which puts India 4.5 hours ahead of Berlin in winter and 3.5 hours ahead in summer. A Berlin team starting at 9:00 AM CET has our full team available through roughly 2:30 PM their time, five to six hours of live overlap each working day, without requiring either side to work early mornings or late evenings.

We structure every engagement around that window:

• Weekly 45-minute video standup scheduled at 10:00 AM CET, built around your calendar
• Async sprint updates posted before end of day IST, arriving in Berlin inboxes before the working day starts
• Pull request reviews completed within the same business day on GitHub or Azure DevOps
• Fortnightly demo calls, recorded, with written notes shared within 24 hours

We use Teams or Slack, whichever your team already uses. On-site visits to Berlin are possible for contract signing or major milestone reviews, charged at cost and agreed during scoping. For most projects, the overlap window is sufficient and on-site visits are not required.

Relevant work in similar markets

We have not built apps for Berlin-based clients. Our closest relevant work is in financial services mobile, which aligns directly with Berlin's FinTech sector, rather than the Berlin market itself. We want to be clear about that distinction.

The SomBank engagement was a React Native payment platform handling P2P transfers, merchant QR payments, and international remittances, built for an Islamic bank in Somalia. It launched with over 100,000 downloads and a 4.8-star rating. The architecture, Ocelot API gateway, Azure Service Bus for message reliability, Azure Key Vault for secrets management, Azure B2C for identity, maps directly to what a Berlin FinTech building a regulated consumer payment app would need. The compliance constraints were different (Somali banking regulation, not BaFin), but the engineering discipline is the same.

The Chikwama digital wallet introduced real-time P2P transfers to a cash-dependent market using SignalR for live transaction updates. Both projects were built under financial services constraints where data integrity and audit trails were non-negotiable, not unlike what BaFin expects from licensed payment apps operating in Germany.

What mobile app development costs for a typical Berlin project

Our rates are in USD. EUR/USD conversion applies at the prevailing market rate; we do not adjust quotes for currency fluctuations. Typical ranges for mobile app projects:

• Small scope ($35,000–$60,000): Single-platform MVP (iOS or Android), core feature set, App Store or Play Store submission handled, basic analytics and crash reporting from day one. 12–16 weeks.
• Medium scope ($60,000–$120,000): Cross-platform React Native app, backend API, third-party integrations (payments, auth, push notifications), analytics from day one. 16–20 weeks.
• Large scope ($120,000–$200,000): Full platform with multiple user roles, regulated payment flows, complex system integrations, or device hardware dependencies. 20–24 weeks.

For Berlin FinTech clients, add 15–25% for BaFin-adjacent compliance scope: audit logging, encrypted key storage, consent management documentation, and the additional review cycles that regulated work requires. Each non-trivial system integration, a banking API, an ERP connector, a third-party KYC provider, adds $3,000–$12,000. See our mobile app development pricing page for a full breakdown. If your project touches financial services, our mobile apps for FinTech page covers the compliance considerations in more detail.

Do you work with Berlin companies remotely?

Yes. All our Berlin engagements are fully remote. We have no physical office in Germany. The CET-to-IST gap, 4.5 hours in winter, 3.5 hours in summer, leaves five to six hours of live overlap each working day. That is enough for synchronous decision-making, code reviews, and sprint demos without unusual hours for either team.

For GDPR data residency: if your project requires EU data storage under Articles 44–46, we build on Azure West Europe (Amsterdam) or Azure Germany West Central (Frankfurt) by default. We do not transfer EU user data outside the EU unless the client explicitly waives this in writing. Production access goes through role-based controls and VPN with full audit logging. For BaFin-regulated apps, we can supply a written technical security document to support your due diligence process.

How to start working with us

Three steps from first contact to project start:

1. Discovery call (30 minutes): We ask about your app concept, target users, platform requirements, and any compliance obligations specific to your industry. No sales pitch, just questions and answers.
2. Scoping document: We produce a written feature breakdown, recommended tech stack, timeline, and a fixed-range cost estimate. Takes 3–5 business days and is free.
3. Project start: Once the scope is agreed, your core team is assigned, project tooling is configured, and the first sprint begins within two weeks.
