Custom Mobile App Development Services

We develop native apps for iOS and Android, hybrid apps, cross-platform apps, and PWAs. This includes consumer-facing apps, enterprise solutions, and specialized tools across fintech, healthcare, ecommerce, on-demand, IoT, and more, depending on your requirements.

Native apps are built specifically for one platform using platform-specific languages, offering the best performance and UX. Hybrid apps are built with web technologies to run on multiple platforms, making them more cost-effective for content-driven apps. We'll recommend the approach that fits your performance, budget, and timeline.

It depends on where your users are and your budget. If your audience skews iPhone, which is common in the US and for premium or enterprise apps, an iOS-first launch can be the smart move. Android leads globally and in many emerging markets. 

Most clients ultimately want both, which is where cross-platform development (React Native or Flutter) pays off: one codebase ships to both stores with a native feel, for less than the cost of two separate native builds. We help you weigh reach, performance, and cost during scoping, then recommend whether to go native or cross-platform for your case.

Evaluate proven, relevant apps shipped;

• tech-stack fit (Swift, Kotlin, React Native, Flutter)

• Communication and project management

• Security and compliance experience (HIPAA/GDPR/SOC2)

• Post-launch support

• Total value over the lowest price.

Ask who owns the code, how they handle app-store submission, and how they keep the app secure. (We're happy to answer all of these.)

You have three routes:

• Freelancers (cheapest, but you manage everything and carry the risk)

• In-house hires (full control, but slow and expensive to staff)

• Development partner like DBB Software (a vetted senior team, accountable for delivery, available now).

Whichever you choose, check the apps they've shipped in your domain, confirm who actually owns the architecture, and verify their security and compliance experience. If you'd rather scale your own team than outsource the whole build, you can also hire mobile app developers from us to work as an extension of your in-house staff.

Every engagement starts with a signed NDA, before you share anything sensitive. Your ideas, designs, code, and data stay confidential; you own all the IP; and we never reuse your concept or compete with it. For extra peace of mind, we can structure the work so that the most sensitive pieces are shared on a need-to-know basis.

The timeline depends on complexity, but a complete app usually takes 2-4 months. With DBB Software's mobile app development services, you can launch sooner through our architect-led, AI-accelerated delivery, where senior engineers review every output, so speed never costs you quality. We can deliver an MVP in as little as 12 weeks.

Per industry averages, a mobile app typically costs between $15,000 for a simple single-platform app and $150,000 or more for a complex, multi-platform product; the spread depends on the number of platforms, app complexity, integrations, and security/compliance needs, which drive most of that spread. 

Custom work doesn't fit a fixed price list, so rather than quote a misleading number, we scope your project and provide a tailored estimate after an initial consultation (our website assistant can give you a quick ballpark in the meantime). We favor an MVP-first approach to control upfront cost.

Yes, security is built in. We follow OWASP Mobile practices, including secure storage, encryption, and MFA/SSO, and have experience meeting HIPAA, GDPR, PCI DSS, and SOC 2 requirements for regulated apps.

Yes. You own all the source code, design assets, and intellectual property, with full rights transferred to you. There's no vendor lock-in: you're free to host, extend, or move the app to another team whenever you want. We build every app to be handed over, with clean, documented code in a repository that's yours.

Absolutely. We build apps tailored to your existing infrastructure and seamlessly integrate them with your systems and third-party services via documented APIs, webhooks, and SDKs.

Yes. We manage the full release: store-ready metadata, screenshots, privacy labels, and the review process for both the Apple App Store and Google Play, and we build to pass review the first time. We publish under your developer accounts, so you keep ownership (or help you set them up), and our CI/CD pipelines make post-launch updates fast.

We do through a dedicated team or a retained support contract:

• Monitoring

• OS-update compatibility

• Security patches

• App-store resubmissions

• New features as your product evolves.
