Mobile App Development
NXBIRD builds Android and iOS mobile apps for businesses that want to serve customers or teams on their phones. We design the app experience, build a secure backend and help publish the app on the Play Store and App Store.

Cross-platform app vs separate native apps

|---|---|---|
| Codebases | One shared codebase for Android and iOS | One codebase per platform |
| Cost and maintenance | Generally lower | Generally higher |
| Device features | Most common features supported | Full access to every platform feature |
| Good fit | Most business and customer apps | Apps that depend on advanced platform-specific features |

People also ask about mobile app development
How much does a mobile app cost?
Cost depends on scope. Share your requirements and we'll send a written quote. The price depends on the features, integrations, design work and content involved. We explain each part of the quote in plain language before any work begins, so you know exactly what you are paying for.
How long does a mobile app take?
Timelines depend on scope. Share your requirements for a written quote, which includes an estimated schedule with clear milestones. The schedule also depends on how quickly content, access and feedback are available. Larger projects are delivered in stages, so you can review progress before the next stage begins.
What is your process?
We follow four stages: Discover, Design, Build, and Launch & Support. First we understand your goals and agree on scope and cost in writing. Then we plan and design, build in stages with regular updates, test the work and launch it with you. NXBIRD's directors are involved from the first call to launch.
Do you provide support and maintenance after launch?
Yes. After delivery there is a 7-day testing and acceptance period, and bugs or errors you report during it are fixed free of charge. After acceptance, new features or changes are quoted separately, and ongoing support and maintenance are available through an optional annual maintenance contract (AMC).
Who owns the code and designs?
It depends on the plan in your quote. On a managed plan, hosted on NXBIRD's servers, you get your content and admin panel while we manage the server and code. On a full handover plan, source code, design and logins are handed over after final payment. Your content, logo and data always remain yours.
How do you keep the project secure?
Security is planned from the start. We use HTTPS, validate inputs on the server, keep secret keys out of the code, give each user only the access they need and keep software dependencies updated. Personal data is collected only where it is needed and handled with care.
What technology do you use for mobile apps?
We usually build Android and iOS apps from one codebase using React Native and TypeScript, which keeps cost and maintenance lower than two separate apps. The backend runs on Node.js with a MySQL database. If your app needs features that require fully native code, we will discuss it upfront.
Will my app be published on the Play Store and App Store?
We prepare the app, store listing details and builds, and guide you through publishing. The developer accounts should be in your business's name, so you stay in control. Final approval is decided by Google and Apple through their review process, and we help address any feedback they give.
