Custom Android App
Custom Android development in Kotlin or Java, matched to your business logic, not a template. From a simple storefront to an app with a full admin panel.
From idea to your customer's phone
Custom app development; when a website alone isn't enough anymore
After growing, many businesses need something beyond a website: an app on their customer's phone, a bot that answers automatically, or custom software for internal processes. We design and code all of these from scratch, matched to your business's real needs, with serious security standards.
- Custom code (not an off-the-shelf template)
- Support after the store launch
- Tech stack chosen to fit your budget
- Security at every layer of the app
RGB App Development Services
From mobile apps to bots and bespoke software, every app development service your business needs to grow beyond a website:
Custom iOS (iPhone) App
Native development in Swift for a smooth experience that matches Apple's standards; the right choice for businesses with an iPhone-focused audience or a quality-first priority.
Telegram & Instagram Bots
Automated replies, order-taking, customer follow-up, and smart messaging; a bot that handles part of your support and sales work without ever getting tired.
Custom Web & Software Development
Development in PHP, Python, Java, C#, and Swift for internal systems, admin panels, or software that no off-the-shelf template can handle.
Database Design & Management
Database architecture on MySQL or SQL Server, query optimization, and network architecture design; infrastructure that stays stable under real load.
Blockchain & Smart Contracts
For specific projects that need transparency and decentralization; smart-contract development and blockchain-connected apps, with honest technical advice on real-world use cases.
Native or cross-platform: which is right for your business?
This decision directly affects cost, delivery speed, and the final quality of the app, and the right answer differs for every business.
Native development, Swift for iOS and Kotlin for Android, gives the best performance and OS integration; but it means two separate development efforts, and more cost and time to cover both platforms. Cross-platform development, by contrast, runs one shared codebase across Android and iOS; delivery is faster and more cost-effective, but features tied to phone hardware (advanced cameras, sensors) can carry minor limitations.
Before recommending a path, we ask what the app needs to do, your real budget and timeline, and whether you need advanced hardware capabilities or not. For an app built around content and simple forms, cross-platform is usually the more sensible call; for an app where performance and user experience are the top priority, we recommend the native route, even if it costs more. Our goal isn't selling you the most expensive option; it's getting you to the one you actually need.
Our app development process at RGB
Every app development order goes through these 5 stages; transparent, documented, and trackable at every step:
1
Requirements analysis and documentation
A discovery session: we listen closely to the app's purpose, end users, must-have features, and budget, and write it all up in a technical document that becomes the project's single reference.
2
UI/UX design in Figma
Before a single line of code, the user experience and visual interface are designed in Figma, so the user's path through the app is clear and something you can approve.
3
Architecture and tech stack selection
Based on the project's real needs, we decide between native or cross-platform development, and the right language and framework (Kotlin, Swift, or a shared stack).
4
Coding and testing
App development in short cycles, along with performance, security, and compatibility testing across different devices and OS versions.
5
Store release and support
Registration and release on Google Play or the App Store per each platform's rules, and regular support and updates after launch; our work doesn't end at delivery.
Why trust RGB with your app development?
The same security, on your app too
The same website security standard we run also applies to apps; from data storage to secure server communication, security is part of the coding itself, not an extra step tacked on at the end.
A natural companion to your site
Many of our clients started with a website design project and now need an app alongside it; since we already know your infrastructure and business logic, this path moves faster and stays more consistent for you.
Support after launch
Unlike a brochure, an app needs updates, bug fixes, and compatibility work with new OS versions even after release; this support is part of our commitment, not a hidden cost later.
App Development Pricing & Bot / Custom Software Rates
App development pricing doesn't have a single fixed number, and that's entirely normal. The final rate depends on the number of pages and sections, the complexity of features (payments, maps, notifications, and similar), and the chosen platform (Android, iOS, or both). Instead of throwing out misleading figures, we issue a transparent quote for your specific project after a short, free requirements session.
Prices are shown in US dollars and stay fixed regardless of exchange-rate swings — no need to call for the "real" price.

Everything you should know before ordering app development.
How much does app development cost?
It depends on the number of pages, the complexity of features (payments, maps, notifications, and so on), and the chosen platform (Android, iOS, or both). After a short, free requirements session, you get a transparent quote with an itemized cost breakdown.
What does the app development ordering process look like?
It starts with a requirements session, then UI/UX design in Figma, tech-stack selection, coding and testing, and finally store release. You get a progress report at every stage and your approval is required.
Does app development cover Android and iOS at the same time?
Yes. Depending on your needs and budget, we can develop both platforms natively and separately, or with a single cross-platform codebase; we make this decision with you after explaining the pros and cons of each.
How long does building an app take?
For an app with moderate features, usually 4 to 8 weeks; simpler bots take less time. Complex custom systems and software have their own timeline depending on scope, determined precisely during the requirements session.
Do you provide support and updates after the app launches?
Yes. After release, an app needs bug fixes, compatibility work with new Android and iOS versions, and sometimes new features. This support is part of our service, and we discuss it transparently before the project starts.
What's the difference between an app and a Telegram bot?
An app is a standalone program the user installs and opens from their phone's icon; you have full control over its design and features. A Telegram or Instagram bot runs inside another platform, launches faster and cheaper, but depends on that platform's rules and limits. The right choice depends on your goal and budget.
