Your search ends here! Rainstream is the leading mobile app development agency in the UK, trusted by brands globally. We design high-performing mobile apps that drive success for your business. Our comprehensive mobile services include:
We comprehensively define and refine your app idea through competitive research, key performance indicators, and analytics. Our team thoroughly analyses your specific requirements, including target audience, technology stack, user workflow, and required features.
We plan the user experience, design mockups, and user interface with prototypes to ensure everyone in the team is on the same page. Our team then starts with app development using advanced technologies and frameworks.
We rigorously test the mobile app with automation and manual testing processes to ensure its functionality, usability, and scalability. Even after the launch, we offer maintenance and support services to fix errors and improve the architecture.
Deciding between a custom mobile app and off-the-shelf mobile applications can be tricky. While a custom app gives you exclusivity and flexibility, an off-the-shelf app provides quick deployment and cost savings.
| Feature | Custom Mobile Apps | Off-the-Shelf Mobile Apps |
|---|---|---|
Use Case | Ideal for businesses with unique workflows | Suitable for businesses that need a quick, ready-made solution |
Control & Scalability | Offers complete control and scalability | Cost-effective for those with a limited budget. |
Integration | Enables smooth integration with existing tools | Works well with standard pre-defined processes. |
Security & Privacy | Provides advanced security and data privacy options for users. | Best for testing new ideas or a Minimum viable product (MVP). |
User Experience | Delivers personalised user experience for long-term growth. | Comes with a fixed set of features and regular updates. |
A stand-alone mobile application cannot ensure long-term success. It requires complementary web development services to manage critical components such as admin dashboards, content management systems (CMS), API, and landing pages.
The cost of developing a mobile app in the UK may range from £10,000 to £150,000 or more. However, it may further increase or decrease depending on several factors:
App typeDesigning a basic app focused on displaying content based on user input is affordable, while further integration with advanced features like AI, real-time tracking and secured payment gateways may increase the cost.
UI/UX StrategyBuilding a mobile with a simple UI may cost low, but if you are aiming to provide a highly engaging user experience with custom animations and intuitive workflows, expect a higher investment.
PlatformDeveloping native apps for Android or iOS may cost more because of separate codebases and platform-specific optimisations.

Selecting between a native and a hybrid app is a key decision that directly impacts cost, performance, and user experience. While a native app is platform-specific (Android or iOS), a hybrid app runs across multiple platforms using a single code base. Here’s a quick comparison to help UK-based businesses decide what suits them best:
Native mobile applications deliver faster load times, while hybrid apps may display slight delays due to their web-based core.
Hybrid apps are cost-effective as they require one codebase, whereas native apps are costly as separate coding efforts are involved in the development.
Hybrid apps are quick to deploy across platforms, while native apps take a longer time due to platform-specific requirements.
Native mobile apps offer a rich and more responsive user interface customised to the operating system (OS), while hybrid apps provide a uniform but less intuitive user experience.
Native apps have complete access to advanced device features like camera, GPS, and biometrics, while hybrid apps' feature access is limited or is dependent on the plugin.
Native apps require separate maintenance for each platform, whereas hybrid app updates are simple due to a single code structure.
