Mobile app optimization

Is your existing mobile app not performing as well as it used to? We can help you bring it up to current standards so it works optimally with new devices and updated operating systems.

Code refactoring

Are you worried your mobile app code is outdated and overly complicated? We can help you clean it up without affecting its functionality, so it is easier to maintain and is compatible with modern technologies.

Maintenance & support

As part of our end-to-end service, we provide ongoing support so that your mobile app continues to run smoothly, without any bugs. We also implement updates and features based on user feedback.

QA consulting

Ensure your app meets all the standards of quality, functionality, performance, and user experience before and after deployment. Our QA team works closely with the mobile developers to identify issues and improve processes.

Full range of mobile app development services

Product strategy and design

A well-crafted plan before you begin building your mobile application gives it a better chance of success. To that end, we look at the market to identify opportunities and user needs. Then, we use those insights to develop your UX strategy and UI design.

Design and development

Our team of developers are well-versed in the technologies and frameworks we use to develop your mobile app. As a result, we are able to identify the right path for development. Are you not sure whether to go with native or React Native? We help you make the right decisions, not only for your tech stack but also for your budget.

Built-in security

One thing that sets us apart from most other mobile application development services is the fact that we offer cybersecurity testing. This gives us practical insights into what is required for a truly secure app and we pass this knowledge on to you. As an ISO-certified company, we build your digital products with inherent security.

Integration

For mobile apps that are a part of a bigger tech ecosystem or that use microservices to deliver more to consumers, we offer our integration services. We help you access data and features and make them a part of your mobile app experience using custom-built APIs.

Data and analytics

While you do want a product that grows and evolves, doing so without data-driven strategy may not be ideal for your mobile development. That is why we monitor your app’s performance to give you insights that empower you to make strategic decisions and improve your application more efficiently.

Ongoing support

At Infinum, we do not end our collaboration with you the second your mobile application is launched. As part of our full lifecycle app development service, we continue to provide maintenance and support so you never have to worry about fixing bugs or launching updates yourself.

We offer end-to-end development services. That starts with initial planning and strategy, where we listen to you and advise you on what we think is the best tech stack and create an ongoing plan. We then build the application as per your specifications. Once it has been launched, we monitor its performance. If you need updating, supporting, and maintaining, we are here for you. Additionally, we also offer application optimization, code refactoring, and QA services for your pre-existing apps.

For Android applications, we use:  Kotlin Compose Gradle Dagger Coroutines RxJava Our iOS app development is done using: Swift SwiftUI async/await Combine RxSwift SwiftPM CocoaPods If you want cross-platform development, we use: Flutter React Native Kotlin Multiplatform We use these technologies for full-stack development: SWR Angular Material RxJS Nx Ruby PostgreSQL NestJS Java C#

There is no fixed rate we can give you for your development needs as the cost of each project is affected by its scope and technology used. For example, if you want both iOS and Android development, it will cost you more as that will require two separate development teams working on your project. If your app is complex, with many features and integrations, its development cost will be higher than one with one of two simple features. As such, if you want to know how much your app development will cost, get in touch with us and discuss your requirements.

Much like the cost of developing a mobile app, there is no one answer for how long it will take to build. Development time can be affected by the complexity of your app, its structure, and the stages required to build it. Having said that, we do pride ourselves on the speed at which our app developers can get your application built and launched. Again, do speak to us and tell us what you are looking for, and we will give you an estimate of the time it will take.

At Infinum, we are big on communication and constantly keep in touch with you. We’ll send you periodic updates, so that you always know at what stage your project is.

The technology used to build your application depends on factors like app requirements, target audience, and budget. We also consider the operating system for which you are building and whether it requires backend development as well. If you discuss your needs with us, we will help you determine your technology stack.

That is absolutely not a problem. We provide high-quality, clean, and semantically correct code with extensive documentation. You can take it to any other reputable development company and they will be able to work with it. Our aim is not to vendor-lock you; it is to give you exceptional results.

In addition to mobile app development, we also offer custom app development, web app development, product strategy and design, custom IoT solutions, AI solutions, and cybersecurity services for your applications, whether built by us or your own. We’ll even help you out with super app development.
