Mobile app development

Build mobile and cross-platform apps people will never want to delete from their phones

Why go for outsourced mobile app development services

If your customers use mobile (and chances are, they largely do, depending on your target market), you need to make your software service into a mobile app. And whether the mobile app is your core offering or accompanying a web app, you need an experienced mobile app development company to create it with. Especially if mobile app development is not the core skill of your in-house team. And it just so happens that you found one.

The thing with software development companies specializing in mobile application development services (or cross-platform development, but we’ll get to that in a bit), like ours, is that you get so much more than just the development of a mobile app. You often get the whole package – from application design to building the app, to integrating it to work with your existing software and making it easy for you to manage the contents (if that’s what you’re after.)

And if you’re lucky enough, you’ll find people proficient in technologies like React Native or Flutter who can build platforms that will work and look great on any platform. Which means building your desktop or web app and mobile app can happen at the same time, taking up fewer resources and less time – and, of course, a lower budget. 

So,whether your app is simple or complex, intended for consumers or enterprise-class, working with a mobile app development company like DeSmart means you get a fully functional and high-performing software product built with your users and your business in mind. So that it can attract your customers, delight them with a great user experience, and make them happy to use it (instead of making them want to delete your app from their phones at the very thought of opening it.)

And that’s the kind of mobile app we can get you. 

What does mobile app development include?

(If you don’t really need to read the answer to this question, scroll down to learn more about the specific mobile app development services we offer at DeSmart.)

Mobile application development services are usually “a little” more than just coding. You probably know that if you’ve built an app before (or any kind of software, for that matter). And you might not be aware of what goes into the term “mobile app development services” (btw, our SEO person says hi 👋) if you’re just about to build your first software product. In that case, let us give you a quick roundup:

  • We start with the product discovery phase, including elements like impact mapping and business canvases. At DeSmart, we’ll use that time to validate your software assumptions and your business model for your mobile app. We’ll also research your target audience, define the features your users want and need, and suggest the best way to build them.
  • Then we lay the foundations for your mobile app: building the backend architecture, its logic, algorithms, etc. All to make it stable, scalable, and secure.
  • Then it’s time for frontend development to get you high-performing and good-looking mobile apps your users will love interacting with.
  • And UX/UI design services so that they enjoy every time they open the app on their phones.
  • We’ll integrate your mobile app with your web app and other software systems, so you can connect it with your internal software or give your users more options to work with.
  • If we’re doing cross-platform app development, you’ll get a mobile app that also looks and works great on desktop (and vice versa.)
  • We can also grow existing apps with new features, letting you answer your user requests or enter new markets and address new audience segments.
  • Then it’s also quality assurance testing time to evaluate speed, performance, and scalability.

Quite a lot for one little small mobile app, right? Well, a successful mobile app is much more than meets the eye.

What our clients say about our mobile app development services

DeSmart Software Development has succeeded where several other companies have not. I started this project with a certain vision of what I wanted, but no other companies have been able to provide me with what I wanted. With DeSmart Software Development, I have gotten what I wanted and more.
We received a great deal of effort for our money, and I’m happy with our collaboration. The quality of work was professional, and their team identified any bugs by themselves most of the time. Based on the ideas we provided, they came back with an improved solution. They also gave us extra product functionalities.
The initial meeting we had with DeSmart before we started the project was really effective. I recommend doing so if you have the opportunity. Also, their communication, speed of development, and expertise were impressive. DeSmart was excellent at providing their own ideas, which benefited the project greatly.
DeSmart is synonymous with service quality. The company works in a truly agile mode, regularly delivering work increments, which allows to quickly and easily synchronise on requirement details. I was especially impressed with the dev team’s capability to quickly learn and start using our new APIs.
I’d highlight that their ability to adapt is exceptional. We didn’t go with a fixed scope and ended up with a different product than we’d had in mind. They were accommodating of changes and adjustments. That made them very easy to work with. They were also very transparent about pricing, which we appreciated.
I was impressed with their developers' efficiency, speed, and flexibility . Cooperation was smooth and uninterrupted. Monitoring of resource consumption to be improved. Great culture fit. Good value for cost. Company values aligned.


We realize you might not be familiar with all the aspects of the software development process. So here are a few pointers and explanations you might find helpful. And if you have more questions, send us a message, and we’ll get back with the answers.

What are the first steps when we start working together?

1.We always start with consulting your project with our product and business teams to see if we’re indeed a good fit.

2.We’ll then create a cost estimate and a proposed timeline.
Then we’ll organize workshops to help us define the business and product requirements so that we can build the best software solution for your needs. The people who took part in the workshops will make up the foundation of your project team.

3.We sign the contract and set up a kickoff meeting to nail down all the project details.

What are the benefits and drawbacks of the technologies you use?

Our development team will talk you through all the benefits and drawbacks of a specific technology for your specific project so that you know all you need to know to make your decision before you actually make it.
One of DeSmart’s core values is transparency, and we always inform our clients about any risks involved.

Will I work with a dedicated contact person on your team?

This really depends on your requirements. We have project managers, testers, and developers on board, and everyone’s equally involved in the project. This means you can talk directly to the developer working on your software and avoid the usual miscommunication that can happen when information travels through the hands and keyboards of multiple people.

Do you use project management software like, e.g. Jira?

Yes, we communicate using Slack and Jira and try not to use email too much. We’re also open to adjusting to the tools your company uses.

Are you a stable company?

Oh, we are. In the past 19 years, we’ve completed over 200 projects and have a full-time in-house team of about 30 people. We’re also the founding members of – the Polish Software Development Association. Go to to read what our current and past clients have said about working with us.

Why would I want to work with you?

We’re a boutique software house hiring a maximum of 30 people. Among other things, this means that your project is always a priority for us – we just can’t take on too many projects at a time. We’re also super honest and transparent and will always give you a clear picture of what’s going on.

Our team includes experts with many years of experience, and we’re often asked by other software houses to support them with their projects.

We also have a unique company culture. We’re teal-oriented and value a human approach to software development (which is why “Human-first software development” is our tagline) and work in general. And you can see it both in how we run the company and the way we work with our clients.

Why choose cross-platform development for your mobile app?

We’ve already kind of said it, but let us expand (also because our SEO person is always nagging us about not adding enough characters on our landing pages.)

When we build native mobile apps, our services are usually limited to just one platform, like iOS or Android. And maybe that’s precisely what you need. In that case, we’ll assume you’ve done extensive customer research, and you know what devices and platforms your customers use and where you need your app to wor

If, however, your customer research tells you otherwise – and you know people use (or will want to use) your app in different ways and on different devices, going cross-platform is your best bet. Because maybe they’ll use your app on mobile while they’re on their way home from work, but later need to do some more complicated stuff in it on their computer. That’s often the case especially when mobile apps offer just a fraction of the functionality a web app does.

And, sure, you could build separate apps for mobile, desktop, and the web. But you don’t have to be great at math to know this is at least 2-3 times the time, effort, and probably budget.

On the other hand, building an app with a single codebase but working on different platforms means you only build the app once. You do the math.
