Native iOS and Android apps
Find out when it's best to choose a native app.
We offer mobile app development services with a special focus on native iOS and Android software. To achieve desirable results, we use Swift and Kotlin. Our native mobile apps guarantee smooth performance even when they offer multiple features based on system components. We customize gestures and navigation elements, so they are adjusted to either iOS or Android standards.
Cross-platform apps
Get to know the benefits of cross-platform app development.
If you want to reach users of Android and iOS devices with one application – choose a cross-platform technology. It’s recommended especially when you want to shorten time to market. At Holdapp, we develop cross-platform apps with Flutter and Kotlin Multiplatform technology.
Native or cross-platform technology:
which is best for mobile app development?
Sometimes, it’s hard to decide what kind of mobile app would be the right choice for your project. This is when the Product Design workshop comes to the rescue. Take part in a session and find out what solutions are recommended in your case.
Mobile app development process
Every mobile app is unique and has to be treated individually. But at the core of each project there’s an optimized development process that allows us to work efficiently and create products that bring real profit to your business. Sometimes, before the app development process begins for good, we recommend conducting Product Discovery workshop to analyze the product vision and improve it.
1
Kick-off & preparations
Before we write the first line of code, we take care of organizational issues. During the kickoff, our team meets the client’s team. We all introduce ourselves and tell others about our roles in the project. Then, we talk about the goals, tasks, and methods that enable us to build the MVP. Among the topics we discuss is also the billing model and the communication between the team members. After this meeting, our app developers analyze the project scope and identify the risks. Then, they choose the right tools. At the end, the team prepares the initial version of the backlog.
2
Design
It’s an optional stage in a product development process when we prepare a UI/UX design. We conceive the projects based on wireframes, personas, or other tools that help us create both functional and aesthetically pleasing designs.
3
Development & testing
We work in iterations, according to agile development guidelines. Over the course of one iteration, the team meets every day and exchanges the info about the current status of progress. When the iteration is finished, a quality assurance specialist tests the product. We also conduct retrospective meetings to discuss what worked well and what needs to be improved. With us, you’re always kept in the loop. We regularly show you what we’ve developed, so you can see if the project moves in the right direction.
4
Product release
We take care of the entire distribution process, so you don’t need to do it all by yourself. It’s on us to make sure your mobile applications meet all the requirements Google Play and Apple App Store have. We’ll let you know what legal and marketing materials you should prepare. We can also advise you on ASO-related issues.
5
Maintenance
Think of this stage as a second part of the development & testing phase. This is when our mobile app developers improve the product, make sure it’s stable, and add new features. When the new version of the application is tested and ready to go, we get back to the Product Release stage and begin the distribution process on Google Play, Apple App Store or Huawei AppGallery platforms.

About our mobile app development services
Why choose our software development company?
Our team has been creating mobile apps since 2012. We have only accomplished developers on board, with at least 4 years of experience in software development. So, if you decide on creating your app with us, you can rest assured that the project is in good hands.
We’re the app development company that likes challenges and out-of-ordinary projects. This approach allows us to make software that gets recognized not only by our clients or users. Our apps have been nominated for the Mobile Trends Awards – Answear in 2017 and DaNoize in 2020. We’ve also developed the award-winning mobile app for a sports betting company forBET.
What do we offer as a part of mobile app development services?
We do our best to answer clients’ needs, so we offer a comprehensive approach to mobile app development. If you want to polish your idea for an application, we can run a Product Design workshop for you and your team. Additionally, our specialist can also prepare UI/UX designs.
Our main field of expertise is mobile app development – we specialize in building native iOS and Android apps. We also develop applications for two platforms with Flutter and Kotlin Multiplatform (KMP).
As a mobile app development company that considers quality a priority, we offer QA services. Our testers carefully check all our products before they get published on the app stores.
Project management is another service we offer that helps us work efficiently. If you decide to develop a mobile app with us, we can either assign you a dedicated project manager or our software developer can become a technical coordinator, instead.
Pricing models for mobile app development
We often cooperate with clients based on a time and materials model but sometimes, we also sign a fixed price contract. The latter is usually recommended when you want to develop an MVP or your budget is limited.
Times and material is a more flexible model that increases the chances to build a top-tier, marketable product but it’s less predictable when it comes to budget and deadlines.
Here you can find more info about these two billing models that can help you choose the best one for your project.
Efficient cooperation even in different time zones
We’re a software development company based in Europe. We have our office in Poland but we cooperate with clients from all around the world. Even if team members live in different time zones, we can adjust our meetings accordingly, so everyone could be actively involved in a mobile app development process.
