Monitoring
We are informing the client about the stages of mobile app development. We are providing a two-week progress report.
-
Responsive design
A user-friendly, intuitive design based on UX/UI principles, with visualizations at the prototype stage.

Result
We test the mobile app. We launch it on the app store and get it to the top of the charts.
Cost and Timeline for Mobile App Development
It is difficult to determine the final cost of developing a mobile app without a preliminary assessment of the product. Typically, both the cost and the development timeline depend on a variety of factors: the functionality of the future app; the platform used to build the mobile app; the complexity of the design; the size of the app (number of pages); the inclusion of e-commerce features; the expected load on the service; the types of supported devices; the characteristics of the target audience; ongoing app support; and marketing promotion.
| Project type | Examples | Screens | Platform | Term | Cost | What’s included |
|---|---|---|---|---|---|---|
| MVP / Startup | Business card, catalog, promotional app | 5-10 | Android or iOS | 1-2 month | from $5,000 | Basic UI/UX, simple backend, 1–2 integrations, testing, deployment, 1-month warranty |
| MVP cross-platform | Business card, catalog Flutter | 5-10 | Android + iOS | 1.5-2 month | from $6,000 | One code base for two platforms, 30–40% cost savings, a basic design, and publication on both app stores |
| Medium-sized project | Online store, delivery service, loyalty app | 15-30 | Android или iOS | 2-4 month | from $15,000 | Custom UI/UX, basic backend, 3–5 integrations (payment, CRM), testing, 2-month warranty |
| A complex project | Marketplace, fintech, service aggregator | 30-50 | Android + iOS | 4-6 month | from $30,000 | Premium UI/UX, complex backend, 5+ integrations, user dashboards, analytics, 3-month warranty |
| VR/AR appendix | Augmented reality, virtual tours, training | 10-30 | Android или iOS | 3-6 month | from $20,000 | 3D modeling, AR/VR engine, performance optimization, device testing |
| Enterprise | Enterprise CRM/ERP, internal systems | 50+ | Android + iOS | 6-12 month | from $50,000 | Full development cycle, integration with corporate systems, training, 3+ months of support |
We’ve been developing apps for iOS, Android, and VR/AR since 2011. Over 50 successful projects. A prototype in two weeks—you’ll see the results before development begins.
Turnkey mobile app development
Turnkey mobile app development is the best option for those who don’t want to go through the hassle and are willing to put their trust in the developers. By specifying just a few parameters and explaining their vision for the app to the developers, the client ultimately receives a finished product with a built-in management system and optimized for various devices, in accordance with the selected service package. Turnkey mobile app development is divided into 5 stages.
-
Stage 1
The initial phase involves gathering the necessary information and approving the technical specifications that the developers will follow.
-
Stage 2
Next, we develop and create prototypes of the most suitable UX/UI design, making the product more appealing and user-friendly.
-
Step 3
This is the main phase, as it involves developing the application’s functionality, designing and building mobile client servers and APIs, writing code to implement the application’s behavior, and integrating the application’s logic with the servers.
-
Stage 4
The developers begin the process of thoroughly testing the functionality of the developed resource, monitoring its stability, and fixing any bugs or errors that are found.
-
Step 5
The app is being released and fully launched online. Going forward, the team will assist the client with technical support and promoting the site on social media and search engines.
Which platform should I choose for mobile app development?
Android
Developing Android apps requires attention to many details. Competition on the Google Play Store is growing, so it’s important to develop mobile apps that can hold their own against the competition. Additionally, keep in mind Android’s unique characteristics, such as the variety of devices, screen resolutions, and operating system versions. These factors require thorough testing and adaptation. User data security is also critically important, and it is essential to implement modern encryption methods and biometric authentication. Finally, to reach a wide audience, support for older versions of Android must be ensured.
IOS
Using the iOS operating system to develop mobile apps for your business offers a wide range of benefits, including enhanced data security and access to a high-spending audience. Investments in iPhone apps pay off faster than those in Android apps, thanks to the larger number of paying users. iOS features a modern security system and high quality standards, making it a reliable choice for businesses.
To develop iPhone apps, our team uses Swift (a programming language), an alternative to Objective-C. It runs 2.6 times faster and produces compact, high-quality code.
Cross-platform applications
A cross-platform app is a program capable of running on both iOS and Android. This hybrid app is available for download on both the App Store and Google Play. Cross-platform apps are built using specialized frameworks, which speeds up development and helps optimize the budget, as it eliminates the need to form separate teams for each platform.
