The Scope of Our Application Development Services
App planning
We elicit business needs and concerns, draw up functional and technical requirements for a new software solution. We can also help with idea productization and brand design.
Business case creation
We estimate the expected TCO and ROI of the application, explore ways to optimize the app development and maintenance costs.
Project planning
We prepare a development and management roadmap with a release plan, a prioritized feature list, deliverables at each stage, risk mitigation steps, and more.
App architecture design
We describe app architecture, tech stack, compliance strategy, design development and production infrastructures.
App UX/UI design
We conduct UX research and create wireframes and dynamic prototypes. After that, we conduct user testing and prepare full-color graphic interface mockups.
App development
We set up CI/CD pipelines, build the server side, the client side and APIs. We conduct regular code reviews and run all kinds of required tests in parallel with development.
App QA & testing
We plan and conduct functional (including integration and regression), exploratory, performance, usability, compatibility, security tests. We set up test automation, if needed.
App support and evolution
We manage app performance and security, provide L1–L3 support, help optimize TCO. We plan and add new integration and features, including advanced capabilities (e.g., AI, AR/VR, video streaming).
App migration
We recode/re-architect the app (if needed), plan and perform migration to the cloud, test the migrated apps and the infrastructure, provide support and maintenance.

Our Clients Think Highly of the Cooperation
ScienceSoft is the name we would recommend to anyone seeking a committed custom application development company. Our relationships covered multiple areas such as software development of server-based systems with desktop and mobile apps, software testing, software consulting and integration. We are especially impressed with the high quality of the deliverables.
ScienceSoft has worked with us to develop a library application that lets customers easily access their digital libraries on Windows, macOS, iOS, and Android. We have continued iterating on that application and adding new features over several years. ScienceSoft's developers produce good code, they are quick to respond, detail-oriented, and a very good value for our money.
ScienceSoft brought to the table substantial expertise in iOS and Android application development and a customer-centered approach to the application design.
They proved to be a reliable and agile technology partner. We appreciate their professional attitude to security.

What You Need to Know about Our Agile Development Process
|
|
We generally need 3–5 weeks to establish an efficient CI/CD process (for a mid-sized project with several microservices, an API layer and a front end). |
|
|
Our developers deliver code in 2- or 3-week iterations. Safe minor releases happen continuously via automated CI/CD pipelines. |
|
|
We advocate for the balanced combination of automated and manual testing to achieve maximum software quality while supporting frequent releases and staying cost-effective. |
|
|
We often do trial implementations for a limited number of users to minimize possible downtimes in production and ensure high user satisfaction. Trial stages usually take up to 1–3 months. |
App Architecture Patterns We Design
Tiered architecture
Apps have the presentation, application, and data tiers to enable concurrent, quick development, enhanced security, and dependency-free scalability.
Reactive architecture
Message-driven apps with lightning-quick responsiveness to user interactions and stable availability regardless of network and load conditions.
Microservices architecture
Apps are split into units based on business functions to facilitate continuous deployment, ensure high performance, and automate load management.
Cloud-native architecture
Loosely coupled microservices simplify portability, provide the highest availability, and help leverage automated performance scaling and PaaS services.
We Use Advanced Techs in App Development
We can go beyond widely adopted techs, if your solution requires it. Click on the innovative tech you are interested in to learn more about our relevant competencies.
ScienceSoft’s Practices to Drive App Development Success
ScienceSoft’s app development teams ensure achieving project goals despite time and budget constraints and strive to maximize the app value via well-thought-out design.
Here’s a quick snapshot of our development and project management practices. Follow the links to explore the detailed descriptions of our success-driven approach to integral project aspects backed by samples from ScienceSoft’s recent engagements.
Project planning
Our business analysts translate the client’s business needs into spot-on app requirements and shape the project scope, leaving room for feasible changes. We assign the resources necessary to cover the mapped task scope, deliver accurate cost and time estimates, and suggest cost optimization options.
UX and UI design
ScienceSoft’s UX designers use tailored UX research methods for each project and follow ISO 9241 guidelines to create convenient user journeys and intuitive workflows. Our UI designers factor in the demographic and psychographic characteristics of target users to ensure the app style resonates with user values.
Development flow
Our teams use flexible modular architectures and easy-to-maintain techs to ensure the app’s scalability and smooth evolution. Our clients receive comprehensive app documentation and regular reports on development progress. We devise a tailored risk mitigation strategy to address emerging issues quickly.
Quality controls
Relying on a quality management system backed by ISO 9001, we define tailored sets of app quality and project health metrics and enforce KPI-based quality controls at each SDLC stage. Our teams perform code reviews and functional, performance, security, and usability testing to ensure the app works as intended.
At ScienceSoft, we are for reasonable IT investments only. First, we check whether our clients already have the required functionality in their enterprise systems. If they do, re-using a part of legacy enterprise systems is often more efficient and less risky than developing and implementing new software modules and integrating them seamlessly. In this case, we reverse engineer legacy systems, refactor the code, add new interfaces if needed.
App Development Cooperation - Q&A
How does ScienceSoft ensure progress transparency?
At the start of cooperation, we work with you to compile a set of project KPIs, for instance, Cycle Time, Lead Time, Deployment Frequency, Stakeholder Satisfaction. Along with providing you access to our logging tools where you can monitor these metrics, we send you regular progress reports.
How long does it take to develop an app?
Development time depends on the scope of the application and can take up to 18 months. To accelerate time to market, we recommend our clients to start with a Minimum Viable Product that can be delivered in 2-4 months and enhanced iteratively onwards.
What pricing options do you offer?
- Fixed price – best for small app projects with fixed requirements.
- T&M – best for medium/large-scale app projects with a priority on flexibility.
- T&M with a cap – best for medium/large-scale app projects with a priority on cost risk reduction.
Is it worth going for custom app development?
It is if you have a specific set of requirements and want your app to be tailored to the processes of your organization or the needs of a specific user group, as opposed to mass-produced products. With ScienceSoft’s custom app development services, you get a one-of-a-kind app that guarantees:
- Minimized cost of app integrations.
- Cost-effective and quick app scalability.
- Best cost of ownership.
