Diffco specializes in native
and cross-platform mobile application development for iOS and Android

Our mobile development team is fluent in the mobile guidelines, UI standards, and best practices of Apple and Google. With our extensive experience, we see to every detail to make your apps powerful, user-friendly, and successful.

Project approaches


Our team can fully develop and maintain your iOS and Android mobile applications, or we can collaborate with your project team in a joint development effort.

Mobile + backend

When you need to develop a backend solution to support your mobile app, our backend engineering team is ready to help.

Web version

If you need a web application along with your mobile app, our front-end team will help you to achieve your goals.

Admin panel

We design and develop easy-to-use admin panels for mobile and web apps, using popular UI solutions that are reliable and easy to support and extend.

Project Stages and Flow

Based on your current project stage, we will propose the most effective plan to achieve your objectives—within your timeframe and budget.

Our typical project flow includes the following stages.


Discovery stage

To efficiently plan and run your project, we start with discovery. In this four-step stage, we collaborate with you to align functionality, prioritize business goals, coordinate strategy, and prototype future products. During discovery, we also define your deadlines and budget.


Design stage

After developing a prototype wireframe, our design team starts to create your application style (the app’s “look and feel”). In this stage, we provide you with a full set of UI screens to use for further development.


Development stage

Product development typically evolves across multiple releases, including a minimum viable product (MVP) for the earliest possible release. To speed the process, we use Agile development with short sprints, and we run the development stage in parallel with design wireframes, documentation, and mockups.


Ongoing development, support, and maintenance stage

After releasing the MVP, our team performs new sprints to speed new releases with additional functionality. And we support and maintain the latest version of the launched app.

Discovery Stage

In Diffco’s project flow, the critical discovery stage includes four segments.


PRD (Documentation)

The product requirements document is a comprehensive specification and plan for product creation. The PRD specifies your business needs, describes the associated technical requirements, and helps plan all stages of your product development.



A wireframe is a visual prototype of your product that shows all application screens and user flows. We can develop a dynamic prototype that you can test with project teams and alpha users., and demonstrate to your investors and business partners.



If you need deeper technical research and analysis, more extensive testing of an existing solution, or ideation of a new solution, we will allocate the necessary resources for research and development.


Product strategy

If you are in the early stages of development, we can help you choose the best ideas to fulfill your product vision. Our team will brainstorm with you on functionality, define the solution scope and logic, develop a wireframe, plan the next stages of development, and schedule releases. Our process ensures that we mutually understand and agree on your product goals.

Q: Already have a PRD, wireframe, or initial design?

A: That’s great. Our design and engineering team will analyze your project to determine the remaining scope of work and suggest a vision for the next stages of development.

Time & Materials

For outsourced software development, a time-and-materials (T&M) approach saves you money—and produces better results—than a fixed-price contract. That’s because the best software requires flexible thinking, tweaks to requirements, and shifts in scope. And because with fixed-price estimates, you always overpay for risk contingencies that you probably won’t need. Read our blog for a full analysis

Agile vs Waterfall

Agile software development involves a series of short sprints to ensure rapid, transparent progress toward your product goals. We apply this nimble, responsive approach to incorporate your feedback, adjust priorities as needed, and ensure your approval at every step. We use the Agile best practice because it is more flexible—and less risky—than the linear Waterfall development methodology.

UI/UX design, prototyping

Your user interface (UI) and user experience (UX) are keys to your success. Our UI development process is dynamic and iterative, based on prototypes, user feedback, and analytics that let us see your UI through your customers’ eyes. Our progressive UI development also saves you time and money, because it eliminates late, unexpected scope changes.

Automated QA and testing

Automated quality assurance and testing are best practices in software development. We implement QA automation solutions and testing tools because they yield significant advantages for our clients, including the highest product quality, lowest costs, and fastest releases.

Adherence to industry best practices and technology standards

Throughout our software development process, we emphasize clean architecture, design patterns, code readability, and documentation. We follow principles established by Google (e.g., style guides for Javascript, Typescript, Java, and Kotlin) and Apple (e.g., guides for Swift and Objective-C). We also adhere to the general engineering principles of KISS, DRY, and SOLID.

Compliance with security standards and policies

We follow industry best practices to meet each client’s security needs. We can help you comply with security standards and regulations such as SOC 2, PCI DSS, GDPR, and HIPAA. We also provide strict version control and automatic code and data backups to ensure product continuity and protect you against critical data loss.

Analytics and
product optimization

To add greater value to your business, we use analytics to refine your product and maximize your return on investment. We make data-driven decisions on UI/UX impact, content, and process flow. And we could help your marketing team maximize conversions, revenue, and profits. Our engineers integrate your goals and metrics to build conversion funnels, going far beyond simple tracking pixels.

Our whole-solution approach

The Diffco development team doesn’t just code product functions. We give you our expertise and experience to help your solution succeed. We suggest ideas, build dynamically and flexibly, see you through the initial launch, and help you envision and evolve the future for your business.

Application types


Launching your application is a critical task that requires careful, upfront planning. Many developers overlook crucial steps that can delay a launch. But launch support is one of Diffco’s core competencies and a vital value-added service.

Google Play/Apple App Store

We know how to organize and manage the entire launch process with Google and Apple. We help you prepare everything you need to publish your app, meet compliance requirements, set up the distribution infrastructure, and establish all necessary external accounts. We know how to get it right the first time, so you can focus on growing revenue instead of fixing launch issues.

CI/CD for deployment

Product development doesn’t end with launch. We apply the best practice of continuous integration and continuous delivery (CI/CD) to optimize your ongoing product releases, incorporating what we learn along the way. The CI/CD process reduces the risk of product downtime and lowers the cost of new releases.
