200+ BUSINESSES
Mobile apps are usually built to make a business process easier or to solve a business problem. We build apps that quickly improve sales, help employees follow the corporate plan, transform business operations and tackle real challenges.
A SWOT analysis lets us see your business model from your perspective, so we can propose a mobile app that precisely matches your product vision and business goals.
We visualise your app long before writing a line of code. You can change anything early, which saves significant cost on rework, and the team knows exactly what to build.
Based on discovery, design, budget and timeline, we help you choose native iOS and Android or cross-platform, and show where trimming the feature set can cut costs.
With a clear picture of your needs, technology, budget and timeline, we build quickly and aim for a flawless first impression. Building on earlier phases is how we reduce project risk.
Our QA team helps developers fix issues and optimise the front end and back end, working through 400 to 1,270 predefined test touchpoints.
Our DevOps team advises on deployment options that balance efficiency and performance, with usage, access, security and scale guiding every decision.

Then our free one-day workshop is an excellent opportunity. The apps you use every day started as ideas nurtured into an MVP by companies like O2SOFT.
What technology mix won't break my MVP budget? Do I need all these features? What does my audience really want, and what are my competitors doing? This one-day session is designed to answer these questions and more.

OnPremThey truly went above and beyond everything that we asked of them. In many ways it felt like they had become members of the team as they worked with us through a rigorous testing process to ensure that the app worked seamlessly.
I cannot recommend O2SOFT enough. They have been fantastic to work with, reliable and very knowledgeable about the whole app building and submission process.
A job well done. They are true professionals, quick to understand what is needed, think ahead, ask the right questions, respond quickly, and will do what it takes to ensure client satisfaction.
A great team to work with. Very flexible and understanding. They always made themselves available and provided great ideas in solving the many problems we encountered during the course of the project. Highly recommended!
Whether you are starting from an idea or rescuing something already in flight, the first conversation is free and useful either way.
