Red C started out building advanced enterprise web systems in 2002. We then relaunched as a dedicated mobile agency in 2007 – with a specialism for developing multi-platform apps with enterprise-level backend systems. We have continually refined our processes since, kept up with the latest innovations and pushed the boundaries of technical possibility.

Red C's UK-based developers are among the best in the business. Our development team is always available in-person or via phone/online within UK business hours (and out-of-office hours where required), report back regularly and will go the extra mile to ensure every project is completed to the highest-possible standard. They will also work on site with clients if preferred.

Thanks to our huge in-house code library and efficient processes, we are able to provide excellent value for money. We are proud of our reputation for delivering high-quality apps at affordable rates.

The best possible design and an engaging user experience is crucial to the development of a successful app. The industry design bar is set very high these days and it is important to stand out from the competition when appealing to app-savvy business users and millennials.

Transparent and honest communications between clients and our team is at the core of everything that we do at Red C. We partner with our clients to ensure that the best possible outcome is achieved so that their apps are a complete success – we will  do everything that we can to ensure it.

We are passionate about implementing our clients' ideas. We guide each client through every step of the process with regular meetings and using online project management tools that allow them to see their project's progress at any given time. Our total commitment to client satisfaction remains constant; we do whatever it takes to deliver projects on time and on budget.


Mobile app for parents

Young Planet approached Red C to develop iOS and Android apps that enable parents to pass on unwanted children’s items to new homes – where the items can be enjoyed again and have a second life cycle.

Prepaid card fintech app

Red C was commissioned by the Blackhawk Network to build iOS and Android apps for its new proposition, Yonda.

Yonda is a prepaid card that encourages users to set a savings goal and then rewards them via loyalty cashback each month.

Yonda is on track to become a market-leading, consumer-driven, prepaid purchasing solution.
