Modernizing New York City’s food pantry system



Some of our clients are looking to create and launch a brand alongside a new iPhone application; others have an existing platform that needs to be redesigned and updated based on user needs and new iOS technology. Whatever your needs or industry, Big Human’s iOS development services have the capabilities to match.

Why Big Human for your iOS app development services?

We create iOS applications that are original, functional, and beautiful. Our application experiences include a diverse spectrum of clients, ranging from a startup founder testing an idea to established enterprise clients looking for a system upgrade. Our brilliant team of engineers has both front-end and back-end expertise, allowing us to serve each and every need of the clients we partner with.

iPhone App Development Case Study

Big Human has helped maintain Plentiful since we first built the app and administrative dashboard in 2016, fixing bugs and adding new functionalities ad hoc. To help Plentiful manage its records, we built a centralized database that acts as a content management system. More recently, we restructured Plentiful’s architecture with a modernized tech stack that can accommodate new features. Our engineers integrated a cloud-based, backend system that allows Plentiful to streamline deployments and efficiently handle codebases, which can be reconfigured depending on clients’ needs. Plentiful also lets users find local food pantries on a map, so we’re upgrading the search functionality to be faster and more powerful.

User Research Strategy

Developing an understanding of a client’s users and their needs is essential to building successful App Store applications. We utilize various methods of user research, data analysis, and competitive audits to assess the necessary user-first features and functionalities.

UX/UI Design

Tailoring a product to unique user journeys helps us create iOS applications that stand out. We’re exceptionally careful about considering how users interact with the application, from the first click through every design update. Our design process enables us to create seamless, easy-to-use applications.

Cross-Platform App Development

In the current technology age, we know it’s important for users to choose where and how to access their favorite applications. Because users aren’t tied to a single device, we have design and development capabilities across desktop, mobile, and tablet, as well as iOS apps, and Android apps.

QB & A/B Testing

We pride ourselves on being solutions-oriented collaborators. When it comes to finalizing an iPhone project, we don’t stop our work until every pixel is functional and in its final place. Once our applications have been designed, developed, and launched, we work to provide QA and A/B test any features that need to be ironed out to reach perfection.
