Rapptr Labs

Rapptr is a product studio that designs and builds mobile and web applications for startups and established brands. Its teams combine designers, product leads and senior engineers, with QA specialists who sign off each release. Clients own all the code that the studio produces.

The studio uses AI tooling in its own process. The tools read a client's existing code, backlog, designs and user reviews so that the team understands the product before it starts work. Projects begin with a conversation and a scoped estimate.

Published work covers native iOS and Android development, Flutter and cross-platform builds, and web platforms with content management systems. Case studies include a home search app for Realtor.com, an interactive learning app for Imprint, a guided meditation app for The Tapping Solution and a fitness app for Alter. Other named clients include Nike, B&H Photo and WeightWatchers.

The firm is based in the New York metropolitan area, with its main office in Jersey City, New Jersey. It covers the full product lifecycle from early concept and UX design to launch, analytics, optimisation and ongoing support.
