What we offer

About us

Based near Liverpool Street in London, we are a small software company that offers companies of all sizes high quality mobile app development and responsive, mobile friendly website design services. We develop for iPhone, iPad, Android and Windows Phone. We also build websites using Microsoft .NET technologies including the popular Umbraco content management system.

Mobile app development

We provide business grade mobile apps for iPhone, iPad, Android and Windows Phone that will help build your brand, engage your users and provide a return on investment. We have a strong niche in serving customers in the accountancy and legal sector including RSM, Kreston International, MSI Global Alliance and Multilaw.

Responsive web design

We can provide one website that will display optimally on all screen sizes, whether a small iPhone screen or a huge iMAC screen. Responsive website design ensures you only ever have to update one website. Let us talk you through how you can ensure your site is "mobile ready".

Recent work

We developed a directory style app for international accounting group RSM for iPhone/iPad, Android and BlackBerry. The app allows RSM's members to connect while they are on the road. Members can view profiles, office locations and email and phone each other. The app updates seamlessly via the Appergy Cloud service.

Apps for memberships

We are the market leader in providing mobile solutions to membership organisations that need to publish their news, meetings and directories to their members' smartphones. Our apps are secure, work on all smartphones, and update dynamically via the web. Innovative companies such as RSM and Kreston International use the Appergy product to extend their services successfully to the mobile channel.
