Empowering communities to combat worldwide deforestation

The Global Forest Watch initiative aims to combat deforestation by putting the power of location monitoring in the hands of rangers, communities and individuals passionate about protecting our forests. The app does exactly that, letting people track specific areas and send reports on evidence of deforestation.

Lush Lens App

A package-free store to reduce global plastic pollution

LUSH opened its first package-free cosmetics store in Milan in 2018. We used object recognition technology to develop a mobile app which replaced the need for packaging; simply point your phone at a product, and you'll see everything you need to know, from ingredients and price to origins and health benefits.

American Red Cross


Transforming the way America donates blood

To stop declining blood donations across the US, we collaborated with The American Red Cross to develop the world’s first blood tracking app. Blood Donor lets users manage their appointments, form teams, earn rewards, receive shortage alerts and even track their donations to the hospitals they’re used in.

Helping brands change the way the world works

Since our inception in 2009, while the App Store was still in its early life, we’ve used our mission to pioneer Tech for Good to create platforms that have a positive impact.

From our first project making vision testing software with Boots to being invited to the White House for our work with The American Red Cross, we’ve collaborated with changemaker brands in the fields of charity and nonprofit, disaster management, conservation, health, wellbeing and more.

Nowadays we’re a team of 30+ techies all passionate about making a difference with mobile apps, and our reach has grown from our base in Bournemouth to making an impact on communities in over 100 countries.
