Working with you was great! I found the experience professional and refreshing, you were a lot more hands on and available than previous developers I had used. You made me feel like you really cared about my project. Your approach was professional and attentive.

Gareth Chapple

I’ve been working with Stephen and the team at GEM Custom Apps since 2013. GEM has delivered results on a number of projects, and I’m very happy with their services, and continued after sales service and support. I would definitely recommend them, 10 out of 10.
