We couldn't be more pleased with our experience with TouchZen. They took over a bad situation left behind by our previous development team and have been able to continue to build new features while cleaning up the old project. We have been very pleased with their developers responsiveness as well as the project management. I would highly recommend working with them for any of your web or mobile app development needs.

Mobile App Development Review from Dr Asa Frey
They worked on our app and continue to work on it to this day. We originally had a bad experience with various developers and ended up with a bunch of code and no functioning app - touchzen took the code and audited it and made it work and it work great now. Can't complain - still going to work with them and I would recommend to anyone who wants it done right.
