Hi,
I can build audio recording app like this.
For more than seven years I work as an iOS developer freelancer. During that time, my focus is strict to native iOS front-end applications. I did work with my clients from all around the world: USA, Australia, Deutschland, Italy, France, United Arab Emirates, Greek, China and many others. They rated me with the best scores in over 75 projects and more than a thousand billed hours combined.
Best,
Vedran
