With the iPad I finally got my wish for a digital drawing tablet I could take out and sketch with. I've experimented with a lot of different apps over the years. In the early days I loved Adobe's 'Ideas' app - which had the bonus of being vector based. These days I mostly settle for 'Procreate'. I love the uncluttered interface, rock solid stability and the ability to export a time-lapse sequence of the process. This has proved very popular with clients looking to add interest to their Instagram pages.
