I am a "self-teaching" desktop publisher. Several years ago, I downloaded iStudio Publisher and have been extremely pleased with it ever since. The software is very user friendly and intuitive, and it allows me to do everything I need to do with a very small learning curve. Although it is not a drawing program, I am still able to create small icons and graphics easily with professional looking results.
The preparation of multipage instructional lessons consisting of photographs, graphic representations of equipment in industry, and text can be a challenge. However, iStudio Publisher has allowed me to learn as I go and still prepare very professional layouts on various sizes of pages. In addition, the recently added option of "Export Document as a Booklet" is a fabulous feature for publishing booklets for viewing on iPads and computer screens without numerous added steps. The clients have been very impressed with the end products.
Any review would be lacking without reference to the customer support provided by the developer. Again, as a novice to desktop publishing, I have had numerous questions, especially at the beginning of my learning. The customer support at iStudio is beyond great! They are prompt, thorough, and go the extra mile to offer solutions for any question asked, they respond within hours, (not days!), and are so patient, informative, and friendly. They also listen to suggestions and requests for future updates and consider those ideas for development as possible.
All in all, I could not be happier with a software/app or the people behind the scenes!!!
