If at exporting or saving the image the program won’t keep adding that ugly black background that ruin everything. I assure most users wants png transparent background !Developer Response
Thanks for taking the time to review our app. As you suggested, we have added the support for transparent background and made saving the image as PNG format as default. Please update to version 1.0.4. It'll take a few days for the update to be approved and shown on the store. Please let us know any issues or any features that you would like to us to add. Thanks again!
