I'm surprised no one has posted in this forum about this app--which finally became available. I'm a long long time user of Photo apps on Windows and then on Mac OS but I've come to love the Ipad for use with photography. I've waited for this app because I like using the Pencil on the 12.9 Ipad Pro in various photo apps or Astropad in conjunction with my Macbook/PS or LR (I have used large Wacom graphic apps for years). Affinity took me a bit to adjust to its ways of using tools and menus but I really do like it, am working on a workflow (to eventually upload to external drives via Macbook). Its a very well done photo app and if I work out other things besides the processing will likely drop my Adobe CC for PHotoshop and Lightroom. Its well worth the price (not sure if its still $20 on sale or the full $30 now) if you do process your own photos from RAW or jpeg. They have a well done group of tutes for the Ipad version and once you feel comfortable with the tools you can use the very large group of tutes for the Mac version and relate them to the Ipad tools. Printing from the app is problematical I understand--I don't print too much any more and Lightroom had an outstanding method for printing with my big Epson but if you do, expect to export in order to print.
