I use the Submittable website every day. I’ve used it from both sides—as an editor and submitter—and it’s invaluable. But this app only has about 20% of the website’s functionality, and it seems to be in a holding pattern without new features in the works. The discover feature works great. But be warned, you can’t use the app to review submissions as an editor or to create new submissions as a writer. Seems pricey, given those limitations.
