I googled “submission planner” and came up with this website – Writer’s Planner. It’s a free online planner for writers (which is stating the obvious, I know) where you can track your queries and submissions.
I set up an account and entered Cat’s Eyes and three of my short stories to see how easy the site is to navigate. At first, I got mighty lost, but once I got used to where things are placed it’s not that difficult. Although the owner says you can track queries and submissions, there isn’t a way (that I could find) to distinguish between the two, which is a shame. Querying and submitting are quite different, in my opinion, and should be separate from each other. Also, I would have liked to see some additional options for completed manuscripts that might need editing or further rewrites, before they get to the query/submission stage. My manuscripts that fit into this category have not been added to the site, which means my list is not complete. What a shame.
I haven’t used the site long enough to really recommend it, but if you are looking for a service like this, it costs nothing to try.
