Benjamin Mayo, writing for 9 to 5 Mac:
Via iGeneration, it seems that the Workflow app is in maintenance mode and unlikely to gain any new features in the foreseeable future. According to an email reply a user received from Workflow support, there are no ‘further updates planned’ for the automation app although they will continue to maintain its existing functionality — presumably with occasional bug fix releases.
I had unreasonably high hopes that Apple would continue to develop the Workflow app into something much more powerful than it is today. But unfortunately, that doesn’t appear to be the case. We shouldn’t expect anything more than bug fixes going forward.
I don’t think most Workflow users will turn to alternatives anytime soon, though. Primarily because there aren’t any other good options. Launch Center Pro and Pythonista immediately come to mind, but one of them is too underpowered while the other has a high barrier to entry.
The last remaining hope for iOS power users is that the team behind Workflow are currently working on a replacement, built from the ground up within Apple, that will ship before Workflow no longer functions. We won’t be seeing any new features until then, but as long as what we have now continues to work, I think it’ll turn out okay.
