The answer, like many copyright questions, is complicated.
First, the images of the software interface is almost certainly copyrighted. As a result, the exclusive rights to reproduce images of the applicatoin lie with the copyright holder (i.e., the creator of the software.
However, as another answer has suggested, the use of a single screenshot of an application should almost certainly qualify as Fair Use under US copyright law or something similar and analogous under other systems. In other words, it's a small and relative inconsequential reproduction that you can do without having to ask for permission.
However, fair use is notoriously tricky and subjective. there is a multi-prong balancing test at the heart of fair use that is complicated and that makes it hard to know for sure whether a use if fair or not. As a result, many journals are risk averse and will systematically block many types of "probably fair" uses. I've had difficult conversations with production staff members and editors about the use of software screenshots before.
I would say go ahead and try to have the conversation with your journal editor or production staff. The worst thing they can do is ask you to take it out. This, of course, is what you would do preemptively now if you choose not to include it in the first place.
