For your use case, I think the most flexible tool is found in Systems Manager > Monitor > Software. you can focus in on a particular app, from the list, simply by clicking on it. You may well also find it useful to download the software inventory for all your managed devices, using 'Download as CSV', top right. Judicious use of filter and sort in Excel should allow to focus in on the particular application you're interested in. Systems manager > Manage > Apps may also be of interest, depending whether the app in question is SM-managed or not.
