What Quinn said, plus
Wondering if writing an app will make life easier in the long run, plus, some day I will need to pass the coordinating to someone else. It would be easier for them to learn an app versus all the steps in Excel.
It depends on the complexity of the app, but, by experience, reworking on a sophisticated Excel sheet written by someone else is really tricky and error prone.
So, if your application is a little bit sophisticated, Excel is not the way to go (IMHO). In addition, native app will let you add features that cannot be implemented in Excel.
An app appears well adapted and SwiftUI would probably make it pretty easy to develop.
Do I develop using Swift (and deal with finding future replacement with a Mac)
What is your concern with Mac ?
BTW, SwiftUI makes it easy to be cross platforms (Mac, iOS, iPadOS…)
Don't forget to close the thread once you have made your mind.
