Currently there 2 versions of MSP. one for Android, one for Windows. The 2 apps can 'talk' to each other, eg., ttrade files  or share/trade backups. The Companion app [the Windows component is for interactions [uploading/downloading] between your laptop and  your Android device. It is not needed in a Windows only environment.
I have both versions, but use my Android version almost all the time, essentially exactly as you wish to do. I got the 2in1 because my old computer failed and my tablet is pretty old, kind of a 2 birds at once decision.

Thanks for your comments, very helpful. I'll continue checking out the Windows version. If I need to buy two versions, the price point brings into play a few other options which I'll have a look at as well.
