Thanks to Johan Hedman, Certified FileMaker Developer på Atatiki AB for pointing this :
Have you ever thought about what is the difference between FileMaker Go and FileMaker Pro.
Yes, the obvious is that one is installed on a computer and the other on a device.
But besides that, there are quite a few things that look and work differently.
Your solution could of course work on both Mac, PC and on a device, but the basic thing is, in what way do your users need to access your solution.
