When we launched Tower for Mac a few years back, we didn’t have any plans for a Windows version. However as we received more and more requests from our users, we finally decided to commit to it. As we’re bootstrapped and a small team, it took us longer than expected. But now we have a 100% native app and even so it’s still in beta, we are really happy with the result. It’s also great to see that other Mac apps are making the move to Windows as well. This might also have to do with the new leadership at Microsoft and their efforts in supporting developers. So far it's been really great working with them and they've been very supportive.
