Hi, have you thought about the details of your requirements, in terms of how the layout of the windows should be, what variables do you want to store etc, I have some application that I have written, I can create some short videos of how they work, to help you with the conceptual process.
And of course we can develop anything that you want, we have applications in the Microsoft Store, Xbox Store, Google Play Store and Apple App Store
Thanks,
Felice
