There are some Windows 10 universal apps written by third party developers that work with Splitwise. Here are two we’re aware of:
We can’t endorse these apps specifically, but you may find them useful.j22222 commented
Slack currently has two separate apps for desktop and mobile: an antiquated Win32 version for desktop PCs and an entirely separate Windows Phone app. At this point however, it would be easier for Slack to drop the desktop-only app and update their Windows Phone app to a universal Windows 10 app. That way, their W10 app will run identically on both PC and mobile, rather than having to manage two separate apps as they currently do. In fact, this is their plan: a friend who works for Slack tells me their Windows 10 mobile app can easily run on PCs, at this point they are just finalizing the adaptive UX (what allows their universal app to scale appropriately to screens of different sizes and shapes) before they publish to the Windows Store.
As for Electron, that is NOT what companies use to make universal apps. Electron produces legacy desktop software, not universal apps that scale across desktop, mobile phones and tablets, Xbox, Hololens, Surface Hub, etc. For a truly universal app, I recommend Visual Studio 2015 or Xamarin, or simply using Microsoft's new bridge tools like Project Islandwood which we have seen in some cases can port an iOS app to Windows 10 in less than 5 minutes.j22222 supported this idea ·
