What to develop?

[slooksterpsv]

I know how to make apps. I use C# every day. I've made some Xaml-based apps for Windows. I just don't know what others want or need. I don't even know what I want or need but I want to develop something... Any ideas?

Well I've heard of smart alarms that only turn off once you've walked a few feet with them. Maybe sth like that for the band? but instead of measuring distance you measure heartbeats? or solve an equation? Not sure if these apps can be made for the band, but just saying, could be handy?
