uApp Explorer was down with an error and I brought it back up again. But it should probably be shutdown and direct everyone to either the OpenStore for click apps or the Snap store for snaps as it is a bit redundant now. To clear up some confusion, uApp Explorer doesn't host any of the clicks/snaps it provides. It showed apps from the Canonical app store back in the day (which is why you can find older apps that doen't exist on the OpenStore), the snap store, and eventually the OpenStore. I also want to note that while I'm now the main developer for the OpenStore it was all started by Michael Zanetti before UBports took over the development of Ubuntu Touch (so a huge thanks to him for getting it started!).
