This has been suggested several times before and so far it always came down to "make an app", nothing more. I'm not really well-versed in the whole process of making apps, but I know it's not that simple. It's not something that drops out of the sky when you need it. So instead of just saying "make an app", actually provide some technical support/ideas of how to make it. If you yourself have no idea about how to do it, you really shouldn't be suggesting this as you do not know whether this is even a viable idea.
