I have occasionally thought that someone should make a "death app". An app that would have all kind of stuff you should do because you die one day. Not just a check list (which would be a good start), but you actually would be able to write your will, make organ donation contracts (or whatever they are), store information for the chosen ones after you die etc. Could also remind you that it's so long since you donated blood that might be time again.

Feel free to steal this startup idea. I'm afraid there might be some hurdles marketing this - and also localization can be a challenge.
