An app that automatically records and saves your calls to the cloud from your phone.

Something like Google voice recorder for calls, but for the cloud (like dropbox, mega, etc.). Maybe if you want an extra layer of security it could also encrypt the voice recordings before sending them to the cloud. An example of this would be from _The Social Network_ movie, where Mark Zuckerberg said that he "would always always record calls" as if he was some kind of cold-blooded kingpin. If you went through something traumatising, like a car accident or a threatening phone call, would you want to pay for a subscription for each individual "phone company" like AT\&T, T-Mobile, or any others for some kind of security blanket in case things go sour? Well this eliminates that.
