I often forget writing down the time when arriving at a customer's home, or leaving it, so that SMS and calls that were sent or received just after/before are a great help to know how much time I spent with the client.
I'm looking for a solution that would let me see the full history (calls+SMS) on a single view. My phone is a Nokia Lumia 925 running Windows 8.1.
I'm looking preferably for either a native feature I didn't know about, or a computer software (preferably for Windows) to which I could transfer the history.
I would like avoiding third-party apps, in order to not jeopardize the security and the privacy of my phone. You can cite them for completeness, but please clearly mention them as phone apps.
