Call Reminder

I have an idea for an app. Being an Insurance Agent it is tough to keep track of random phone numbers that you call or call you. So my idea is that if a number calls you it brings up the last 5 or 10 texts, or calls that you have received or sent from them instead of the full screen trying to display their pictures. I really feel like if you could make an app like this it would be a huge hit with the professional communities.
