Android App - While You Where Gone

I have a VERY small budget for this project! I am looking for the following Android app! It's a "While Your Were Gone" app! Basically the concept is as follows.... Once your phones goes to standby, or has not been used for a period of time (night), the app will collect data from a few core places: unread emails missed phone calls missed text messges facebook messages battery status change (battery strength increase or decrease since) The app shall auto load once the user unlocks their phone from standby....the app shall show the above to the phone user to display what has taken place since the user last used their android phone. We will likely add more items to this in the future, so more money maybe available in the future.
