Vytvořit aplikaci pro iPhone

Hi, I am looking for an app that would automatically track and record all calls (in and out). So that I can see who called me and when. And all the phonecall recorded in it's own folder (date + name/number) on the given device. And if possible to add the function of answering machine as well. - the app should be able to sync with icloud (od dropbox, etc) and to keep on the phone only last month (or pre-defined size), while the rest online (sync performed only via Wi-Fi - not GSM) - the folder for the online service (iCloud, dropbox, etc) should be customized (so that I can use different folders for different iOS devices) I expect to receive IPA version that I can use on my iPhone/iPad without jailbreaking the system and to be compatible with current iOS. I expect functionality over design (can be raw graphic - for as long as it performs its tasks) if you can provide, let me know - aproximate delivery time and price
