Count iOS App downloads

Question

Problem:
I\'m an app developer and my boss asked me how many times one of our iPhone apps was downloaded

What I tried so far:

Answer 1

Services like www.appannie.com: This might work, but I don't really want to give them the email and password of our developer account.

i use appAnnie, but i didn't gave them my "email and password of my developer account".

in ItunnesConnect apple site you can create a new account with JUST the privilege to see the reports of a single app, and nothing more

P.S. This may be very useful in case you want to give access to a client or a developer partner to a single app statistics, as you can create a new appAnnie user with access to just an app.
