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:
Well I use Flurry to track installs and session. But you will have to add the flurry to your project.
And We als use AppFigures to track real downloads, but as you stated you can only retrieve so far back as Apple allows it. AppFigures will also require you to give them your ItunnesConnect account details.
The iTunes connect app has other selection methods, try it. https://itunes.apple.com/us/app/itunes-connect-mobile/id376771144?mt=8
Apple just updated https://itunesconnect.apple.com site you can adjust the date range in the middle of screen (using the slider) or by adjusting the dates on top left corner after navigating to sale and trends screen to see how many downloads you have had.
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.
Just for your information there is another services called mopapp, it supports several platform.
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.
That, seems like a very good idea!
Why not hire a sales guy to count the numbers for you? But in all seriousness, I'd go with the scraping option. I believe that's the only viable solution for your problem until Apple comes up with an API.
