Ann: SleepCheck App for iPhone Now Available on the App Store, page-258

So while we are all talking about Sleepcheck others on this forum as well as TK have mentioned multi income streams.So I have been reading up on advert rates for apps and found out that a premium is paid in some cases for iPhone over android (income ).

So per download of the app could generate the the following income.
...cost of download ( once off )
...advertising, lots of option here
...data connected income ( ongoing gift )
...3 rd party referrals which could generate various rates for each type of enquire
searching /actual enquires/purchasing of 3 rd party products .

So my point here is that for every $5 download we generate long term we make another $. XYZ ( 5,10,20 ).
Happy for any experts who know how this side of business works.

dyor if it make you happy as I am not a expert , ask my wife.
