programmer 9-5 day job appstore 30 days sales report

Okay, so i will share some data for the user who follow my developer blog

the programmer 9-5 day job was release on the appstore on 23 october, and below is the sale report after 30 days

total unit sold is 91, for which majority of the sale occur in the first 3 days, then slowly it goes to zero, once it reach zero it will stay at zero forever, with 0 chance of ever been seen by anyone ever

total time taken to build the games = 25 days, total revenue made is $61 so it is not very good but at least not the worst of zero

why there is traffic at first 3 days ???? since the appstore already remove the "new release" section???? well the traffic is coming from the old device, old iphone and old ipad with old IOS version, meaning the majority of 80% new device will never see my app ever, and the number of old device will only decrease overtime making it is harder and harder for my app to be seen
