- My Quick Shopper app is a fairly simple app for creating a current shopping list from reusable items I designed based on my own shopping list habits. It is currently optimized for 7-inch tablets.
- It became available on the Barnes and Noble Nook app market on October 28th at a price of $1. On the Nook app market, the search term "shopping" returns 4 results for apps focused on shopping lists or the act of shopping.
- It became available on the Amazon App Store around November 26th, also at a price of $1. In the Amazon App Store, the search term "shopping" returns over 400 results.
- If Quick Shopper was highlighted or advertised in some way on either market, I am unaware of it.
The sales numbers for the first 30 days in each app market:
- Amazon - 4 sales
- Nook - 478 sales
- 478 > 4 (by a lot).
I know of at least one other developer who sees higher sales of his same app in the Nook market over the Amazon market.
The most likely cause of the vast difference in sales is that my app has very little competition in the Nook market, while in the Amazon App Store it's simply lost in a sea of similar apps, some of which are free.
But since I'm not the only app developer who's seeing more success in the Nook market than they are in the Amazon App Store, there may be other factors at work. The Nook app market exists solely to provide apps for the Nook Color and the newer Nook Tablet: anyone using that market knows that any app they see is (supposedly) designed for use on those tablets. The Amazon App Store on the other hand caters to Android phones and standard Android tablets in addition to Amazon's own Kindle Fire, so perhaps the phone-targeted apps get more of the attention and the ratings because of the wider install base.
It may also have something to do with the buying habits of the different audiences. I attended a web-based presentation given by a Nook evangelist who said that their studies showed Nook owners were far more willing to pay for apps than the average Android user (or something to that effect; I forget exactly what the slide said). The sales numbers I've seen would seem to support that claim.
Of course, this is just my experience. If other developers are seeing similar results or perhaps even the opposite, I'd like to hear about it.
