Help to understand the Android App Market.

Hi,

I need some help to understand how the Android app market works.

I don't have an Android device but I have a blog where I write on different OS, iOS, Android, Windows and Symbian.

I talk about photography and videography only. And I'm interested in only those apps.

I need to understand few things if you can help me, please. So I can offer a better service to my readers.

1) Is there the in-app purchase on the most of the Android apps? When I see the apps on google play, I never see anything about other costs. How can I check if is there an in-app purchase for an app on the web only?

2) How do the redeem codes or promo codes work? Can I ask to a developer a promo code to give to my readers to test the app? What should I ask exactly?

3) Is there a Web App where I can check every day the apps that go free, on photography only?

Thank you very much, I hope you can help me to well understand this market.

 

Thank you for your answers. I've just bookmarked AppBrain.com for now and I'll check it better this weekend. And I'll start to check the permissions for eventually some in-app purchase.

How the promo codes work in any case? It can be a silly question but I prefer to ask to be sure. Do you insert a key directly from the telephone or do you do it from the desktop and sync on the telephone later?

 

oh! It sounds a bit complicated or am I wrong? So the promo code depends on the country or on the device type? Or it's just for the app type and version and if I get one from a developer, I can just give it to first that want to write the review for it?

Thanks for the welcome

 

ok, I understand that, thank you. It's easier if they pay the cost with paypal then! :O

Last question if you don't mind. Is google play the only market for the apps? Reading around, sometimes I ended up to Androidzoom or even another one that I don't remember, if I'm not wrong. But I haven't checked if all the apps are inside google play.

 

oh! The most of the time I end up talking about apps that show on google play market so I thought it was the only one or sort of. Thanks in any case.
