Any feedback welcome and very desired!

Are you using HTTPS for the requests? (It didn't say on the website). Leaking the API key seems quite a risk if that's is all you need to query the database of a wordpress installation.

Do you query the database of the installed wordpress or are the stats stored centrally?

I query central database. I have not found before that wordpress.com api support https - but now I see it does (there are no docs for stats). In next version WP Stats will query over https (now it is http).

BTW even if someone would get your api key they can do nothing more than check your traffic.

Whats with the spammy ads on the blog?

Do you get enough traffic for that to make money? I closed the site as soon as I saw that.

Edit: I understand it's adsense, I was questioning why put them on a blog, not what links the ad contains.

I think he have not much control over what adsense display to you...

Do you mean adsense ads...?

..yes, why put adsense on a personal blog? Surely you can't make much money off of it unless you have tons of traffic and it hurts the user experience of the site.

I don't use adblock so I have to sift through ads designed to look like your content to find what your trying to write. No thanks.

I am independent developer and do not go to full time job - so every cent is important to me. Sorry if it is a problem that I make free apps and need to make some money for a living...

I also happen to have a personal blog with adsense, with even very low traffic it pays the hosting and the incredibly abusive Net fee.

Congratulations if you're rich, sadly most of us don't.

Cool. Haven't tried the app yet, but I was looking for something like this. Browser interface is really cumbersome, so any alternative interface would be an improvement.

Thanks! Hope you will try and like it :) I am already addicted to my own app as i check stats a few times a day ;)

Congratulations! I have serious respect for anyone who dives into a new environment like that and sticks to it. Did you know Java already or learned it "on the fly" too?

I knew very very basics. I have tried a few times to learn it but never had a real reason too. But now I really wanted to go into mobile software development and had to learn it better.
