FREE apps daily, for iPad & iPhone.......... and Android too

[#1]

These are a couple of sites, I visit daily, RSS etc, with daily free apps for iPad, iPhone & Android.
I know Android is not Mac, but I do backup my Androids to my iMac !

Amazon App store also offers a 'Free App of the day' (for Android - I don't know about iThings):

I didn't include that because in the UK, at the moment, we are not allowed to use the US app store, as such.
There is a direct download link, but it can only be viewed with an Android device, not my iMac, so again, I did not include it.

Download the Amazon Appstore
   * From your Android phone or tablet, visit: http://www.amazon.co.uk/appstore-web
where you can download the .apk to your computer , and manually copy to your Android device, in the UK, if you need to.

I haven't tried this yet, so cannot confirm there are any FREE UK apps available.
Now downloading to my UK Android, it does state there is a FREE app every day !

Never had the "unable" message, mind you I haven't gotten that much from Amazon, I get more free ebooks than anything else from them.

Sorry, Blame 'your friend' Google for finding the USA one rather than the UK one. 
I've had quite a few free apps from the Amazon (UK) App Store.
