Mate in 3 chess puzzles free?

Does anyone knows where to download mate in 3 ONLY ! chess puzzles for free on android.

Pdf files fine too.

It seems that it's very difficult to find mate in 3 puzzles, it's easy to find mate in 1 and 2 , but almost impossible to find mate in 3 puzzles for some reason

Link is useless, I asked about the source, where I can DOWNLOAD it on my android

I've got an older app on my tablet that has about a thousand mate in 3's. Same for 1,2,4,5 and endgame puzzles. It's one of those apps that you have to tap twice to move the piece. No drag and drop. But I like it and use it all the time. It's called Chess by Bluesky studios. I couldn't find it on google play for some reason which is weird because that's where I got it. I found it here though.

I appreciate your time and link given, but it's a bit doggy for me mate. Asking to many things it shouldn't be asking that includes identity etc....

That sucks, ESP-918. It's a good little app. Very strange that It's not on google play anymore. That link I gave came up when I googled chess - bluesky studios. I didn't have to enter anything when I got it from google play.  I know you said for android but I have the same app on my iphone if you ever get an apple device.
