I had asked about such an app in this forum about 3 years back:

Diyan did it finally..

Was happy to help out with testing..

Very good idea and it will be much better when solving becomes possible. Cell phones are faster now than computers were a few years ago and the future is open for further progress.
There is one thought I had when I read the news, which is unrelated to this nice effort, but it is something we may need to worry in the future: Cheating in quick solving competitions. Cheating has become a serious problem in tournament chess, probably the most serious threat the game ever faced, and we may want to start thinking about anti-cheating measures in solving events. Problemists are respectable people, but so are chess players in general, and we have seen some cheating in that field.

I did think it would be difficult to fit a solving app into a smartphone.. was satisfied with just a position creating, editing, saving and retrieving tool..

But such is the pace of progress in the smartphone field that i did a re-think..
Kostas is right.. Today's smartphones pack more processing power, memory and screen resolution than the PCs of some years back.. i think i tried an early version of popeye on what was called a PC/XT back in '89..:-P

Both android and iOS have a linux/unix back end.. so theoretically it should be possible to compile popeye to run on both.. If any of the popeye developers are reading this, then maybe they can comment.. and more importantly, attempt a port..! :-)

Regarding cheating in solving competitions.. is there really so much at stake to do such a thing..? and as far as i can make out from photos of such events, the participants seem to be closely monitored..

But this may well be true in the informal solving competitions of many magazines.. (do they still exist..? :-P) Here, a solver may possibly be popeye/alybadix/winchloe/gustav in disguise..! :-)

Popeye is distributed under the GNU General Public License. Re-distributing it via the App Store could be legally tricky (and may be against the spirit of Popeye?)

Now we started working on 2nd updated and improved version with more useful functions (will present them later). Of course if the app have solving option this will be great to all composers, but this should be discussed.

I saw some opinions against the price of the app, so I should explain that we not sell it because want to become rich. All of us know that we are very small community so nobody can not make profit with this. The only reason to sell the full version is to collect some money and to pay with them to the programmers for continued working on more improved versions of the app. I think that if we have useful chess composing tool for smartphones will be good for all of us. But to create it is too expensive to a single person like me, so that's why I decide to put it with price. Actually I think that 10 Eur is not so expensive (this is cost of one normal chess set, or book).

I have seen several linux utilities as paid apps in google play..
e.g: busybox, vnc server..
the authors just add an android front end..
so somebody can try an Apwin like project..

Did you ask Olaf Jenkner to participate? He has one of the best solving engines. I would pay even 20 bucks to have Gustav in my pocket ;)

I've never owned any sort of smartphone and probably never will, but I suppose something that could serve as a shell to multiple engines would be great. Isn't there some way the program could access a running engine on something like a Wi-Fi connected PC?

Does it work on tablets?

No, it runs only at Windows for personal computers.
Linux users can use Wine to run Gustav.

some confusion here..!

If Mr Turner's asking about the smartphone app (which seems likely), then the answer is yes.. but it may appear a bit oversized..

Since there are windows tablets too, then Gustav should run on them at least..

On Linux, a better alternative to Wine is Virtualbox..

Only Android at the moment, according to Kobulchess. Any plans to port to iPhone?

The app is working on Android OS smarphones. Now we preparing new version with some improvements and more options (better view of buttons, diagram, option for saving and presenting solutions with active pieces on the board etc.). After that we will think about iOS.

About the solving option - actually it is possible the app to be prepared as Popeye shell and to send generated Input files and receive the solution via internet, but we do not planing to make it for now (because of several reasons).

So the app is independent and the main idea of it is to be used as an electronic chess set with many fairy pieces and functions as database, sharing and presentation of problems on smartphones.
