I'm about to write an endgame table base app on various smartphone platfroms; Android / Iphone & Windows 7 phone.
I don't think there is one out there already (unless bundled with a chess program?), regardless I wanted to write this for my own learning experience on various smartphone platforms as I have a passion for chess but also it seems at outset a useful and relatively straightforward app to write. I'll probably start with Windows 7 phone that being more native to my experience. The app will be free.
Does anybody have any input/suggestions on matters such as;
- legality of using existing 'free' web services?
- legality of writing my own webservice based on the nalimov tablebases?
- what sort of features would the public wish for?
