noGo is a cross-platform sgf viewer and editor. It is written in Python, and uses the Gomill suite of Go utilities to read SGFs and keep track of board logic. The GUI is built using the kivy graphical framework. noGo includes ~1100 games covering mostly Japanese title matches over the last few decades, from Andries Brouwer's public domain collection (http://homepages.cwi.nl/~aeb/go/games/index.html).
noGo is a work in progress, and any questions, bug reports, requests, suggestions or anything else are welcome! Please contact alexanderjohntaylor@gmail.com or submit an issue at https://github.com/inclement/noGo.
noGo is primarily intended for android, though the source here should work on any desktop with the necessary libraries available (mainly kivy). If building for android, the buildozer tool (https://github.com/kivy/buildozer) makes things very easy.
The app is mainly distributed on the Play store at https://play.google.com/store/apps/details?id=net.inclem.nogo . It may also be available in other app stores, let me know if there's one you'd like me to submit to.
noGo is distributed with the Gomill set of SGF utilities.
The APK form is also bundled with a full set of python libraries and the kivy gui framework.
