BW-Go

BW-Go (Black & White Go) is a flexible, easy-to-use SGF editor to record, analyze, study and replay Go / Igo / Weiqi / Baduk games. A Gnu Go computer player is available as a separate download to play against Android.
Also, download the free BW-DGS plugin to play on the turn-based Dragon Go Server.

If you encounter any problems, please mail me. Any feedback is welcome, including suggestions for later versions!

Features:
- All tools in one screen, including comments


- Unique 'tether' stone and markup placement: play a stone and move your finger away to check and correct the position.Fast for tablets, accurate enough for a 25x25 game on a 320x480 screen!


- Correction for involuntary movements while lifting your finger


- Adjustable screen colors


- Use the BW-DGS plugin (separate download) to make your moves on the turn-based Dragon Go Server! Check it out on the Play Store for details.


- Use a bot player (separate download) as an opponent or analysis helper. The bot is activated as just another tool, to be used in any SGF!Check out BW-Gnu Go on the Play Store for details.


- Study joseki while analysing your games using embedded Kogo's Joseki Dictionary, March 6 2013 version.KJD included by courtesy of Alexander Dinerchtein, curator, and Gary Odom, originator. http://waterfire.us/joseki.htm


- Landscape support on both phones and tablets


- Record your own games


- Game review/study: replay a game on the board while the app only accepts the game moves. Ask for hint: show 5x5 square containing next move (size adjustable in settings)


- Score and score estimate (manual marking of dead stones)


- Easy creation and browsing of variations without unnecessary pop-ups


- Mark moku with letters, digits and shapes


- Game editing: add and remove stones, correct earlier moves (checks if this results in impossible moves later)


- Supports game collections in single SGF, like the ones at http://webdocs.cs.ualberta.ca/~mmueller/go/games.html


- Also supports old SGF formats (pre-FF[4]). Please report any incompatible SGF's!

Well designed. Works well. Great with free plugins that add ability to play against a bot or play an opponent on the Dragon Go server.

Easily the best SGF editor/viewer that I've found so far, and I've tried most of them now.

Very good sgf editor. It could be better if it displayed the variations tree.

Plugins don't work

There is a GUI problem with showing a board on Android 10, Samsung SM-T865 tablet

I tried to repeatedly play 9x9 games against gnugo. Every second game started so that i could not play, offered to save the score again, and crashed.

Mon. P. Jun 16, 2019     

I'm loving the new updates.

Gez. B. Apr 21, 2019     

Great app, thank you. Would you consider putting the "skip game" button back on top so one only needs to click once?

Bra. R. Apr 7, 2019     

Very nice program and still actively maintained. It's the best Android program for replaying games with the guess the move feature and optional hints. It would be nice to have Pachi included as an extension again, since it has had some active development and is quite nice.

love the new interface so far! Although not sure how to start a new game with the gnu-bot

I like this app for reviewing games, mostly because it has a well thought out, simple, guess the next move feature, and an attractive looking board. With the latest version the author has listened to user feedback and made changes that addressed the weaknesses of the old version. Very very happy now and I am hard to satisfy.

Beautiful app for reviewing commented games (variation functionality is best I've seen so far) DGS plugin works great (had a little trouble switching users once but just uninstalled the plugin reinstall fixed). If only could us it for OGS as well (they don't think they need an app which perhaps is true for 9x9 and 13x13 boards but I find 19x19 board completely unusable on my phone).

Excellent app. The tether system of placing stones is the best I've ever come across, very intuitive and works superbly. There are numerous options to expand the app too, including a plugin for the Dragon Go Server which I use all the time, and a Joseki database, which again works superbly. I've only come across one minor issue. When playing a handicap game, once blacks handicap stones have been placed, white should be the first to play, but the app doesn't seem to know this and waits for black to play first. This is incorrect. It's easily solved by forcing the app to play(when it places another black stone), then hit the back/undo button and force it to play again(when it place the correct white stone). This is something that needs to be fixed though since the above is just a workaround. I'm pretty sure it's a bug. Great app though. Highly recommended.

Excellent go editor and really the only one that allows smooth and complex work with any saved game and supports creating own alternative branches within any game. The only little thing to work on is the placement of the forward/back arrows.

Jon. D. Sep 6, 2016     

I like using this on my android phone or tablet. It's particularly useful as you can try various possible scenarios before you play.

Fed. F. Jun 24, 2015     

It's the best. Only two flaws: there is no auto-move play and the joseki section gives error very often. The developers are working very hard. Thanks a lot.

Mic. M. Mar 24, 2017     

Awesome app, there are a few bugs (tapping the board in score estimation mode crashes), and occasionally the controls are a bit touchy, but this is still hands-down the best Go app I've ever used & I use this one daily.

A. G. u. Nov 2, 2016     

Neat, precise, basically everything I need in a go app. The joseki library is a huge plus. Thank you.

Duk. B. Mar 21, 2018     

I'm a complete go novice. I like the way comments can be reviewed versus other apps. I would like for the Tsumego to be built in.

A. G. u. Jul 7, 2015     

Pretty much what I said about the free version. It's my go to app for Dragon.

Fre. D. Dec 4, 2015     

Invaluable Study Tool I use this app every day to review games, record the games from books, and set up tsumego. It always works flawlessly. Thank you so much!!

Era. B. Apr 22, 2017     

Opens .sgf files and is so easy to use! Great for learning. Includes many juseki with comments.

Iva. T. Jul 12, 2015     

I particularly like the ability to study games.

Rya. B. Nov 13, 2017     

Very nice SGF editor, with great add-ons for playing AI or on DGS.

Yak. D. Dec 21, 2015     

I love the dgs integration -- it has completely revolutionized how I play go online!

Fra. A. Dec 26, 2016     

Great to play in,allows DGS compatibility which means I can play with friends on iOS
