Smartgo Kifu
Every update of this app is just amazing - the book-like diagrams are just great when you are looking at commented games, this is the feature which is updated all the time, and it's just being better and better. Because of this I have almost forgotten about my desktop and all my go activity is through iPad now.
You can zoom in /out diagrams, there are clear and visible options on how scroll through a game in diagrams and there are a lot of other goodies. Essential app.
TengenGo
Good but still has a bugs - new update come out some time ago but there are still following bugs:
1) Diacritic signs/characters form non english language are crashing the app (try use this : ąęółćń)
2) Sometimes stones are not removed correctly while observing games.
3) Chat outside of game - great but need to be some kind of list of messages, if you touch the screen outside chat box it will disappear and you just can't simply go back to chat with the same person
4) Still the game requests are so annoying - they just block all other functions of this app. You can do game request only or something else, but not both thing at the same time, this process should be backgrounded.
5) buggy & strange behavior of app if 'observe' command is used via terminal. This is very nice that 'Terminal" is available but here is example of issues :
1. You are listed as a player in the observed game. You can try to pass, to resign or even undo , but you can't leave observed game.
2. Stones are not displayed correctly - only the most current are visible since you observe this particular game.
3. If you try to enter 'observe' command for more than one game then you will get strange mix of these games. If you change orientation you will get game information from the other game.
4. If you have any adjourned game then after "observe" command you will get a mix of these two games: yours and the one you wanted to observe. Stones are taken form your adjourned game and the new moves will show on the board as they are played on the observed game.
5. If there is some special tournament these games are not vissible on the main room and you can't observe such games in a normal way. But if you know the number of this game you can open it via terminal. But - again - all issues listed above are still there.
And the biggest issue - developer of this app doesn't like to answer e-mails with list of bugs...
Tetsuki for iPad
- still is beta and WIP but it's a great app, with no problems like these listed above. For iPad version look at the fanpage on facebook - you need to provide your IMEI to the developer of this app to install beta version.
1) Diacritic signs/characters - work great, and don't crash app
2) no problem with removing of stones in observed games
3) game requests are backgrounded,
It's the best looking IGS client on mobiles/tablets and has best functionality of all other apps. Developer of Tetsuki is an open person and he is always available through e-mail, facebook etc. He listens to user's complaints and still improving this app.
The only one minus is that you can't open special games in tetsuki, but I think it will be implemented in the final release.
