Life In 19x19 :: "A Master of Go", iOS/iPadOS Go AI app

The app itself works well on iPhone, but 19x19 board is too big for iPhone at present.
So I gave up to release the app as universal one.
I will devise user interface for users to play more easily.
Please wait for a while.

dng88 san,

Thank you for purchasing my app!
I will consider about ponder on/off.
Currently the app uses 1/3 memory in your iPad and the engine will stop when thr memory runs out for tree nodes. For 4GB iPad, maximum nodes are about 90,000.

Switching blank board and study board is interesting!
If you have another go board app, you may like to use both that app and my app by slide over or split view.

About variation, I am not quite sure if I understand your questions correctly.
To see variation, touch numbers(1234)button and touch a candidate move which you are interested in.
I think that the meaning of variation is the reasoning of the winrate of the candidate.
I hope that my answer makes sense for you.

Thank you!

Kaliwan san,

In my investication, the file format which Pandanet uses is not SGF, it is UGF.
I am sorry that currently my app does not support UGF.

There seems to be several converter programs between UGF and SGF.
Converting UGF to SGF, and converting some character code to UTF-8,
then your UGF file will be used on my app.

Sorry for inconvenience.
I hope that this information will be some helps for you.

Could you put your rating for my app in App Store?

Awesome! I've bought it and analyzed two games so far. Now I just need a new iPhone. Can anyone comment on how fast it does playouts on an XR or XS?

Grünauer san, My app uses Core ML. (It works on both iOS11 and iOS12) I developed the engine on macOS originally, and supporting GTP itself is not hard. But on my iMac(pretty old, late 2012), the performance was 1/3 times worse than Leela Zero. Currently there are no meanings to use the eingine for Lizzie. Leela Zero is well tuned, so my engine is not good alternative until Apple removes OpenCL. When GPU version of LZ become not available on macOS, I may consider. Thank you!

I'm know it's a ton of work to take a working iPad design and make an iPhone one--almost likely starting from scratch for the UI.

Can you save the game Sgf especially those varaiotioj I put in. Seems no way to save files. In fact for the future like Lizzie better to have a button for option (like the x key but obvious ipad use button). Great app.

Grünauer san, Thank you for your continuing reviewｓ! The comments of you and other people have been filed as github issues. https://github.com/new3Rs/a_master_of_go/issues I will consider back functionality in play mode. About landscape mode, all two points are intended ones as the last resort^^; I wanted to support split view, which requires apps to support landscape. It looks not good, but buttons will escape from back of board to left-side. I will consider improvements of landscape. Thank you!

dng88 san, I am sorry for the lack of functionalities to export or save SGFs. I will consider to put them in the next major version. Thank you! I hope that you will enjoy Go better with my app.

casch san, SGF generated by KGS has invalid properties in root node, PC and C. They includes ":" without escaping. If you remove these properties by editing, my app can accept the edited one. I am sorry for inconvenience. I will put a workaround for it. Thank you!

Hello, everyone. The first update has been released! Here is a changelog. - bug-fix that previous variation remained in candidate variation mode. - improved English and Chinese. - take-back functionality in play mode. Please touch the stone you played just before. - improved UI for viewing AI self-play - bug-fix that could not read SGF with Windows new line(CRLF) - try to read invalid SGFs I appreciate everyone here to report these issue and hope that you guys like my app more. And may I ask you a favor? My app have gotten only three ratings in App Store... The number of installed is not shown in App Store, so the number of ratings is an alternative impression for new customers. Could you put your rating for my app in App Store? Thank you!

Could it be that it’s not available in the German App store? I just searched it with my new-ish iPhone 7 and all it offers was Master of Gomoku And may I suggest that you edit the first post’s subject line so that it contains the app’s name? (And since it now is for iPhone also you could also replace “for iPad” with “for iOS”.) Regards, Tom

Bonobo san, I am sorry for forgetting the app URL. Could you try the following URL for German? https://itunes.apple.com/de/app/%E5%9B% ... 35374?mt=8 Certainly I will try to edit the subject of the first post!^^

On An Empty Board iPhone 5s, 1.1 N/s iPhone 6 Plus, 1.4 N/s iPhone X, 13-15 N/s iPhone Xs Max, 130-160 N/s iPad Air 2, 2.6 N/s For Devices Lower than A12 it will be nice to be able to start the study on demand else its impossible to scroll all the way to the move you really want to study The magnifying option should be disabled by default on iPads Thanks !!!

Post subject:	Re: A Go AI app for iOS with that strong neural network
hyperpage san, Thank you for purchasing my app! I am asking my users to tell me nps on Twitter if they have XR or XS, but currently no responses... In my estimation based on the comparison between A12X and A12, XR or XS will achieve about 100 nps. But I am not sure. When I get some related information, I will tell you it. Thank you!

Post subject:	Re: A Go AI app for iOS with that strong neural network
casch san, Thank you for rating my app! And also thank you for information about iPhone X. It is quite helpful for me. Nps means number of playouts per sencond. In the time parity condition, large nps means strong. Or you can get a certain search result quickly if nps is large. (Even if nps is not large on your device, giving the app time eventually let the app show similar result as powerful devices.) Thank you!
