## A Master of Go Description
It is a Go AI featuring a neural network of that strong, open source AI. Leela Zero, ELF OpenGo, PhoenixGo, Minigo, SAI, and optionally KataGo!

You can use it as a strong opponent, and as a good teacher at the time of study.

With M2 processor of iPad Pro, the playouts are performed over 650 times per second with ELF OpenGo weight v1, and with A15 Bionic processor of iPad mini, over 200 times per second! Both exceed notebook computers and is comparable to desktop computers. With M2 processor of iPad Pro,  the playouts are performed over 250 times per second with KataGo b18c384nbt!
Other famous weights are also included.

For your information, the playout speed on the iPad Pro 9.7 inch model(A9X processor) will be about 10 times per second, and the one on the iPhone 6(A8 processor) will be about 1 time per second. I think that even so it is stronger than most amateurs, but I am sorry that patterns of misreading ladders will increase.
Please be careful when considering purchasing.

Enjoy it!

## A Master of Go Reviews in Vereinigtes Königreich

### ***** "Nice app for iOS"
Runs well on iPad. Might exhaust iPhone battery a bit but depends on what version of iPhone and AI
-- ywca9813, 2024-01-02

### ***-- "Could be good in the future"
This is still a bit lacking in features, though excellent otherwise. It needs a tree viewer and the ability to pause analysis (like the space bar in Lizzie). Those are most pressing since it isn’t possible to do serious analysis without them. I paid for it and am not asking for my money back but I am hoping that the developer will speedily add these key functions and make this the best go analysis app available. Oh, and I also meant to add that it would benefit from some instructions someplace. Note added: I took a look at the website and it speaks of the 1-2-3-4 modes to toggle views. I can only see 1-2 (two modes) and toggling they don’t make any visible changes. Am I missing something? Also there is a small pair of scales (it refers to how many coins I have left) - I have no idea what that is. HELP PLEASE!

Note added after developer response: pausing the analysis is not for battery life, it is more to have an uncluttered display. Is there a way to switch on/off the candidate moves in analysis. I like to work out the move and then see how good my choice was.
