Review momentum
58/100
faster than 64% of Sports apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

From recent reviews.
About A Master of Go S
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!
