I've just learned that AQ has been ported on Android phones, and it works very well !
It's full of nice features, and seems super strong.

You can download AQ-Android HERE

I had it play at H4 (!) against CSDL 2dan.
AQ-Android settings were
depth 3 (max=6)
search extent 3 (max=6)
search accuracy 4 (max=4)
AQ was white, and won easily

The game is HERE

Some of the features :
handicaps (H0 -> H9), 3-way adjustable playing level, 2 or 3 goban and stones styles, variations, time-graph, score estimator, win %, etc.


Only drawback : most of the menus are in chinese, but I've had a bit of help from gjchangmu at Reddit to translate what was not obvious.

Some screenshots, with translations (correct me if it's wrong)

All this in your phone... Woaw... Congratulations to the developer !

NB. I first heard of it thanks to alredydone00, in Reddit (cbaduk)

Forget all the above, there's already someone who made an English version !

HERE

If you have installed the chinese version, you have to uninstall it first, before installing this english version.

Where can we get official information about this app?
(Otherwise, how could we trust it?)

I don't think there's "official" information.
I've installed it and scanned my phone just in case, it's perfectly ok.
You can find info about the developer and the translator at reddit (cbaduk)

Its almost pro level on the huawei phone with AI chip
