Zurichess keeps travelling through Switzerland. Latest station is Geneva and we've just received an Android version compiled by Jim Ablett. I guess it's an arm5 build but i'm not sure as the binary did not disclose any trace like previous ones.
Regarding the strength, some 30-50 ELO more may be expected according to the improvements mentioned by the author. I would be glad to test and verify this quickly but i'm too close to a new Rapidroid release including Fribourg version. That's why Geneva will be replacing Fribourg later on.
In the meantime, you may download and try Geneva: HERE
