Hactar Go is an application for Android.

A 'Lite' version which is free is also available.

"Differences between Hactar Go full version and Hactar Go Lite:
1. The full version has a go opponent for 13x13 and 19x19 boards (subscription in Lite).
2. The full version has internet game search (subscription in Lite).
