Recognition and search run on the device; screen frames are not saved or uploaded. Try Pro free for 3 days from your first use of a Pro feature. A one-time purchase then unlocks Pro for life. No subscription and no automatic charge when the trial ends. Previous AI Coach purchasers keep access to Pro. Games, ladder challenges, basic game records and local network play remain free.

Verdict
The clearest difference is in-app purchases: Space Interface at none against OneSolve Gomoku's 1. Space Interface also leads on device support (3 vs 1) and iOS requirement (12.0 vs 17.0). OneSolve Gomoku's advantage is update cadence (every 3 days vs every 8 months). On price and ads there is nothing between them.
