Verdict
The clearest difference is in-app purchases: GyroAssistant at none against Project Iris's 1. GyroAssistant also leads on iOS requirement (14.1 vs 17.0). Project Iris's advantage is update cadence (every 4 days vs every 11 months) and ratings volume (13 vs 1). On price, rating, review sentiment and ads there is nothing between them.
