Verdict
The clearest difference is in-app purchases: Guerrillazen at none against Posture AI's 6. Guerrillazen also leads on rating (5.0 vs 4.7) and device support (4 vs 1). Posture AI's advantage is ratings volume (229 vs 17) and update cadence (every 3 weeks vs every 2 months). On price and ads there is nothing between them.
