Verdict
The clearest difference is price: Help Assist at Free against Ultrasonic Repeller's $0.59. Help Assist also leads on rating (5.0 vs 3.6). Ultrasonic Repeller's advantage is update cadence (every 2 months vs every 21 months) and ratings volume (50 vs 2). On ads, in-app purchases, monetization model and device support there is nothing between them.
