Verdict
The clearest difference is price: Breaker Box at Free against GenCheck's $3.99. Breaker Box also leads on ratings volume (107 vs 1). GenCheck's advantage is rating (5.0 vs 4.4) and update cadence (every 2 days vs every 10 days). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
