Verdict
The clearest difference is in-app purchases: HCJB at none against Voice Training's 2. HCJB also leads on ads (none vs shown) and rating (5.0 vs 4.6). Voice Training's advantage is update cadence (monthly vs every 13 months) and ratings volume (543 vs 1). On price and device support there is nothing between them.
