Verdict

The call

The clearest difference is in-app purchases: 3Cs at none against BoldVoice's 16. 3Cs also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.5). BoldVoice's advantage is update cadence (every 2 days vs every 9 days) and chart position (#111 vs unranked). On price and device support there is nothing between them.
