Verdict
The clearest difference is in-app purchases: G at none against CallYou's 6. G also leads on ads (none vs shown) and review sentiment (28% vs 14%). CallYou's advantage is update cadence (every 3 weeks vs every 6 weeks). On price, device support and iOS requirement there is nothing between them.
