Verdict

The call

The clearest difference is in-app purchases: Ruby at none against Instock's 1. Ruby also leads on ads (none vs shown) and review sentiment (100% vs 75%). Instock's advantage is iOS requirement (13.0 vs 16.0). On price, rating, update cadence and device support there is nothing between them.
