Verdict

The call

The clearest difference is in-app purchases: IgoStadium at none against Read19's 4. IgoStadium also leads on iOS requirement (10.0 vs 18.0). Read19's advantage is ads (none vs shown) and update cadence (every 2 days vs fortnightly). On price and device support there is nothing between them.
