Verdict

The call

The clearest difference is monetization model: Io Ninja Games at free with in-app purchases against String.io's subscription. Io Ninja Games also leads on iOS requirement (11.0 vs 15.0). String.io's advantage is rating (4.5 vs 4.1) and update cadence (every 3 months vs every 13 months). On price, ads, in-app purchases and device support there is nothing between them.
