Verdict
The clearest difference is in-app purchases: Petmoji at none against String.io's 4. Petmoji also leads on ads (none vs shown) and update cadence (every 2 days vs every 3 months). String.io's advantage is iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.
