Verdict

The call

The clearest difference is review sentiment: Starfall at 73% against Kids A's 35%. Starfall also leads on rating (4.1 vs 3.6). Kids A's advantage is monetization model (free vs freemium) and update cadence (every 3 weeks vs every 2 months). On price, ratings volume, ads and in-app purchases there is nothing between them.
