Verdict
The clearest difference is update cadence: Streaklet at weekly against Z's every 2 months. Streaklet also leads on review sentiment (100% vs 83%) and rating (5.0 vs 4.8). Z's advantage is ratings volume (433 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
