Verdict
The clearest difference is price: Zima Client at Free against iTest.'s $0.99. Zima Client also leads on rating (4.8 vs 4.4) and update cadence (fortnightly vs every 2 months). iTest.'s advantage is review sentiment (84% vs 59%) and iOS requirement (9.0 vs 16.0). On ads, in-app purchases, monetization model and device support there is nothing between them.
