Verdict

The call

The clearest difference is review sentiment: EE ToolKit at 90% against EnginPrep's 62%. EE ToolKit also leads on rating (4.7 vs 4.4) and ratings volume (1.4K vs 192). EnginPrep's advantage is update cadence (every 3 weeks vs every 3 months). On price, ads, in-app purchases and monetization model there is nothing between them.
