Verdict
The clearest difference is in-app purchases: C# .NET at none against Interview Prep's 2. C# .NET also leads on ads (none vs shown) and iOS requirement (14.2 vs 17.0). Interview Prep's advantage is update cadence (every 4 weeks vs every 6 months). On price and device support there is nothing between them.
