Verdict
The clearest difference is review sentiment: Email Cleaner at 60% against UserCrowd's 0%. Email Cleaner also leads on rating (4.6 vs 2.7) and ratings volume (830 vs 10). UserCrowd's advantage is in-app purchases (none vs 13) and update cadence (every 4 days vs every 2 weeks). On price, ads, device support and iOS requirement there is nothing between them.
