Verdict
The clearest difference is rating: Fail Run at 4.7 against Death Book's 2.7. Fail Run also leads on ratings volume (34K vs 129) and update cadence (every 5 weeks vs every 4 months). Death Book's advantage is in-app purchases (none vs 1). On price, ads, device support and iOS requirement there is nothing between them.
