Verdict
The clearest difference is in-app purchases: Chalk Line at none against Nudge's 2. Chalk Line also leads on ads (none vs shown) and ratings volume (396 vs 3). Nudge's advantage is update cadence (daily vs every 3 weeks). On price, rating, review sentiment and device support there is nothing between them.
