Verdict
The clearest difference is in-app purchases: Nuthin at none against Fluid Simulation's 15. Nuthin also leads on ads (none vs shown). Fluid Simulation's advantage is update cadence (daily vs every 2 weeks) and ratings volume (90K vs 5). On price, rating, review sentiment and device support there is nothing between them.
