Verdict

The call

The clearest difference is in-app purchases: Gravitarium at none against Fluid Simulation's 3. Gravitarium also leads on ads (none vs shown) and device support (5 vs 3). Fluid Simulation's advantage is update cadence (every 2 days vs every 3 months) and rating (4.9 vs 4.5). On price there is nothing between them.
