Verdict

The call

KiraFlow and Particle Simulation both sit at 4.6 stars, but that hides the real split: 78% of KiraFlow's written reviews are positive against 25% of Particle Simulation's. KiraFlow also leads on update cadence (every 2 months vs every 7 months) and ratings volume (315 vs 46). Particle Simulation's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price, rating, in-app purchases and monetization model there is nothing between them.
