Verdict

The call

The clearest difference is monetization model: OHZ Intelligence at free against Pool Shark H2O Pro's free with in-app purchases. OHZ Intelligence also leads on rating (5.0 vs 4.7) and update cadence (every 5 weeks vs every 5 months). Pool Shark H2O Pro's advantage is ratings volume (219 vs 10) and iOS requirement (12.0 vs 15.1). On price, review sentiment, ads and in-app purchases there is nothing between them.
