Verdict
The clearest difference is review sentiment: Pool Plus at 100% against Pro Series Pool & Spa's 50%. Pool Plus also leads on rating (5.0 vs 4.4) and update cadence (every 6 weeks vs every 4 months). Pro Series Pool & Spa's advantage is price (Free vs $0.99) and ratings volume (10 vs 2). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
