Verdict
The clearest difference is rating: Pre at 5.0 against Johnson Controls CWa's 2.5. Pre also leads on iOS requirement (13.0 vs 16.0). Johnson Controls CWa's advantage is ratings volume (24 vs 1) and update cadence (every 3 months vs every 7 months). On price, ads, in-app purchases and monetization model there is nothing between them.
