Verdict
The clearest difference is rating: Smart Solar + at 5.0 against WatchPower's 2.5. Smart Solar + also leads on update cadence (every 2 weeks vs every 3 months). WatchPower's advantage is ratings volume (73 vs 2) and iOS requirement (11.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
