Verdict
The clearest difference is review sentiment: Stemwise at 100% against Watts® Home's 28%. Stemwise also leads on rating (5.0 vs 4.6) and update cadence (every 5 days vs every 3 months). Watts® Home's advantage is ads (none vs shown) and ratings volume (4.1K vs 1). On price, in-app purchases and device support there is nothing between them.
