Verdict
The clearest difference is in-app purchases: 1Howz at none against My Solar Panel's 2. 1Howz also leads on ads (none vs shown) and update cadence (every 5 days vs every 2 months). My Solar Panel's advantage is ratings volume (110 vs 1) and iOS requirement (13.2 vs 15.5). On price and device support there is nothing between them.
