# My Solar Panel vs 1Howz

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.

Both are free to download. My Solar Panel sells 2 in-app purchases, starting at $9.99 per month. 1Howz asks for nothing beyond the download.

1Howz holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: My Solar Panel has 110 ratings behind it against 1, so its average is the more settled of the two.

My Solar Panel ships an update every 2 months, 1Howz every 5 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
