Verdict
The clearest difference is review sentiment: Coperniq at 82% against OpenSolar's 45%. Coperniq also leads on update cadence (every 9 days vs every 6 weeks). OpenSolar's advantage is rating (4.4 vs 4.2) and iOS requirement (15.7 vs 17.0). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
OpenSolar holds the better App Store score, 4.4 against 4.2. Both are backed by a comparable volume of ratings — 10 and 6 respectively. Written reviews complicate that: 45% of OpenSolar's written reviews are positive against 82% of Coperniq's, so the app with the better star average is not the one people write more warmly about.
OpenSolar ships an update every 6 weeks, Coperniq every 9 days. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
