Verdict

The call

The clearest difference is rating: OpenSolar at 4.4 against Coperniq's 1.0. OpenSolar also leads on ratings volume (10 vs 1) and iOS requirement (15.7 vs 17.0). Coperniq's advantage is review sentiment (82% vs 45%) and update cadence (every 9 days vs every 6 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

OpenSolar holds the better App Store score, 4.4 against 1.0. That said, the two scores are not equally well evidenced: OpenSolar has 10 ratings behind it against 1, so its average is the more settled of the two. 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.

UpkeepUpdate frequency

OpenSolar ships an update every 6 weeks, Coperniq every 9 days. The most recent releases landed on October 7, 2026 and October 8, 2026 respectively.
