Verdict
The clearest difference is rating: OpenSolar at 4.4 against Terros's 3.8. OpenSolar also leads on in-app purchases (none vs 4) and iOS requirement (15.7 vs 17.0). Terros's advantage is update cadence (every 4 days vs every 6 weeks) and ratings volume (99 vs 10). On price, review sentiment, ads and device support there is nothing between them.

OpenSolar ships an update every 6 weeks, Terros every 4 days. The most recent releases landed on October 7, 2026 and October 14, 2026 respectively.
