Verdict
The clearest difference is review sentiment: Overkill Solar at 100% against Winergy's 25%. Overkill Solar also leads on ratings volume (16 vs 2) and iOS requirement (13.4 vs 15). Winergy's advantage is rating (5.0 vs 4.7) and update cadence (every 6 weeks vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Winergy holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Overkill Solar has 16 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Overkill Solar's written reviews are positive against 25% of Winergy's, so the app with the better star average is not the one people write more warmly about.
Overkill Solar ships an update every 4 months, Winergy every 6 weeks. The most recent releases landed on September 28, 2026 and October 8, 2026 respectively.
