# Solar App vs WattCycle

The clearest difference is rating: Solar App at 3.1 against WattCycle's 2.0. Solar App also leads on iOS requirement (12.0 vs 16.0). WattCycle's advantage is update cadence (every 9 days vs every 3 weeks) and review sentiment (10% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Solar App holds the better App Store score, 3.1 against 2.0. Both are backed by a comparable volume of ratings — 14 and 48 respectively. Written reviews complicate that: 0% of Solar App's written reviews are positive against 10% of WattCycle's, so the app with the better star average is not the one people write more warmly about.

Solar App ships an update every 3 weeks, WattCycle every 9 days. The most recent releases landed on October 4, 2026 and October 14, 2026 respectively.
