Verdict
The clearest difference is rating: CTR at 4.9 against EDP Solar's 3.5. EDP Solar's advantage is update cadence (every 5 weeks vs every 9 months) and review sentiment (8% vs 0%). On price, ratings volume, ads and in-app purchases 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.
CTR holds the better App Store score, 4.9 against 3.5. Both are backed by a comparable volume of ratings — 15 and 6 respectively. Written reviews complicate that: 0% of CTR's written reviews are positive against 8% of EDP Solar's, so the app with the better star average is not the one people write more warmly about.
CTR ships an update every 9 months, EDP Solar every 5 weeks. The most recent releases landed on September 25, 2026 and September 18, 2026 respectively.
