Verdict
The clearest difference is rating: Use4Free at 4.7 against Danfoss Eco's 4.1. Use4Free also leads on update cadence (every 3 weeks vs every 6 months). Danfoss Eco's advantage is review sentiment (30% vs 0%) and iOS requirement (11.0 vs 16.1). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Use4Free holds the better App Store score, 4.7 against 4.1. Both are backed by a comparable volume of ratings — 43 and 21 respectively. Written reviews complicate that: 30% of Danfoss Eco's written reviews are positive against 0% of Use4Free's, so the app with the better star average is not the one people write more warmly about.
Danfoss Eco ships an update every 6 months, Use4Free every 3 weeks. The most recent releases landed on October 10, 2026 and October 13, 2026 respectively.
