Verdict

The call

The clearest difference is rating: Curenergía at 4.9 against i's 3.0. Curenergía also leads on ratings volume (38 vs 2). i's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, review sentiment, in-app purchases and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Curenergía holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: Curenergía has 38 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 23% of i's written reviews are positive against 17% of Curenergía's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

i ships an update every 3 weeks, Curenergía every 3 months. The most recent releases landed on September 4, 2026 and June 30, 2026 respectively.
