# PowerNow vs アイカサ

The clearest difference is rating: アイカサ at 5.0 against PowerNow's 1.0. アイカサ also leads on update cadence (fortnightly vs monthly) and ratings volume (7 vs 1). PowerNow's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, in-app purchases, device support and iOS requirement there is nothing between them.

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

アイカサ holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: アイカサ has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 24% of PowerNow's written reviews are positive against 4% of アイカサ's, so the app with the better star average is not the one people write more warmly about.

PowerNow ships an update monthly, アイカサ fortnightly. The most recent releases landed on October 28, 2026 and October 27, 2026 respectively.
