Verdict

The call

The clearest difference is rating: ChargerSync at 4.8 against Polestar's 4.4. ChargerSync also leads on iOS requirement (15.3 vs 17.0). Polestar's advantage is review sentiment (32% vs 7%) and ratings volume (3.5K vs 46). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

ChargerSync holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Polestar has 3.5K ratings behind it against 46, so its average is the more settled of the two. Written reviews complicate that: 32% of Polestar's written reviews are positive against 7% of ChargerSync's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Polestar ships an update every 3 weeks, ChargerSync every 2 months. The most recent releases landed on October 29, 2026 and October 25, 2026 respectively.
