Verdict

The call

The clearest difference is rating: Charger Master at 4.3 against My Data Usage's 2.8. Charger Master also leads on ratings volume (6.1K vs 23) and update cadence (every 2 weeks vs every 2 months). My Data Usage's advantage is review sentiment (50% vs 27%) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Charger Master holds the better App Store score, 4.3 against 2.8. That said, the two scores are not equally well evidenced: Charger Master has 6.1K ratings behind it against 23, so its average is the more settled of the two. Written reviews complicate that: 50% of My Data Usage's written reviews are positive against 27% of Charger Master's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

My Data Usage ships an update every 2 months, Charger Master every 2 weeks. The most recent releases landed on October 12, 2026 and October 14, 2026 respectively.
