# My Data Usage vs Charger Master

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.

Both are free to download. My Data Usage sells 1 one-off in-app purchase and Charger Master sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

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.

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.
