# Charger Master vs BimmerRefs

The clearest difference is price: Charger Master at Free against BimmerRefs's $3.99. Charger Master also leads on rating (4.3 vs 3.9) and ratings volume (6.1K vs 7). BimmerRefs's advantage is in-app purchases (none vs 2) and ads (none vs shown). On update cadence and device support there is nothing between them.

Charger Master is free to download; BimmerRefs costs $3.99 up front. Charger Master sells 2 one-off in-app purchases. BimmerRefs asks for nothing beyond the download.

Charger Master holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Charger Master has 6.1K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 27% of Charger Master's written reviews are positive against 57% of BimmerRefs's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 weeks. Both last shipped on October 16, 2026.
