# BimmerRefs vs ASE A

The clearest difference is price: ASE A at Free against BimmerRefs's $3.99. ASE A also leads on rating (4.8 vs 3.9) and ratings volume (664 vs 7). BimmerRefs's advantage is in-app purchases (none vs 4) and update cadence (every 2 weeks vs every 3 months). On review sentiment, ads and device support there is nothing between them.

ASE A is free to download; BimmerRefs costs $3.99 up front. ASE A sells 4 in-app purchases, starting at $6.99 per 7 days. BimmerRefs asks for nothing beyond the download.

ASE A holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: ASE A has 664 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 57% of BimmerRefs's written reviews are positive against 64% of ASE A's.

BimmerRefs ships an update every 2 weeks, ASE A every 3 months. Both last shipped on November 7, 2026.
