# OBD JScan vs Auto101 Pro

The clearest difference is in-app purchases: Auto101 Pro at none against OBD JScan's 8. Auto101 Pro also leads on review sentiment (100% vs 80%) and rating (5.0 vs 4.7). OBD JScan's advantage is ratings volume (1.3K vs 5) and iOS requirement (13.0 vs 16.0). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. OBD JScan sells 7 one-off in-app purchases. Auto101 Pro asks for nothing beyond the download.

Auto101 Pro holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: OBD JScan has 1.3K ratings behind it against 5, so its average is the more settled of the two.
