# FIXD OBD2 Scanner vs Sigma Mini

The clearest difference is in-app purchases: Sigma Mini at none against FIXD OBD2 Scanner's 3. Sigma Mini also leads on rating (5.0 vs 4.6) and iOS requirement (11.0 vs 18.0). FIXD OBD2 Scanner's advantage is update cadence (weekly vs every 2 months) and ratings volume (26K vs 2). On price, ads and device support there is nothing between them.

Both are free to download. FIXD OBD2 Scanner sells 3 in-app purchases, starting at $7.99 per 7 days. Sigma Mini asks for nothing beyond the download.

Sigma Mini holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: FIXD OBD2 Scanner has 26K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 60% of FIXD OBD2 Scanner's written reviews are positive against 38% of Sigma Mini's, so the app with the better star average is not the one people write more warmly about.

FIXD OBD2 Scanner ships an update weekly, Sigma Mini every 2 months. The most recent releases landed on October 15, 2026 and October 1, 2026 respectively.
