# SUP vs OpenOBD

The clearest difference is in-app purchases: SUP at none against OpenOBD's 1. SUP also leads on rating (5.0 vs 4.8) and iOS requirement (13.0 vs 16.4). OpenOBD's advantage is update cadence (weekly vs every 5 weeks) and ratings volume (5 vs 1). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. OpenOBD sells 1 one-off in-app purchase. SUP asks for nothing beyond the download.

SUP holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: OpenOBD has 5 ratings behind it against 1, so its average is the more settled of the two.

SUP ships an update every 5 weeks, OpenOBD weekly. The most recent releases landed on November 4, 2026 and November 10, 2026 respectively.
