# AIOBD13 vs NexzScan

The clearest difference is review sentiment: AIOBD13 at 50% against NexzScan's 7%. AIOBD13 also leads on iOS requirement (7.0 vs 15.6). NexzScan's advantage is rating (2.1 vs 1.0) and update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

NexzScan holds the better App Store score, 2.1 against 1.0. That said, the two scores are not equally well evidenced: NexzScan has 27 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 50% of AIOBD13's written reviews are positive against 7% of NexzScan's, so the app with the better star average is not the one people write more warmly about.

AIOBD13 ships an update every 2 months, NexzScan every 3 weeks. The most recent releases landed on September 25, 2026 and October 6, 2026 respectively.
