Verdict
The clearest difference is rating: MaxiAP Diag at 2.9 against Bosch Mobile Scan's 1.9. MaxiAP Diag also leads on update cadence (every 5 months vs every 10 months). Bosch Mobile Scan's advantage is ratings volume (131 vs 10) and review sentiment (11% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Bosch Mobile Scan sells 10 one-off in-app purchases and MaxiAP Diag sells 28 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
MaxiAP Diag holds the better App Store score, 2.9 against 1.9. That said, the two scores are not equally well evidenced: Bosch Mobile Scan has 131 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 11% of Bosch Mobile Scan's written reviews are positive against 0% of MaxiAP Diag's, so the app with the better star average is not the one people write more warmly about.
Bosch Mobile Scan ships an update every 10 months, MaxiAP Diag every 5 months. The most recent releases landed on October 29, 2026 and October 20, 2026 respectively.
