# Scan Master vs UPDF

The clearest difference is ads: UPDF at none against Scan Master's shown. UPDF also leads on ratings volume (697 vs 1) and update cadence (fortnightly vs every 2 months). Scan Master's advantage is rating (5.0 vs 4.6). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Scan Master sells 1 one-off in-app purchase and UPDF sells 13 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Scan Master holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: UPDF has 697 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of Scan Master's written reviews are positive against 84% of UPDF's, so the app with the better star average is not the one people write more warmly about.

Scan Master ships an update every 2 months, UPDF fortnightly. The most recent releases landed on October 9, 2026 and October 27, 2026 respectively.
