# ScanGuru vs FlowPDF

The clearest difference is ratings volume: ScanGuru at 93K against FlowPDF's 2.2K. ScanGuru also leads on review sentiment (48% vs 35%) and chart position (#26 vs unranked). FlowPDF's advantage is iOS requirement (13.0 vs 16.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. ScanGuru sells 13 in-app purchases, starting at $6.99 per 7 days and FlowPDF sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ScanGuru holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: ScanGuru has 93K ratings behind it against 2.2K, so its average is the more settled of the two. Written reviews point the same way: 48% of ScanGuru's written reviews are positive against 35% of FlowPDF's.

ScanGuru ships an update every 10 days, FlowPDF every 9 days. The most recent releases landed on September 28, 2026 and September 29, 2026 respectively.
