# PDF Reflow vs Quadrix

The clearest difference is rating: Quadrix at 5.0 against PDF Reflow's 3.6. PDF Reflow's advantage is ratings volume (27 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PDF Reflow sells 1 one-off in-app purchase and Quadrix sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Quadrix holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: PDF Reflow has 27 ratings behind it against 2, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 12, 2026 and September 21, 2026 respectively.
