# ShiftPower vs PDFlow

The clearest difference is review sentiment: PDFlow at 100% against ShiftPower's 61%. PDFlow also leads on ads (none vs shown). ShiftPower's advantage is in-app purchases (none vs 2) and ratings volume (348 vs 2). On price and update cadence there is nothing between them.

Both are free to download. PDFlow sells 2 one-off in-app purchases. ShiftPower asks for nothing beyond the download.

ShiftPower holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: ShiftPower has 348 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 61% of ShiftPower's written reviews are positive against 100% of PDFlow's, so the app with the better star average is not the one people write more warmly about.

ShiftPower ships an update every 2 weeks, PDFlow weekly. Both last shipped on October 15, 2026.
