# Deep Whois vs Power PDF

The clearest difference is rating: Power PDF at 4.8 against Deep Whois's 4.5. Power PDF also leads on ratings volume (1K vs 172). Deep Whois's advantage is review sentiment (85% vs 65%) and iOS requirement (13.4 vs 16.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Deep Whois sells 4 in-app purchases, starting at $1.99 per 7 days and Power PDF sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Power PDF holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Power PDF has 1K ratings behind it against 172, so its average is the more settled of the two. Written reviews complicate that: 85% of Deep Whois's written reviews are positive against 65% of Power PDF's, so the app with the better star average is not the one people write more warmly about.

Deep Whois ships an update every 4 months, Power PDF every 3 months. Both last shipped on October 23, 2026.
