# Deduce vs Puralax

The clearest difference is price: Puralax at Free against Deduce's $2.99. Puralax also leads on ratings volume (30 vs 3). Deduce's advantage is rating (4.7 vs 4.5) and chart position (#117 vs unranked). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.

Puralax is free to download; Deduce costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Deduce holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Puralax has 30 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 88% of Deduce's written reviews are positive against 90% of Puralax's, so the app with the better star average is not the one people write more warmly about.

Deduce ships an update every 4 months, Puralax every 2 months. The most recent releases landed on September 21, 2026 and September 24, 2026 respectively.
