# NAS Pro vs Studio PDF

The clearest difference is update cadence: Studio PDF at every 3 days against NAS Pro's every 3 weeks. NAS Pro's advantage is device support (3 vs 1). On price, ads, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. NAS Pro sells 10 in-app purchases, starting at $2.49 per month and Studio PDF sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

NAS Pro ships an update every 3 weeks, Studio PDF every 3 days. The most recent releases landed on September 25, 2026 and September 21, 2026 respectively.
