# PDF vs Voice Writer

The clearest difference is ads: PDF at none against Voice Writer's shown. Voice Writer's advantage is update cadence (every 2 days vs every 2 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. PDF sells 4 one-off in-app purchases and Voice Writer sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

PDF ships an update every 2 months, Voice Writer every 2 days. The most recent releases landed on October 24, 2026 and October 18, 2026 respectively.
