# PDF Master vs 好用电话

The clearest difference is review sentiment: 好用电话 at 90% against PDF Master's 40%. 好用电话 also leads on update cadence (every 10 days vs every 2 months). PDF Master's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. PDF Master sells 13 in-app purchases, starting at $2.99 per 7 days and 好用电话 sells 24 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Master ships an update every 2 months, 好用电话 every 10 days. The most recent releases landed on October 26, 2026 and October 30, 2026 respectively.
