Verdict
The clearest difference is rating: PDF翻译 at 5.0 against 沉浸式翻译's 4.3. PDF翻译 also leads on update cadence (every 3 days vs weekly). 沉浸式翻译's advantage is ratings volume (26 vs 1) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. 沉浸式翻译 sells 3 in-app purchases, starting at $3.99 per month and PDF翻译 sells 3 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
PDF翻译 holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: 沉浸式翻译 has 26 ratings behind it against 1, so its average is the more settled of the two.
沉浸式翻译 ships an update weekly, PDF翻译 every 3 days. The most recent releases landed on October 24, 2026 and October 30, 2026 respectively.
