Verdict
The clearest difference is rating: PDF翻译 at 5.0 against Trancy ET's 3.3. PDF翻译 also leads on update cadence (every 3 days vs every 5 weeks). Trancy ET's advantage is ratings volume (15 vs 1). On price, ads, in-app purchases and monetization model 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. Trancy ET sells 2 in-app purchases, starting at $2.99 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 3.3. That said, the two scores are not equally well evidenced: Trancy ET has 15 ratings behind it against 1, so its average is the more settled of the two.
Trancy ET ships an update every 5 weeks, PDF翻译 every 3 days. The most recent releases landed on October 24, 2026 and October 30, 2026 respectively.
