Verdict
The clearest difference is in-app purchases: LumoTalk at none against PDF翻译's 3. LumoTalk also leads on ratings volume (6 vs 1). PDF翻译's advantage is rating (5.0 vs 4.7) and update cadence (every 3 days vs every 2 weeks). On price, ads, device support and iOS requirement there is nothing between them.

PDF翻译 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: LumoTalk has 6 ratings behind it against 1, so its average is the more settled of the two.
LumoTalk ships an update every 2 weeks, PDF翻译 every 3 days. Both last shipped on October 24, 2026.
