Verdict
The clearest difference is rating: Offline AI Voice Recorder at 4.9 against PDF OCR's 4.4. Offline AI Voice Recorder also leads on in-app purchases (none vs 3) and iOS requirement (15.0 vs 17.0). PDF OCR's advantage is ads (none vs shown) and review sentiment (100% vs 83%). On price, ratings volume, update cadence and device support there is nothing between them.
