# PDF Voice Reader vs Immersive Book Translator

The clearest difference is rating: PDF Voice Reader at 4.1 against Immersive Book Translator's 3.0. PDF Voice Reader also leads on ratings volume (955 vs 4) and review sentiment (22% vs 0%). Immersive Book Translator's advantage is ads (none vs shown) and update cadence (every 8 days vs every 3 weeks).

Both are free to download. PDF Voice Reader sells 16 in-app purchases, starting at $4.99 per month and Immersive Book Translator sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
