# Graspp Translate vs duoBooks

The clearest difference is review sentiment: Graspp Translate at 100% against duoBooks's 69%. Graspp Translate also leads on iOS requirement (13.0 vs 15.0). duoBooks's advantage is rating (4.7 vs 4.5) and ratings volume (48 vs 15). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Graspp Translate sells 2 in-app purchases, starting at $5.49 per month and duoBooks sells 11 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

duoBooks holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 15 and 48 respectively. Written reviews complicate that: 100% of Graspp Translate's written reviews are positive against 69% of duoBooks's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on August 25, 2026 and September 26, 2026 respectively.
