# DejaVocab vs INYU

The clearest difference is rating: DejaVocab at 4.6 against INYU's 4.0. DejaVocab also leads on ratings volume (61 vs 3). INYU's advantage is monetization model (free vs freemium) and update cadence (every 3 days vs weekly). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. DejaVocab sells 6 in-app purchases, starting at $5.99 per month and INYU sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

DejaVocab holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: DejaVocab has 61 ratings behind it against 3, so its average is the more settled of the two.

DejaVocab ships an update weekly, INYU every 3 days. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
