# viviTalk vs DejaVocab

The clearest difference is rating: DejaVocab at 4.6 against viviTalk's 4.2. DejaVocab also leads on ratings volume (67 vs 5). viviTalk's advantage is review sentiment (96% vs 87%) and iOS requirement (15.0 vs 17.6). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. viviTalk sells 4 in-app purchases, starting at $9.99 per month and DejaVocab sells 10 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

DejaVocab holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: DejaVocab has 67 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 96% of viviTalk's written reviews are positive against 87% of DejaVocab'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 weekly. The most recent releases landed on November 8, 2026 and November 12, 2026 respectively.
