# DinoDex vs Y/n

The clearest difference is ads: Y/n at none against DinoDex's shown. Y/n also leads on ratings volume (5.1K vs 27) and chart position (#15 vs unranked). DinoDex's advantage is review sentiment (86% vs 61%) and rating (4.8 vs 4.5). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. DinoDex sells 9 in-app purchases, starting at $0.99 per month and Y/n sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

DinoDex holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Y/n has 5.1K ratings behind it against 27, so its average is the more settled of the two. Written reviews point the same way: 86% of DinoDex's written reviews are positive against 61% of Y/n's.

DinoDex ships an update fortnightly, Y/n every 10 days. The most recent releases landed on September 23, 2026 and September 25, 2026 respectively.
